The domestic window market today offers a huge number of models made of plastic profiles, for the production of which various components are used. All these products are designed to solve a wide range of problems and must be used strictly for their intended purpose. After all, their aesthetics, service life, ease of use, as well as the ability of these structures to retain heat, block out street noise, and reflect excess thermal energy from the sun depend on the equipment of windows. Our article provides basic information about all the main components and recommendations from experienced experts who will help you choose the right plastic windows from PVC profiles.

Advantages of plastic windows

One of the main advantages of modern plastic windows is that each customer can choose a product to suit their individual needs. Thanks to this, buyers spend money rationally and successfully solve problems in creating comfortable conditions for work and living. At the same time, windows made of PVC profiles have advantages common to all types of products.

Durability

Plastic products with minimal care can last at least half a century. To do this, it is enough to carry out service maintenance, do not use it to clean the elements. window designs abrasive and aggressive agents.

Tightness

Provided that the installation is carried out correctly, products from profile systems with double-glazed windows are completely sealed structures. They do not allow air or water to pass through. All condensate formed inside the frames and sashes is drained outside by gravity through special drainage channels.

Functionality

Plastic windows are easy to operate, their opening mechanisms are practically trouble-free in operation - there is virtually nothing in them to break. Active shutters open silently, do not creak during movement and do not jam. In the vast majority of cases, unbalance of opening mechanisms can be quickly eliminated by adjusting and lubricating them.

Sound and heat insulation

Even economy-category models retain heat well and block out street noise. As the class of products increases, these properties improve.

Color fastness and practicality

Plastic windows do not fade in the sun and do not change their original color. Their internal or outer surface easy to clean because the plastic does not absorb dirt.

Form stability

Polyvinyl chloride forms strong connecting seams, does not swell when exposed to moisture, does not melt under the sun, and does not crack in the cold. Reinforced profiles do not deform due to temperature changes and withstand external mechanical influences well.

Main technical characteristics of plastic windows

In Russia, regulatory requirements for plastic windows are listed in industry standards. All of them are most fully reflected in GOST 23166-99. This document contains information about the main operational characteristics window designs:

1. Energy efficiency– is determined by the heat transfer resistance coefficient, which shows how much energy is lost through 1 m² of window when the temperature difference between indoors and outdoors is 1 °C. The higher this coefficient, the warmer the windows made of PVC profiles. According to GOST, its minimum permissible value is 0.35 m² °C/W, and the maximum is 0.8 m² °C/W.


2. Tightness– includes water and breathability. In the first case, the standards determine at what pressure difference water will not leak through the elements of window structures. Current standards define a range from 150 to 600 Pa - the maximum value is considered the best. The second indicator informs how much air can penetrate through 1 m² of window at a pressure difference of 100 Pa. The air tightness of windows according to GOST varies in the range of 3-50 m³. In this case, the smaller value should be considered optimal.


3. Light transmittance- measured by a taumeter, which shows the percentage of visible spectrum waves passing through windows. This parameter determines the light transmission coefficient, the minimum value of which cannot be less than 30% (k>0.3). At the same time, for ordinary windows, a light transmission coefficient of 50% (k>0.5) is considered suitable.


4. Sound absorption level– shows how much windows can reduce street noise. The minimum permissible sound insulation is 25-27 dB, and the optimal one is from 34 dB.


5. Resistance– informs buyers what pressure per unit area window structures can withstand. According to GOST, this parameter should be 200-1000 Pa or more.

This regulatory document also provides a detailed classification of products according to their modular dimensions. According to current standards, the area of ​​one door or window block made of PVC profiles cannot exceed 6 m², and each active sash should not be more than 2.5 m².

If a window seller can present not only a certificate of compliance with GOSTs, but also RAL quality standards, then this is a significant plus. These standards were developed in Germany; to comply with them, manufacturers have to comply with even more stringent requirements.

What to look for when choosing windows

Plastic windows are a complex design; its operational and aesthetic characteristics depend on many factors. To order a model that is suitable for specific operating conditions, you need to learn about everything that affects the appearance and functionality of windows.

Double-glazed windows

Several of the most important characteristics of windows simultaneously depend on these structural elements - energy efficiency, burglary resistance, sound insulation, appearance and light transmittance. Double-glazed windows have from 1 to 3 internal chambers into which argon or krypton can be pumped. The use of inert gas helps to further increase the level of noise absorption and thermal insulation of windows.

Types of double-glazed windows	Individual characteristics	Recommendations for use
Single- or double-chamber standard modification	For the production of these models, budget float glass 4 mm thick with good light transmittance is used.	It is advisable to use single-chamber products for use in regions with temperate and warm climates, as well as in unheated country houses. Double-chamber models are recommended not only to increase energy efficiency, but also to improve the sound-absorbing ability of windows
Shockproof	In the manufacture of such models, heat-strengthened or tempered glass of different thicknesses, as well as triplex, are used.	Necessary in children's rooms, recommended in living rooms, as well as in all windows on the top and first floors
Energy saving with one or two chambers	Such models are made using special glasses that are capable of transmitting rays of the visible spectrum and blocking heat waves	Promising models that help save a lot on heating costs and are suitable for use in all climatic zones of the Russian Federation
Multifunctional	For the manufacture of these double-glazed windows, innovative glass with a combined coating is used, which works on both sides of the window - it retains heat inside the rooms and does not allow solar energy to pass through from the street.	Recommended for use with large glass areas and in rooms with windows facing the sunny side
Stained glass	WITH inside double-glazed windows are coated with invisible heating elements that do not affect the light transmittance of the windows and emit heat when electricity is supplied	Allows you to simultaneously decorate windows and reduce the amount of incoming light
Heated	They are made using electrochromic glass with a layer of crystals applied on it, which can darken the window. Requires voltage supply	Needed for equipping roof windows, flat roof hatches, winter gardens, greenhouses, as well as other structures with a large glazing area
Fire protection	Manufactured using triplex and a special transparent gel pumped into the internal chambers	They are used primarily in internal office and retail premises when completing interior partitions and entrance doors.
Electrochromic	For production, glass with a crystalline coating is used, which can change the translucency of windows when voltage is applied.	Recommended for completing office partitions, as well as windows on lower floors, in hotels and bedrooms

Each additional chamber and triplex increases the weight of the glass unit by an average of 40%. This increases the load on the fittings, so it is better, if possible, to give preference to lightweight models with similar characteristics. For example, instead of 2-chamber conventional double-glazed windows, use models with energy-efficient glass and pumped in inert gas.

Automation

Automatic opening systems are designed to facilitate the operation of windows. They are indispensable for people with disabilities, as they allow them to control the processes of opening and closing the doors without assistance. Window automation is needed in facilities with too high openings and increased wind or snow loads. It is also advisable to equip all windows integrated into the roof with such systems. Today on sale are models of drives for different window designs, which can be controlled using a switch, remote control or multifunctional central unit.

Accessories

The fittings are responsible for everything related to opening windows. Thanks to the wide selection of mechanisms, today it is possible to find systems for all occasions.

Type of opening system	In what cases is it used?
Tilt&Turn	Universal type of mechanism for completing all standard windows with tilt-and-turn sashes
Parallel-sliding or sliding	When equipped entrance groups in wide openings, glazing loggias or balconies, as well as completing windows with multifunctional window sills
Swing	For doors, balcony blocks, economy class windows
Combined (“Accordion” or “Book”)	Can be used in openings that are not wide enough instead of sliding or parallel-sliding mechanisms to equip glazing systems for terraces, verandas, entrance lobbies, balconies, loggias
Lifting or folding	It is mainly used when equipping high windows with lifting or folding sashes (transoms), which are located in the lower or upper part of the opening
Mid-suspended	Designed for windows with a vertical or horizontal axis of central opening
Lift-and-slide	When equipping structures with upward (slider) sashes - English or Canadian windows

Devices for additional ventilation

In the autumn-winter period, it is not advisable to open the doors wide to ventilate the rooms. However, fresh air flow is necessary all year round, so it is recommended to equip windows with additional ventilation devices. You can choose a mortise valve that is integrated into the frame or sash structure, or a device. The second type of ventilation is a mechanism that allows you to barely open the window - a small gap is formed between the frame and the sash for fresh air to enter. Both recommended devices make it possible to ventilate rooms in the autumn-winter season without the risk of cooling the rooms.

For some models of supply ventilation valves, it is possible to equip them with temperature and humidity control sensors. The use of such devices allows you to automatically ventilate rooms.

Window shape

PVC profiles can be cut and welded together under different angles, and also bend in different planes. Thanks to this, manufacturers produce not only rectangular or square windows, but also arched, oval, round, triangular, and trapezoidal windows. Convex or concave models with blind or active doors are also made to order. Such structures are used for glazing openings of non-standard shape. Mainly in the under-roof space, attic spaces and dormer windows. Also, with the help of non-standard models, interior designers and architects implement original construction projects.

Frame design features

The availability of technologies for fixing vertical, horizontal and inclined lintels inside frames makes it possible to arbitrarily divide light openings into separate segments. Their shape and dimensions are determined individually. By installing internal PVC profiles, windows are equipped with sashes and vents where the customer needs them. This technology not only makes it possible to implement standard solutions, but also allows for the integration of rectangular sashes into triangular frames and vice versa. Thanks to this, buyers themselves shape the internal content of their windows. In addition to fixing straight lintels, it is possible to install bent profiles inside openings. This further expands the capabilities of customers.

Aesthetic characteristics of plastic windows

The appearance of windows is formed by profiles, double-glazed windows, window sills, and slopes. In some cases, roller blinds, shutters, grilles or awnings are added. Since windows are actually a typesetting constructor, today any combinations are possible. There is nothing restricting customers in this regard, as well as in the choice of decors.

Price

The price of windows depends not only on their dimensions, but also on the configuration and complexity of the work. It is recommended to immediately take into account the cost of installation. The most inexpensive designs are fixed windows made of 2-chamber profiles with single-chamber double-glazed windows. Improving the quality and functionality of models is only possible through the use of more expensive and modern components.

Which windows are best to order?

Double-glazed windows and functional fittings are used today not only for the assembly of windows from PVC profiles, but also for the production of structures made of wood or aluminum. That is, all of the listed modifications, provided they are equipped with high-quality components, will have a high level of thermal insulation, noise absorption, and tightness. Products made of wood and aluminum cost approximately 2-2.5 times more.

This difference is relevant for both economy and standard class models. As a result, when ordering, the best material for the manufacture of plastic, wooden or aluminum windows is selected individually based on the combination of advantages and disadvantages.

Which windows are better - plastic or aluminum?

When comparing these types of products from profile systems, there are no single universal criteria. In some cases it is better to choose aluminum windows, and in others - plastic windows. It is recommended to choose structures made from metal profile systems when glazing large-area openings, partitions in office and shopping centers, as well as constructing entrance lobbies. Sometimes aluminum windows are ordered for cold glazing of balconies and loggias.

Advantages of aluminum windows	Disadvantages of structures made from aluminum profiles
Durability – products can last up to 80 years or longer	Low level of thermal insulation - even insulated products made from profiles with thermal inserts are inferior in this indicator to plastic windows
Rigidity of structures, high dimensional stability of frames and sashes with low weight	Aluminum products are currently worse at imitating wooden windows than windows made of laminated PVC profiles
High level of fire resistance	Aluminum allows not only cold, but also heat to pass through well, so in extreme heat, apartments and houses with such windows can overheat greatly

Which windows are better - plastic or wooden?

Thanks to the use of Euro timber in the manufacture of modern wooden windows, these products retain shape stability and do not crack. That is, manufacturers managed to get rid of the traditional disadvantages of such models. At the same time, as in the case of aluminum products, wooden windows are no better or worse than plastic windows, so the choice depends on individual factors. The determining role in this process is played by the combination of pros and cons of products, as well as the feasibility of use.

Advantages of wooden windows	Disadvantages of wooden windows
Look more expensive and elegant than products made from PVC profiles	Requires additional protection from the street
Provide natural air exchange between indoor spaces and outdoors	Despite modern technologies manufacturing, additional impregnation with protective compounds, over time they can be affected by mold or mildew
High-quality window frames with proper care can last at least 100 years, and the durability of frames and sashes made of PVC profiles is 50 years	Production time is 2-3 times longer than that of plastic or aluminum structures

What are the requirements for a plastic profile?

In Russia the requirements for plastic products this category is regulated by GOST 30673-99. According to this document, polyvinyl chloride profiles are divided into classes - “A”, “B” and “C”. The best characteristics are for class “A” products, and the least requirements are for class “C” PVC profiles. GOST 30673-99 additionally shows how well plastic windows can withstand exposure to ultraviolet radiation and temperature changes.

Plastic

The plastic used for the manufacture of profile elements must retain its shape at 150 °C for at least 30 minutes - not crack, swell, or delaminate. The minimum temperature at which the plastic can begin to soften should be 75 °C. If polyvinyl chloride meets these requirements, this means that the products can be used on the sunny side and will allow you to quickly leave the room through window openings in the event of a fire.

Important for the profile is the impact strength indicator, which reflects the ability of PVC to resist brittle fracture. The minimum permissible value of this parameter is 15 kJ/m². Frames and sashes with such an impact strength coefficient are able to absorb energy from impacts, due to which they retain an unchanged shape and do not crumble into separate fragments under mechanical stress. To prevent window plastic from being fragile, special modifiers are added to PVC during the production process. In addition, the thickness of the internal and external walls affects the ability of the profiles to maintain their shape and retain heat.

The wall thickness of PVC profiles also affects the reliability and durability of welded joints in window structures. The higher this value, the stronger the seams. The service life of welded joints with an outer wall thickness of 3 mm is approximately 50 years. As a result, for the production of high-quality plastic windows, it is recommended to give preference to “A” class profiles.

Reinforcement

Even when 5-chamber “A” class plastic profiles are used for the production of windows, they must be additionally reinforced. This need is dictated by the fact that products made of polyvinyl chloride are deformed in cold or heat - depending on the temperature, the profiles bend in different directions. As a result, gaps form between the active sashes and the frame, and the integrity of the installation seam is gradually compromised. Such processes entail depressurization of windows; this can only be prevented by installing steel liners in the internal chambers.

All high-quality windows today are made only from reinforced profiles. This requirement is contained in GOST 30674-99. According to the regulatory document, the minimum permissible wall thickness of the reinforcing liners is 1.2 mm. Metal profiles must be made of steel with an anti-corrosion coating, the thickness of which, according to GOST 9.303, is 9 microns. Reinforcing liners are attached to the invisible end side of the profiles using metal screws.

Both the sashes and the frames of the window units must be reinforced along the entire perimeter.

Internal chambers and installation depth

According to modern standards, PVC profiles cannot have less than 2 chambers. The number of internal cavities in the components of window blocks affects both the stability of their shape and energy efficiency. Today, windows made from 8-chamber profile systems have already appeared on the market. They are designed for use in regions with harsh climates and in facilities with large glass areas, where it is necessary to reduce heat loss to the minimum possible level. GOST 30673-99 provides a classification of profiles depending on their level of resistance to energy transfer.

The smaller the class, the warmer the windows. Increasing the number of cameras from 3 to 5 increases the cost of the product by an average of 10%. These expenses are fully justified, since up to 30% of the total number heat loss Costs of improving the energy efficiency of a window or door block pay for themselves quite quickly - in about 2-3 years.


The energy efficiency of PVC profiles is also influenced by the installation depth and the total thickness of the internal and external walls. As a result, some 4-chamber windows may be warmer than 5-chamber windows. Moreover, the installation depth depends on both the number of internal cavities and the profile class. It ranges from 58 to 90 mm and determines the stability, energy efficiency and appearance of structures.

According to GOST 30673-99, all profiles are divided into normal and frost-resistant. The first type of product is designed for operation at temperatures not lower than -20 °C, and the second is able to withstand frosts down to -45 °C.

Plastic color

In its normal state, polyvinyl chloride has a grayish color, so when making plastic for various products Coloring agents must be added to it. Currently, two types of paint-painted window profiles are mainly produced:

• white;
• brown.

In addition, it is used to decorate window and door blocks. During this process, a plastic film is glued to the plain white or brown surface of the profiles under pressure and at high temperature. It adheres firmly to the base and can be applied on either one or both sides of sashes and frames. Lamination film is available in a wide range of plain, fancy, and tree-like decors.

Also, when decorating PVC profiles, co-extrusion and painting methods are used. These technologies make it possible to give the surface of windows different colors. There is much more choice when painting - the entire RAL color range. However, better resistance to external influences and excellent aesthetic characteristics are achieved when a coating (plexiglass) is applied to the profile base using the co-extrusion method. Thanks to the use of this PVC technology and decor are actually sintered at high temperature into a single whole.

Polyvinyl chloride and plexiglass equally expand and contract with temperature changes, so this type of decorative coating is considered one of the most durable.

How to choose plastic windows for balconies and loggias

For balconies and loggias today both cold and warm glazing are used. Since the area of ​​these rooms is limited, it is recommended to equip the doors with a sliding opening system. This will help save space, since the elements of the window structure will move parallel to the frame in close proximity to it. If you still decide to use swing doors on the balcony, it is best to install a system for opening the doors outward. Thanks to this, there will be enough free space inside the room.

To reduce the level of heat loss, you need to use warm glazing even in cases where the balcony or loggia is not combined with the apartment. Thanks to this solution, it will be possible to increase the total energy efficiency of internal and external window structures by at least 10-15%. If French glazing to the full height of the opening is chosen for the loggia, the structures should be further insulated. Especially in cases where the loggia is combined with a living room. To do this, it is recommended to use double-glazed windows with electrical heating or energy-efficient coating.

How to choose plastic windows for an apartment

If the apartment is located on the first or last floor, the windows will need to be equipped with elements to increase the level of burglary protection. It is also recommended to limit the view from the street using reflective or stained glass windows. When further furnishing the premises on any of the floors, much depends on which rooms will have windows installed.

Room	Recommendations for window configurations
Living room	Triplex double-glazed windows on the inside of the windows, PVC profiles and window sills selected for the interior design, decorative layout, micro-slit ventilation device, automatic control system for the microclimate in the room
Bedroom	Double-glazed window with shading and high level of sound insulation, supply ventilation valve
Children's	A device for micro-ventilation, blockers for opening sashes, triplex on the inside of double-glazed windows with excellent heat and sound insulation, wide window sills, devices for intensity control solar lighting
Study	Double-glazed window with a high level of sound insulation, a device for adjusting the intensity of natural light
Kitchen	There are no high requirements for the level of noise reduction and energy efficiency of double-glazed windows. It is recommended to install fresh air ventilation devices and install a window

All products with active doors must be equipped with mosquito nets. If an animal lives in the apartment, you need to install “” models in all rooms. Such designs have a reinforced frame, mesh, and fastening system, so that even an overly active animal is protected from falling out of the window.

How to choose plastic windows for a private home

Choosing windows for a private house is slightly different from a similar procedure for an apartment, although the main criteria in both cases are absolutely the same. The existing difference is due to the characteristics of operation. Depending on the type of object, additional requirements are imposed on profile structures.

PVC windows for a cottage

Since at such facilities there is a high risk of entry into the house through windows, additional care must be taken to ensure burglary safety. If in apartments this requirement applies to windows on the first and last floors, then for all cottages it is always relevant. It is also desirable to ensure confidentiality.

Unlike apartments, cottages usually have a window in the bathroom. It must be equipped with fresh air ventilation valves and double-glazed windows with frosted glass, since the mirror coating is effective only during the daytime.

PVC windows for a wooden house

In houses made of timber or rounded logs, you can also install plastic windows if they are made of a laminated profile. However, with this configuration option, it should be taken into account that wooden walls will change color over time, but frames and sashes will not. In addition, when measuring and installing windows in houses made of timber and logs, you must remember that the size of openings in such buildings may vary. This process is explained both by possible shrinkage of the foundation and by seasonal moisture content in the wood.

To avoid problems with the operation of windows associated with changes in the geometry of the shapes and sizes of openings, a casing procedure is performed. To do this, additional frames are installed in the openings, which are able to compensate for deformations. They are mounted in the log house in such a way that they are able to move slightly from side to side. This technology allows you to maintain the shape of plastic windows and avoid their breakage.

PVC windows for a summer residence

If the dacha is uninhabited and empty in the autumn-winter period, it is best to order economy-class windows from a 3-chamber profile. Indeed, in such cases, a high level of energy efficiency is not required, so you should not overpay for it. In all other situations, the same criteria apply to windows for cottages as for models for cottages. To ensure safety, it is recommended to install metal shutters on the openings, which are locked from the inside. Window bars look better, but are less effective.

How to choose a window sill and slope system

Window sills today are represented by several types of practical products. It is advisable to buy them together with the windows so that the team can immediately install all the necessary elements during installation. The best combinations with plastic windows are window sills made of PVC, artificial and natural stone, as well as combined models made of plastic and pressed wood. Some characteristics of these products have significant differences. To choose the right window sill for a plastic window, it is recommended to study and compare the basic properties of models made from different materials.

Type of window sill	Advantages	Flaws
Plastic (PVC)	Easy installation, able to withstand mechanical stress medium strength, can imitate the texture of natural wood	There are restrictions on the width of the canvas, products melt after contact with too hot objects and cigarette ash (average heat resistance limit is 150 ° C), they can turn yellow if not properly cared for
Combined	Can withstand temperatures up to 180-200 °C, have a wear-resistant, beautiful surface made of laminated plastics	There are restrictions on the width of the canvas and the shape of the front surface
Fake diamond	Scratches can be easily removed from the surface, has a high level of heat resistance, and it is possible to make a radius-shaped window sill	It is necessary to pre-order products; they can be made on the basis of a frame made of material (MDF) with low moisture resistance
A natural stone	They look solid, have the highest heat resistance, and allow you to give the front end any shape	There may be problems when inserting ventilation grilles into granite products, low level strength of marble window sills

It is recommended to select slope systems for the decor of window sills. They are a set of sandwich panels and additional moldings - starting profile, corners, platbands. These stacked plastic structures are perfectly combined with window blocks made of PVC profiles. The use of such systems allows:

• quickly improve the slopes, hide all the unevenness on the walls;
• additionally insulate the walls around the frame;
• give the entire window structure in the opening a single style.

There are not only internal, but also external slope systems. They are made of frost-resistant plastic or painted steel. Such external systems protect well assembly seams, hide defects on the surface of the slopes, and do not interfere with the window structure “breathing”. Depending on the modification, these products do not lose their aesthetic appeal for 15-40 years.

Design features of plastic windows

The standard design of a plastic window is a frame divided by vertical and horizontal profile partitions (imposts) with blind and active sashes. Such models are used for installation in vertical wall openings; they serve as the basis for more complex models.

Bay windows

A bay window is a multifaceted structure that protrudes forward beyond the general plane of the facade. Openings in such rooms can be glazed with windows made of PVC profiles. To do this, the individual elements of a complex system are connected to each other using connecting elements (bay windows) and form a multifaceted, completely sealed structure. Functionally, such products are no different from conventional models made of plastic profiles. With the exception of sliding and parallel-sliding systems, they can be equipped with any sash opening mechanisms and additional devices. Semicircular bay windows, depending on the glazing area, are either a solid or prefabricated structure. Some of these modifications are suitable for equipping sliding doors.

Strip glazing

With help strip structures It is possible to glaze linear openings whose area exceeds 6 m². Separate independent sections are connected using special joining profiles that can compensate for thermal expansion of the plastic. Strip glazing using structures made of PVC profiles is best suited for horizontally elongated openings on loggias, terraces, and verandas. Such multi-sectional systems are equipped with both swing and sliding opening mechanisms.

Anti-aircraft lights

This type of window structure is designed to be integrated into the roof. are equipped with blind and active doors; they can have a flat, convex, dome or pyramidal shape. Their production requires reinforced profiles and double-glazed windows, as well as a system automatic control opening and closing windows. These structures are considered universal, as they are suitable for installation in any roof - metal, tile, concrete. Skylights are mainly integrated into flat roofs, but their installation is also possible on a pitched roof.

Winter gardens and greenhouses

Such products are a complex combination of vertical, horizontal and inclined glazing. The construction of such structures is possible only with the use of reinforced profile systems, since during operation they must withstand high wind and snow loads. For better ventilation, active shutters with remote system management. Since the total area of ​​such structures is usually quite large, it is recommended to equip them with energy-efficient double-glazed windows to reduce heat loss.

Dormer windows

Although roof windows are not complex structures consisting of several independent elements, they are fundamentally different from conventional models made of PVC profiles. Since such products are designed to be integrated into pitched roofs, they have reinforced structure, improved waterproofing. The frame of roof windows prevents water from flowing into the interior even when the sashes are open. Experts advise equipping them with heated double-glazed windows to melt snow, and electric drives for remote control doors

How to choose a plastic window manufacturer

It is important not only to choose high-quality and suitable components for the manufacture of windows, but also to decide on the manufacturer. This is not so simple, since there is a possibility of running into scammers or a company with low responsibility. To prevent this from happening, it is recommended to adhere to the following rules:

1. Preference should be given to those manufacturers who have not changed the addresses of their order acceptance points for a long time.
2. The company should have a showroom with all product samples. Moreover, for each type of profile, fittings and all other elements of window structures, the manufacturer is obliged to provide certificates of conformity.
3. Trust the better companies that additionally provide window installation services, provide guarantees and service.
4. You cannot deal with those contractors who promise to produce everything in 2-3 days or refuse to enter into an official contract.
5. A small office without a showroom should alert the buyer - this is how fly-by-night companies collect advance payments for orders within 2-3 weeks and disappear.

Today, services for the manufacture and installation of structures made from PVC profiles are provided by manufacturers and dealers, who can confidently be called responsible contractors. When choosing between them, in most cases it is better to give preference to responsible dealers, although the manufacturers still enjoy great authority. This is explained by the fact that dealers always have a wider range of products, and they also have more well-equipped installation teams and an extensive network of offices. Moreover, their prices are almost always the same as those of manufacturers.

Production time

On average, the full production cycle of plastic windows, taking into account force majeure insurance, is about 2 working weeks. However, in summer and early autumn, manufacturing and installation can sometimes take up to 2 months. This is due to the fact that during the high season, manufacturers have too many orders, so they are forced to shift deadlines. To reduce the waiting time to 5-7 days, it is best to plan the event for the winter. Moreover, during periods of low customer activity, virtually all manufacturers and dealers provide good discounts. Thanks to this, you can save not only time, but also money.

Window installation

Correctly performed measurements, successfully selected components, and high-quality manufacturing of structures do not guarantee good characteristics windows if their installation was carried out incorrectly. Carrying out installation work must be carried out taking into account the requirements set out in GOST 30971-2012. Compliance with this technology guarantees that the windows will fully comply with the characteristics declared by the manufacturers.

Life time

When studying this issue, one must take into account the fact that different elements window design is designed for different time operation. For example, the service life of frames and sashes made of quality PVC profiles today it is 40-50 years, and double-glazed windows remain airtight for 20 years. The durability of the fittings is the same as that of double-glazed windows - about 20 years or 20 thousand full operating cycles (opening/closing).

It is also worth paying attention not only to the durability declared by the manufacturer, but also to the warranty. If they do not exceed 3-4 years, then the windows are probably of poor quality. Responsible manufacturers today provide a guarantee of 5-10 years - the time until the first replacement of seal circuits, as they are confident in the durability of their products. To ensure your windows last as long as possible, it is recommended to have them serviced every 6-12 months.

Cost of plastic windows

The minimum price for a window with a single-chamber double-glazed window and tilt-and-turn fittings, excluding installation costs, is about 2,100 rubles per 1 m². However, such basic models are no longer popular because they are outdated. Today there is an increase in demand for energy-efficient windows of a new generation made of multi-chamber profiles (from 5 chambers) with heat-saving double-glazed windows. Their minimum price is about 3800-4000 rubles 1 m².

What to consider when ordering plastic windows

When directly ordering plastic windows, the buyer receives a lot of information in the process of communicating with a consultant or measurer. Some of the information is secondary, and it prevents some clients from concentrating on the main thing. Here are the main points to consider first when placing an order:

1. For the European part of Russia best option configuration - 5-chamber "A" class profile and energy-efficient double-glazed windows with heat-saving (selective) coating.


2. If the windows face a noisy side of the street with heavy traffic, it is necessary to take care of additional soundproofing of the structures. To do this, it is better to choose 2-chamber double-glazed windows with different thicknesses glass This design absorbs noise most effectively.


3. Products for a children's room must be equipped with shockproof glass and blockers for accidental opening of the doors. In other cases, you can optionally use the recommendations from the table published in our article.


4. When windows are in an area of ​​prolonged exposure to direct sunlight, it is better not to use a dark profile for their manufacture. It accumulates more actively thermal energy and becomes deformed due to overheating.


5. Although the standards allow minimum thickness steel liners of 1.2 mm; for reinforcement of structures, metal profiles with a wall thickness of 1.5 mm are recommended.


6. To ensure safety, it is advisable to equip windows on the first and last floors not only with triplex outside, but also with reinforced anti-burglary fittings.


7. The best way to protect yourself from excess sunlight will be double-glazed windows with multifunctional glass, which prevent the interior from overheating in the summer and retain heat in the winter.


8. If the window sill is planned to be used as a multifunctional surface (table, shelf, stand), it is best to equip the window with sliding sashes. In surfaces that are large and protrude far beyond the radiator, you need to install special ventilation grilles to circulate warm air.


9. A universal option for opening the sashes is a tilt-and-turn one with a micro-slot ventilation device.


10. Large windows with high or heavy sashes, as well as attic models and skylights, are recommended to be immediately equipped with automatic opening systems.

These 10 practical tips will help you order windows that will be convenient and will not cause problems during operation. Such products will be able to keep warm in winter, protect from heat in summer, protect from noise and ensure safety. When searching for the optimal option for completing plastic windows for residential or commercial premises, many customers are interested in the opinions of friends and colleagues. In most cases, it's a waste of time. Only experienced experts have the necessary information, which in any situation is guaranteed to allow you to select high-quality windows from PVC profiles.

Window seller with 17 years of experience Oleg Nikolaevich Litvinov: “So that the consultant can select the maximum suitable windows, the buyer needs to formulate his requirements as clearly as possible. At the same time, the customer does not need to be embarrassed to name the budget he is counting on. Indeed, in this case, a specialist can quickly find the best option. If the offered price does not suit you a little, you should not save - it is better to wait 1-2 months to save the missing amount. After all, a simplified configuration option chosen for the sake of economy will not be able to fully solve the assigned tasks.

The fact that there is a lot of information about metal-plastic windows is not worth mentioning, but this article contains all the most important points that need to be taken into account when choosing these products. Yes, there are quite a lot of nuances, but if you know them, then purchasing metal-plastic windows will not be a problem, and the result will definitely please you for many years.

Sectional window

The window block consists of several parts:

• plastic profile - glazing bead, frame, impost and sash;
• glass unit;
• accessories;
• rubber seals.

Moreover, each of these components has individual characteristics and its own purpose.

Plastic profile

This is the basis of the entire structure, inside which a metal frame is placed - it is this that gives everything window block rigidity. In addition to the metal frame inside plastic profile drainage channels, filters and seals are located. If you look at the cross-sectional profile, you can see a lot cross lintels- these are stiffening ribs that form compartments with air inside the profile. It is these “air chambers” that serve as the determining element of the level of insulating properties of the entire window - the more of them, the higher the level.

The number and location of air compartments is never random; all “roles” are clearly distributed: some chambers serve for fastening fittings, some increase the rigidity of the entire profile, and some ensure a complete outflow of water.

Sash

The part of a window that is attached directly to the frame. The door can open and close.

Frame

This part of the structure is stationary; it is mounted in the window opening.

Impost

This is a crossbar that serves as a support for the sashes. The impost can be located vertically or horizontally.

Beading bead

The double-glazed window is attached to the frame using a decorative frame - this is what is called the glazing bead.

Double-glazed window

It may consist of several glasses (if there are only two of them, then it will be a single-chamber double-glazed window), the space between which is filled with air or a special gas. The glasses are connected hermetically to each other using a special spacer frame.

Sealant

Perhaps this is the most important element in the entire structure of a metal-plastic window - it is he who is responsible for the insulating properties of the product. The seal is made of complex silicones, located along the edge of the glass unit (on all sides), protecting the space between the frame and the sash.

Accessories

This component of a metal-plastic window is the most high-tech and can consist of a large number of different elements - for example, hinges, brackets, rods, and so on. It is the fittings that play an important role in the normal functioning of the product in question and they bear the heaviest loads during the operation of a metal-plastic window.

How to choose a PVC window manufacturing company

There is quite a wide variety of manufacturers of metal-plastic windows on the market; which of them can be trusted and which are unlikely to justify their trust is a complex question. In solving this problem, it is recommended to adhere to the following recommendations:

1. Recommendations from friends, relatives and work colleagues. Even according to statistics, in half the cases people come to a certain manufacturer based on someone else’s recommendation, so it’s worth asking all your friends where they placed an order for the production of metal-plastic windows and whether they were satisfied with the company’s work. No one has canceled word of mouth, so we can firmly say that the manufacturer recommended by friends will be the best when choosing.
2. Length of time the company has been on the market. If metal-plastic windows are manufactured and installed incorrectly, the result will be the same - a quick replacement of all structures. As statistics show, it is precisely those companies that have been working in the market for a long time, have the necessary experience and professional employees on staff - they do not make mistakes at any stage of working with customers.
3. Level of professionalism of employees. Have you chosen a company? Now you just need to call them and chat with a sales representative. What can be found out during the conversation - how many years the company has been operating on the market, whether there is a free measurement service, how much the real cost of metal-plastic windows corresponds to what is stated in the advertisement. In general, whether a professional or an amateur is conducting a conversation with a client can be determined almost immediately, but a personal visit to the company’s office is also necessary - you can study all the offers, get acquainted with current discounts and promotions and check the company’s documents.
4. Review materials and technologies. Usually, in the offices of companies that produce metal-plastic windows, there are samples of plastic profiles, double-glazed windows and other components - a clear example, so to speak. Be sure to get as much information as possible about these samples - what equipment is used to produce metal-plastic windows, what technologies are used. As many years of experience show, if these questions are given a clear and complete answer, then you can completely trust such a company.
5. Information about the company's vehicle fleet. If they have their own freight transport, then the delivery of materials and completion of all work will definitely not be delayed.
6. Contract for services. Even if the buyer liked absolutely everything, you should not sign the contract right away - first study it carefully. What should be specified in the document:

• cost of work;
• terms of work;
• under what conditions are measurements carried out (paid/free);
• dismantling old windows (if such a stage is needed);
• finishing of slopes (external and internal);
• installation of ebb and window sills;
• mosquito nets included.

Note:signing the contract is not the final stage of the work; the customer will also have to sign the work acceptance certificate - immediately ask whether this stage will be present at all.

1. Guarantees. In general, for such products the warranty period can be at least 2-3 years, but too long is also unrealistic. The fact is that some companies give a guarantee to their customers for 15 years or more - this is misleading the buyer, since such periods are not supported by any tests in any company.
2. Quality documents. Be sure to ask the office for quality certificates for window structures and all components. What documents must the seller-manufacturer present:

• certificate of conformity according to GOST for PVC profiles for window and door units;
• sanitary and epidemiological conclusion on PVC profiles for window and door units;
• fire safety certificate for PVC profiles for window and door units;
• DIN ISO certificate for PVC profile (shows stability of product quality);
• certificate of conformity according to GOST for double-glazed windows of the corresponding manufacturer;
• sanitary and epidemiological conclusion for double-glazed windows;
• fire safety certificate for double-glazed windows;
• certificate of conformity according to GOST for fittings for window and door units;
• sanitary and epidemiological conclusion for fittings for window and door units;
• certificate of conformity for finished products - window and door blocks of PVC profiles;
• license for activities in the construction of buildings and structures.

How to choose plastic windows correctly

In order not to make a mistake in choosing the type and type of structure in question, you will need, first of all, to decide on the necessary functions of a metal-plastic window. The following points should be considered:

• requirements for room ventilation;
• the need for frequent opening and closing of the valves;
• what level of light should be in the room;
• required temperature in the room;
• what room humidity is needed;
• what the house will look like from the outside;
• Is additional sound insulation needed?

It is very important to take into account the number of floors of the apartment - this will help you immediately place an order for the production of tinted windows or with protection from intruders. In general, if you are planning to go to a company and order metal-plastic windows, then take with you photographs of the house from the outside, the rooms inside - this will help the professional manager make the best choice for the client.

The next stage is choosing a window based on functionality: thermal insulation, security, sound insulation and ventilation.

Thermal insulation

It is understood that a metal-plastic window should protect the room almost 100% from the penetration of cold from the outside and retain heat inside. What may affect this function of the product in question?:

• the ratio of the window block and the window itself;
• number of doors;
• frame cross section;
• type of double-glazed window - for example, double-chamber or single-chamber;
• connection of window openings.

It is necessary to pay special attention to the double-glazed windows - for example, simple single-chamber structures are not suitable for use in most regions where people live, but in the south they will be the best option. Single-chamber double-glazed windows are often used in industrial premises - their functionality in this case is sufficient.

A double-chamber double-glazed window retains heat much better - by the way, it is most often ordered, but even it is no longer “in trend.” Nowadays, double-glazed windows with low-emissivity glass have entered the market - a single-chamber package with it retains heat much better than a regular two-chamber one. And, by the way, it will cost less.

On thermal insulation properties Metal-plastic windows are also influenced by the type of plastic profile - those that have 4 or more air chambers in their design are of fairly high quality.

You shouldn’t skimp on fittings either - if they are of poor quality and/or installed improperly, then the tightness of the entire metal-plastic window will be compromised, which means there’s no need to talk about thermal insulation.

Noise insulation

Windows with conventional glazing are considered a poor barrier against the penetration of sound waves, but plastic windows have a fairly high level of sound insulation. The only caveat is that if, for example, tram tracks pass under the windows of the apartment, then noise and vibration will in any case penetrate into the premises through solid bodies.

For the sound insulation properties of metal-plastic windows to be truly excellent, the structure must have at least two gaskets around the entire perimeter, and the density of the window block must be very high. You should also carefully monitor the installation of the window structure - the seam between the opening and the window must be completely sealed, there should not be a single area that is not foamed. Remember - any violations of the density in the entire window structure will lead to a decrease in the level of sound insulation.

Ventilation

It is needed not only for ventilating rooms (open doors can handle this), but also to ensure normal humidity levels in the room and remove excess moisture. Metal-plastic windows are sealed and do not let air into the room through them - this, of course, is a big plus, but if in an apartment or private house ventilation system does not operate within normal limits, then the problem of accumulating condensate will certainly arise. This problem can be solved in one of the following ways::

• regularly ventilate the room using transoms or sashes;
• carry out slot ventilation;
• use air supply devices, which are mounted between the double-glazed window and the frame;
• ventilate with control valves - they are installed outside the metal-plastic window on the outside of the building.

Premises protection

The more cameras the structure has, the higher the burglar-resistant qualities of metal-plastic windows. Some manufacturers, to increase protection against penetration through metal-plastic windows, strengthen the glazing beads - holes are drilled in them, then the glazing beads are attached to the frame or sash, and the flaws are covered with a decorative strip.

It will be possible to install a handle with a lock on the windows - that’s also reliable way resist intruders. By the way, in Europe only such metal-plastic windows are recognized as protective.

If an office or apartment is located on the ground floor of a building, then you can install not standard glass in the windows, but triplex or special tempered glass. In the first case (triplex), even when trying to get inside the room, the glass will not crumble into small fragments, but will remain on the film - this will detain intruders. If you use tempered glass, it is resistant to both shock and temperature changes.

Absolutely all information available in this article must be presented to the potential customer by the office manager. It is the manufacturer’s consultant who is obliged to offer the best option for metal-plastic windows that will meet all the buyer’s requirements.

Plastic windows have long ceased to be a luxury: you can find them in offices and shops, as well as in mansions and private homes. And if previously only a few could install them, now, thanks to a competitive price, the advantages of PVC profile windows have become available to a wide range of people. Convenient and inexpensive, modern plastic windows are easy to repair, unlike their outdated wooden counterparts, so they are being ordered more and more often. But in order to install high-quality products, you need to understand them well - and this article will objectively tell you how to choose the right plastic windows and what characteristics to look at first.

What to look for when choosing windows

Experts judge the quality of PVC windows by their profile, namely by what materials were used to create the window frames and sashes. Decent examples have a complex design and are made of polyvinyl chloride and metal, usually steel or aluminum. The sectional design of the profile consists of several chambers - longitudinal cavities with sealed walls between each other. The strength and warmth in the room will depend on the number of cameras in the windows you choose.

As is the case with any products, the production of plastic windows abroad and in Russia is carried out according to standards, in our country this is GOST 30673-99, the European standard is called EN 12608 SR. It is worth saying that according to its key factors - thickness internal partitions and the thickness of the external contour - domestic and foreign standards are similar. Therefore, made exactly according to the standard, Russian windows made from PVC profiles will not be inferior in quality to “foreigners”.

According to the two main listed characteristics, all profiles are divided into three classes, designated by Latin letters. Let's look at the classification in more detail.

The thickness of the internal walls in profile A windows starts from 2.5 mm, the external walls, in turn, from 2.8 mm. And this profile is optimal for installation in residential buildings.

In the B-class profile, the internal walls of the chambers are made from 2 mm, external ones - from 2.5 mm. Due to their smaller thickness, the structure is not so resistant to loads; such windows can be installed in both unheated and heated rooms.

The object profile or class C profile is distinguished by non-standardized wall thickness, but at the same time they are thinner than in the two previously described profiles. The design is intended for unheated premises, and therefore monolithic: the doors are made without an opening/closing mechanism.

To enhance the strength characteristics, internal strips of metal are included in the design of windows, which is why such windows are rightly called metal-plastic. As for the second structural element, polyvinyl chloride, it is valued by window manufacturers for its unique characteristics:

Environmental friendliness of the material

Durability

Low cost

Conducts heat poorly, which eliminates its loss

Also blocks sound waves, providing owners with peace of mind

Excellent weather resistance

High adhesion rate when applying varnishes and paints

Possibility to make a structure of any shape

Determining how high the quality of the PVC profile is

If lamination of decorative film is not installed on the external parts of the window, then the condition of the plastic can tell a lot about the windows. For example, smoothness and solidity are features of a high-quality material. And vice versa: spotting and the presence of grains indicate a fake with a short service life; do not purchase windows with such plastic defects.

Fortunately, most window manufacturing companies now offer their own products, so the number of outright low-quality ones among them is small. Another thing is “one day companies” that have recently entered the market, have no reviews but are attracted by the low cost of windows. Such options should not be considered; in general, before ordering, be sure to inquire about the manufacturer.

Large manufacturers primarily use high-quality equipment, since smaller companies will not be able to afford the cost of such machines. It is important that the windows include profiles from the same manufacturer, and that they are securely fastened together using mechanical hardware or a welding machine.

How do air chambers affect the quality of PVC windows?

In order for a plastic window to have excellent thermal insulation and a fairly durable structure, it is divided into several internal cavities. The outer row of chambers in high-quality windows is equipped with small holes: this allows liquid condensation, which forms due to the difference in temperature indoors and outdoors, to be removed from the window. Therefore, such windows last much longer, without negatively affecting the thermal insulation of the openings.

First of all, thermal conductivity is affected by the number of chambers in the window. If you plan to glaze loggias, balconies or technical rooms, then there must be at least three internal cavities. If installed in educational establishments, hospitals, shopping centers and residential premises there must be at least five cells. It’s not worth chasing a large number of them; for example, windows with seven chambers have increased weight, and because of this they begin to conduct more heat. Partition materials have greater thermal conductivity compared to air, so their excess leads to heat loss.

Separately, we note a new type of windows in which the chambers are filled with a special heat insulator in fiberglass or foam form, rather than with ordinary air. In such windows it is possible to achieve excellent thermal insulation even with a small number of chambers, but along with the thermal insulation qualities of such products, the price increases sharply, so they are affordable to few.

The width of the profile is also worth considering if you want to choose really high-quality and warm plastic windows. Otherwise, this parameter is called installation depth, and its standard value is from 50 to 80 mm. Let us add that with a frame width of about 60 mm, the number of cameras in it is limited to three, but if the figure reaches 70 mm, then we may have windows with 4-5 cameras. Accordingly, with wide frames, it becomes possible to install more durable fittings and high-quality sound and heat insulation. Therefore, the installation depth is directly proportional to the quality of the windows.

Quality of double-glazed windows

The extent to which your window will transmit light and save heat will largely depend on the characteristics of the double-glazed windows, so this element is not the last one to choose. And the deeper the glass unit is planted, the better. For example, with a frame depth of 50 to 70 mm, the distance from outer surface glass to the outer frame cut is at least 18 mm, which is optimal. When choosing windows, this turns out to be even more important than the number of cameras, since if the depth of the package is less than 15 mm, the glass will fog up and freeze too quickly.

Key points when choosing double-glazed windows

When performed with high quality, this window component perfectly protects against noise and allows sufficient quantity light into the room and also retains heat in it. Therefore, in many ways overall quality Windows are determined precisely by the quality factor of the double-glazed windows. What should you focus on?

Dimensions

According to this indicator, double-glazed windows are currently produced in several standard thicknesses: 24 mm, 26 mm and 32 mm. However seats Different manufacturers differ, and therefore the depth of installation of the double-glazed window - this must be provided for when purchasing. The size restrictions available for windows dictate the maximum glazing area, so for single-chamber packages it should not exceed 3 square meters. m. with a glass thickness of 4 mm. If the glass reaches a thickness of 5 mm, then the area indicator increases to 4.2 square meters. m.

Glass type

A variety of types of glass are used in double-glazed windows, and in each case this affects the characteristics of the window. Therefore, it is necessary to understand in particular detail the differences between different types of glass.

There is the following classification of glass types in double-glazed windows:

With a matte effect

Mirror

With applied tint

Transparent

Spray coated

Impact resistant

Self-cleaning

Most often, each type is based on float glass High Quality, reaching from 3 to 6 mm in thickness. Although there are double-glazed windows with glass 8, 10 and even 12 mm thick, such products are produced on an individual order basis - for example, when it is required to make transparent walls from glass or the double-glazed window will be installed as an insert in the front door. Typically, a thickness of 4-5 mm is sufficient for windows - with this indicator, the standard light transmittance is 90%, and also provides acceptable heat conservation, strength and noise blocking.

What will a visual inspection of double-glazed windows indicate?

There are several signs that, upon external inspection of a double-glazed window, will indicate the level of quality of the product. First of all, look for the markings indicated by the window manufacturer in their data sheet. As a rule, the marking contains the company logo, the date of manufacture of the glass unit, and information about the components used. If there are no markings, you should be suspicious of the glass unit in front of you.

Other obvious factors are that you should avoid windows with cracked glass units, or if there are chips and other defects in the plane or at the ends. If, when studying the perimeter of the chambers, a liquid sealant substance has noticeably leaked, then the sample in question was clearly made at home, in violation of production standards. The condition of the outer layer of sealant will also indicate low quality: if in excellent double-glazed windows it is perfectly aligned and smooth, then in counterfeit products cracks and inhomogeneities are noticeable.

No less important is the geometric accuracy of the shape; to determine the quality of the product, diagonals are measured. If, on a window side of 1.3 m, the diagonals differ from each other by more than 3 mm, then the dimensions of the product are not met accurately enough. In the case of a window side up to 2.3 m, the deviation from the norm will be a difference of more than 4 mm. To find out how much the thickness of the glass unit meets the standards, a caliper is used, and deviations of a millimeter or more are not allowed.

Continuing to study the geometric perfection of a double-glazed window, prepare a square - when measuring displacements of the glass plane, a deviation of more than a millimeter is a defect, regardless of the thickness of the product. To visually understand whether there is steam and moisture inside the glass unit, look through it at the light.

All specified deviations indicate that the product does not meet the standards. By paying attention to these factors, you can be guaranteed to choose the ideal double-glazed window without consulting specialists.

The characteristics of plastic windows are also largely influenced by how thick the internal partitions and external walls of the profiles are made. For example, if the thickness of the outer walls is less than 2.5 mm and the thickness of the partitions is less than 2 mm, the window is not recommended for installation in residential premises, schools, offices and hospitals, since proper protection from cold air will not be provided. Such windows are suitable only for warehouse complexes or garages and workshops. Also, excessively thin walls limit the size of window structures - it will not be possible to attach durable fittings to them, which means big windows will be too fragile.

However, it is impossible to check the thickness of internal partitions by eye, so the main condition for choosing high-quality windows is to contact reliable companies. And remember that in addition to thermal insulation, sufficient wall thickness in the profile ensures the stability of the window geometry, its strength and resistance to mechanical stress, so you should beware of unfamiliar brands - in this case, there is a high risk of getting a fake product.

Also responsible for the strength of the profile is a metal reinforcing element, which is installed in the middle chamber of the window, the largest of all. A metal insert is necessary, since even PVC modified with chemical additives still remains a fragile material. And only a reinforcing liner will make the future window sufficiently resistant to impacts and other loads. Also, it is to the metal that all window fittings, which is very abundant in modern products.

The insert is made in the form of the letter P or has a square shape and is cut from a sheet of metal with a thickness of one and a half to two mm. Also, in order to reliably resist the negative effects of corrosion, the reinforcing element is made exclusively from steel coated with a protective zinc layer.

Be sure to check the presence of a reinforcing profile when purchasing, since without it, the windows will be guaranteed to deform in hot weather, just as in cold weather. And although it is unlikely that the double-glazed window will collapse because of this, problems during closing and deterioration of tightness are guaranteed.

The impact of low temperatures on plastic windows

A particularly important parameter when choosing PVC windows is their frost resistance, because the temperature in your premises will depend on it when low temperatures set in. The degree of resistance to temperature changes is marked with a special index, and in Russian climatic conditions windows marked “M” are required. It means “frost-resistant,” which means the windows will retain their properties even in frosts down to minus twenty degrees.

Note that cold resistance, among other characteristics, is indicated in the technical data sheet of the window, and you can easily check this. The document states that the profile is of the frost-resistant or normal type, then these windows can be purchased without fear, since they provide for the use of the window at low temperatures.

Choosing a suitable plastic window seal

In order for double-glazed windows to reliably retain heat and at the same time not allow extraneous sounds to pass through, they must be sufficiently airtight. This most important quality PVC windows directly depend on the quality of the sealant used. Sealing agents should be laid around the entire perimeter of the window sashes. If this condition is not violated, then cold air and humidity will not be able to penetrate into the room through the window, and you will not be disturbed by street noise.

What qualities does a high-quality seal have:

High strength characteristics

Sufficient elasticity

Long lasting color fastness

Resistant to both high and low temperatures

No irritating “chemical” odors

If, during the operation of the window, the sealing material has worn out and lost its characteristics due to chemicals, temperatures or mechanical influences, then it can be completely replaced on your own. The main thing will be right choice material, because there is a large amount on sale different options to seal the window. They differ not only in price, but also in some key characteristics. The most popular sealing materials among consumers are silicone, thermoplastic, rubber, and thermopolymer.

We extend the service life of the seal

And yet, in order to avoid premature wear of the sealing elements, it is necessary to properly care for them. First of all, they require regular cleaning from accumulated contaminants and lubrication - silicone oil or, in its absence, ordinary glycerin, may be suitable for this.

Please note that sealing materials do not tolerate cleaning agents and solvents, both synthetic and organic. Instead, it is better to wash off the dirt using a cloth soaked in a solution. warm water and neutral household cleaning products, and after drying, be sure to apply a lubricant. Such simple care for seals can extend the service life of PVC windows by several years, which means you will spend less on their repair or replacement.

Decorative qualities of plastic windows

Interest in windows with a plain white profile is rapidly declining, and products with “wood” decor are becoming increasingly popular. To give a certain color the profile can be processed with polymers, for example, an acrylic coating is applied, or lamination is performed. In windows of a higher price category, special overlay strips made of metal or wood are responsible for the color; they are attached to the profile with special fasteners from the outside and inside of the window.

However, if you are interested in imitation of noble wood, you should be prepared for a slight increase in price. In addition to cost, decorated windows also differ in other qualities. For example, a profile with a dark color will heat up somewhat faster, which means that such a product must have a reinforcing metal liner, regardless of whether the window is small or large in size.

In addition to the color characteristics, the decorative side also affects the geometry of the window, so the standard shape is increasingly inferior to windows with rounded corners or even more complex products.

So, when choosing plastic windows, you can easily choose products that are acceptable in quality and price - just follow the tips presented in this article. Pay special attention to the quality of double-glazed windows and carry out mandatory maintenance in a timely manner. installed windows- then you will save yourself from unnecessary costs, and your home will be quite light, quiet, warm, and therefore comfortable for many years.

How to choose high-quality plastic windows? This question interests everyone who is thinking about purchasing and installing them. At the moment, hundreds of organizations provide their services in this area, but it can be difficult to choose something suitable and of truly high quality from the numerous options.

Main principles of choice

Current plastic windows are complex system, which includes several elements. However, among them it is impossible to name those that are main and those that are secondary in purpose.

The main mistake people make when choosing is focusing on a specific brand.. It is clear that most advertised brands attract with their popularity, but they can greatly disappoint the buyer, since the appearance does not always reflect the content.

The first thing the buyer must decide is the purpose of the windows, the needs for their purchase and installation. In addition, you should understand some of the nuances that relate to the design of this product. Technical specifications are completely dependent on operating conditions, therefore, when choosing windows, three factors should be taken into account.

The first factor includes the temperature regime of the room in which the products will be installed. This also applies to the climatic conditions outside the building. Subsequent factors include noise level and associated load, safety requirements. Therefore, such points as the location of the windows towards a quiet courtyard or a busy street, the floor on which the apartment is located, the room that will require plastic windows, all of this together is of considerable importance when choosing.

How to choose a profile?

The main element from which the profile for plastic windows is made is polyvinyl chloride (PVC). The service life of the entire structure, appearance and characteristics depend on the quality of this material, since the profile is considered the basis of this product. You should only choose a product that has been certified and meets current quality standards.

When choosing a company, you should take into account that today's market is literally divided into different groups. You can find inexpensive brands or brands that occupy an intermediate position. Many Russian companies produce their own windows and can easily compete with European manufacturers. However, they use raw materials and equipment from European countries.

Profiles from Western Europe constitute a high price segment; they are manufactured only outside of Russia. Most experts are convinced that there is no significant difference between the products different companies, however, they advise you to beware of economy class products, that is, the lowest in cost.

In addition, they state that the important indicator is the characteristics of the product, and not the brand name and its popularity. It is the characteristics that you should pay more attention to.

The profile also performs a load-bearing function, which emphasizes its importance. The statistical indicators of windows are influenced by the profile dimensions, its length and width. For massive sashes and frames, a third sealing circuit, anti-burglary elements, a wide double-glazed window and larger number air chambers. It is worth noting that the wider the profile, the better it is, but purchasing such a product will be expensive.

The durability and strength of the profile is influenced by the thickness of the outer walls. If you follow the requirements of GOST, then middle-class windows should have a thickness of at least 3 mm. It is worth noting that there is a lightweight version for economy class, in which the thickness is reduced to 2.5 mm.

For sound and heat insulation, air chambers play an important role, at the same time acting as stiffeners. A large number of cameras indicates that these qualities are at the proper level and the higher their number, the better the sound and heat insulation performance. For unheated rooms and premises or for temperate climates, three-chamber windows with a width of 58-60 mm are quite suitable. For most regions of Russia, it is recommended to purchase five-chamber windows with a width of 70 mm.

You should also pay attention to the reinforcing liner that will be used in production. It is used to impart the necessary rigidity to the structure and stabilize the shape and linear dimensions, which can change under the influence of external factors, such as weather conditions. The liner is inserted into the main chamber of the profile. It is made of galvanized steel, the thickness of the sheet will be 1-2 mm.

Thus, when choosing a window profile, you need to pay attention to several points. Special attention deserves the number of chambers, profile dimensions, including wall thickness, height and width, characteristics of the reinforcing liner and its presence.

Selecting a double-glazed window

The need for a high-quality double-glazed window is that it provides protection from extraneous noise and allows you to provide the necessary thermal insulation. In addition, double-glazed windows are multifunctional, and since they make up the majority of the window, their role increases significantly.

The main factors on which the choice of this element depends are represented by the level of noise exposure, climate characteristics, and safety requirements. These can also include such an aspect as the appearance of the product, but this is up to the buyer’s choice.

The choice of double-glazed windows is represented by a variety of designs, among which there are single-chamber and double-chamber, heat-saving and so-called safety double-glazed windows. In addition, there are also sun protection products.

The single-chamber design is represented by two glasses, between which there is free space. Depending on the thickness of the glass and the size of the spacer frame, their thickness ranges from 24 to 26 mm. Such designs, which do not have technologies for saving heat, are suitable for warm climates and unheated rooms with good ventilation. Otherwise they will often fog up.

Double-glazed windows have high levels of sound and heat insulation. The total layer thickness is 32 mm, so they are well suited for central Russia. This type of double-glazed window is represented by a design of three glasses, which improves the characteristics of the window.

Glasses can be located at different distances, depending on the model and manufacturer. IN different models this distance can be 6 or 16 mm. This makes it possible to withstand noise effects with varying effectiveness and improve thermal insulation properties. As for insulation, some manufacturers resort to technical tricks, increasing the thickness of the outer glass from 4 to 5-6 mm. This step allows us to improve insulation performance in this category.

New technologies in the manufacture of double-glazed windows

To reduce heat loss or save it, energy-saving windows are used. There are designs with soft or hard surfaces. The first option is represented by a film applied to the glass itself, while the second type involves the application of thermal insulating material during the glass production stage. The material transmits light well, but reflects heat in the direction from which it is generated. That is, this technology will not lead to loss of thermal energy.

In addition to the fact that heat loss is greatly reduced, the room heats up less in sunny weather, which is good during hot weather. Another advantage of these windows is that condensation does not appear on the windows, and the material protects home objects from the harmful effects of sunlight, which leads to furniture fading.

Another option for energy-saving technologies is filling the window chambers with gas. The gases used have a lower thermal conductivity and transfer heat more slowly than air. This leads to a decrease in heat transfer, resulting in a reduction not only in cooling the room, but also in the cost of heating the room.

As for the safety double-glazed windows, these windows have a polymer layer called triplex. When external influences are applied to the surface of window glass, the fragments do not fly apart in different directions, but remain in the specified layer, as a result of which the possibility of getting hurt or causing injury to oneself is reduced many times over.

Thus, the choice of double-glazed window plays a big role, since not only the quality of the window, but also its characteristics depend on it. As with the profile, you should not give preference only to famous brands; you need to familiarize yourself with all the parameters in detail. This also applies to new technologies used in manufacturing.
