The formation of polyvinyl chloride windows into a full-fledged segment has long been completed in the domestic market. Technological and functional frames have confidently replaced their wooden counterparts, providing the consumer with reliable and ergonomic glazing. However plastic profiles For PVC windows, users have mixed opinions, which is due to the variety of models and quality parameters of these products. Often, the manufacturer's brand becomes the decisive selection criterion - certified windows are more likely to be endowed with the qualities and characteristics declared by the company. All that remains is to figure out which brand guarantees the best profile properties.

What is a PVC profile?

A metal-plastic profile is a frame that can include up to eight chambers, but models with two or three compartments are more common. Actually, they generally depend on their parameters. It is logical that options with a larger area are weaker in insulating and soundproofing functions than plastic profiles for small windows. In order to increase thermal insulation, manufacturers use polyurethane foam, which fills the space of the chambers. Fiberglass coating is also common with In the list of main distinctive features profiles and installation width are indicated. The rigidity of the structure and, consequently, the reliability of the valves depends on these indicators.

Foreign profile manufacturers

For the most part, imported PVC windows are represented on the market by German products. Technologies of European companies have come far ahead and today dominate this niche. The list of companies numbers in the dozens, and the leading positions in quality and sales are occupied by the brands KBE, Rehau, Veka, Trocal, Deceuninck, etc. It is noteworthy that the windows of most German companies are manufactured in Russia under special licenses. Accordingly, many plastic profiles for PVC windows, the names of which are of German origin, are produced in our country. Domestic manufacturers of brands such as Rehau and KBE strive to ensure proper quality by completely recreating the original

Russian profile manufacturers

Despite the wide representation of foreign window products, Russian manufacturing technologies are also being improved. One of the oldest domestic manufacturers of metal-plastic profiles is the Proplex company. Having initially mastered Austrian technologies, the company strives to offer a wide range of glazing products.

The formation of the Montblanc brand was not without help from Austrian specialists. Currently, the company's clients have access to plastic profiles for windows with a maximum width of 120 cm - this is a system that includes five chambers.

The Novotex company, which has production facilities in the Moscow region, can perhaps be unconditionally called Russian. Engineers and technologists are constantly working to improve plastic structures, focusing on local climatic conditions. It is the latter factor, combined with a low price, that allows the Novotex brand to maintain competition.

Class A profiles

Although the quality of profiles is determined by general criteria, there is a division into classes, according to which comparison of premium models and representatives of budget series is unjustified. The former obviously win in performance and durability, while the advantage of the latter is the price.

So, luxury plastic profiles for windows are positioned on the market as A-class. Such systems are distinguished by their wall thickness (3 mm), reliable connections in the corners, and protection from external influences. The technical features of A-class profiles are not felt during use, which, however, indicates the reliability of the structures. They are very problematic to dismantle without a special tool, an optimal microclimate is created in the room, and aesthetic beauty with the possibility of tinting the frames makes premium systems the best choice. Representatives of the A-class include profiles KBE, Rehau, Veka, etc.

Class B profiles

You cannot count on impeccable technical and physical parameters in the windows of this group, but due to the relatively low cost, this product also deserves attention.

The thickness of the outer walls in B-class structures is 2.5 mm. For this reason, plastic profiles for PVC windows of class B are less resistant to physical influences. There is also an opinion about the unsatisfactory environmental performance of profiles of this group, but this is not true. Non-toxicity is a general condition for certification of plastic structures.

Category C profiles

In general, modern C-class profiles fully meet consumer needs both in terms of sound and heat insulation, and decorative properties. Another thing is that premium competitors have raised the level of technical qualities quite high.

Representatives of category C include profiles of such brands as Vektor, LG Hausys, AGF, as well as almost all domestic products, including Novotex. As a rule, they are used to provide non-residential premises, but there are also lines aimed at installation in apartments and private houses.

Rating of the best profiles

Against the backdrop of the development of technological methods for producing profiles and fierce competition, it is not easy to identify. The rating is formed based on a combination of qualities and the introduction of fundamentally new properties. In this regard, the arrangement of leaders can be presented as follows:

This brand has earned its championship by maintaining an unsurpassed level of basic qualities of window profiles. These include 50-year durability, increased heat and noise insulation performance, as well as environmental friendliness due to the addition of zinc and calcium compounds to the PVC formulation.

Constituting serious competition to KBE, the Veka brand takes second place. The list of its advantages includes the technology of manufacturing “light” profiles, which at the same time ensure the preservation of heat and acoustic comfort.

3.Rehau

Rehau is rightfully among the top three. The quality of the profiles of this manufacturer is achieved through the introduction of lead compounds. As a result, the structures acquire high strength and stability in operation.

The following positions can be occupied by many plastic profiles for PVC windows. Which one is better among them should be determined by the same parameters. The Salamander and Deceuninck systems should be added to the top three. Although plastic profiles for windows of these brands are not so popular, their physical and technical qualities maintain a high level. They are also distinguished by ergonomics and thoughtful configuration, which facilitates installation and further use of window systems.

PVC windows dominate the construction market. Why are they so good? What are the highest quality plastic windows? We will try to answer these, as well as many other questions, in detail.

Expert opinion

Anton Tsugunov

Hello, friends!

Let me clarify right away that a window is not easy. good profile or an expensive double-glazed window. A window is a complex technological product and its quality is influenced by many components. In the article we tried to reveal all aspects that affect the efficiency and reliability of the design.

I personally participated in the installation and operation more than 200 window units, so I tried to give your recommendations under each important point.

For convenience, use the table of contents, it is active! When you click, you will be taken to the desired section of this useful material.

Design

Metal-plastic (plastic) windows, despite their apparent external simplicity and unpretentiousness, consist of many parts, some of which are not visible upon superficial inspection. Each component has its own purpose, they are all a product of innovative production.

Main components of the structure:

• fastening strips - glazing beads.

The components also include:

• low tides;

In summer, windows are open for a long time to ventilate rooms. And to prevent insects from entering the house, they are equipped with removable mosquito nets.

PVC window systems are reliable, convenient, and quite inexpensive. Their advantages also include a high level of maintainability. If any window component fails, it can be easily ordered and replaced.

What plastic for windows can be: quality and properties

For the production of frames, two types of PVC are used: matte and glossy.

Samples of the first type are cheaper, but their surface is slightly rough, which can be felt with your hand. Such frames absorb dirt like sponges and gradually turn from white to gray with streaks. Clean them thoroughly using standard detergents will not work.

Samples of the second type are more expensive, they are also easy to identify by touch - the surface is smooth, as if polished. Such frames repel dirt and are easy to clean with conventional tools and products. In order not to run into low-quality goods, it is better to buy metal-plastic windows from well-known brands.

In addition to many advantages, polyvinyl chloride also has disadvantages that companies producing window units are forced to take into account.

Here are the main ones:

• Low level of strength. This is compensated by reinforcing steel inserts. The structure is also equipped with internal partitions of a certain thickness, which act as additional stiffeners.
• Low resistance to temperature changes, low resistance to impact ultraviolet rays. This can be eliminated by adding stabilizing as well as modifying particles to the polyvinyl chloride composition. In high-quality PVC they are not hazardous to health.

If a metal-plastic window is a source of an unpleasant pungent odor, then you should refrain from purchasing it. Most likely, an unscrupulous company saved on quality additives by replacing them with cadmium or lead.

• Significant level of linear expansion. The indicator is one to two millimeters per 1000 millimeters of profile length. This feature of the material is mitigated by reinforcement, precise calculation of fasteners, and compensating gaps are also provided in the design.

What does a PVC profile consist of?

The plastic frame is not uniform. In addition to the plastic base, it includes profile reinforcing elements and sealing gaskets.

Read more about how to choose a PVC profile in our separate section.

The window plastic base is made of polyvinyl chloride (PVC), two-thirds of this material consists of a type of chlorine that is not hazardous to health. This type of plastic does not emit a characteristic odor and does not deteriorate when exposed to low temperatures in winter (maximum - 25 degrees), retains its given shape in extremely hot weather in summer (up to + 65 degrees).

PVC structures have good waterproofing properties and a high level of moisture resistance. PVC window systems are suitable not only for the living room or bedroom, but also for rooms with high humidity levels (kitchen, bathroom).

Rubber gaskets ensure the tightness of the window system; they seal the contours of the frame and glass unit. This type of seal is specially designed: if it becomes unusable, it will not be possible to change it without special skill; you will have to call a specialist. The sealing of the sashes and seats of double-glazed windows is standard and can be easily replaced if necessary.

In order for the double-glazed windows to sit firmly in their seats, plastic fastening strips - glazing beads - are used.

Classes and installation width of the profile according to GOST

Historically, the installation width (the distance between two outer planes) of wooden window systems in multi-story buildings residential buildings in the countries of the former USSR it is from 58 to 60 millimeters. These dimensions according to calculations correspond to the temperature specifics of the climate of Eastern Europe. Most plastic windows that have replaced outdated wooden windows have a similar installation width. The indicated overall dimensions are sufficient for installing a three-chamber system, which is popular in our market.

If the apartment is located at the top of a high-rise building or the local climate is characterized by strong winds and low temperatures, then a four- or five-chamber model should be installed. This window has an installation width of 70 millimeters.

There is no direct relationship between the width of the frame and the number of cameras. For example, there are models with three chambers, with a mounting width of 90 millimeters. The thermal insulation parameters in such a window system are much better than those of multi-chamber analogues.

This is explained by the fact that the thermal insulation properties are improved not by the number of chambers, but by their dimensions and the volume of air mass contained in them.

The main characteristic of a PVC window profile is the thickness of the front walls and lintels of the internal part. Dimensions, types and other parameters of all components of window systems are regulated technical specifications regulations. IN European Union these are EN 12608 SR standards. Companies in the territory of the former USSR are guided by the following standards:

The technical conditions of the regulations are almost identical; according to these documents, the profile is classified into three groups:

• A-class samples. The smallest value of the thickness of the front wall is 2.8 millimeters, the same indicator for the internal partition is 2.5.
• B-class samples. The minimum thickness of the front wall is 2.5 millimeters, the same indicator for the partition of the internal part is 2.
• Samples of the C-class. This group includes a profile whose parameters do not correspond to the first two classes; it is called object. Typically, the wall thickness of object samples is less than the similar parameters of A and B-class models.

The scope of application of A-class metal-plastic windows is heated residential premises; B-class - installation in unheated and heated buildings is possible; C-class - only in buildings without heating.

B-class windows are less durable in comparison with A-class analogues, their service life is shorter. C-class samples most often represent a monolithic system.

Number of air chambers

In metal-plastic windows, air chambers have a dual purpose.

• Firstly, they prevent heat exchange between air masses indoors and outdoors (thermal insulation function).
• Secondly, they strengthen the structure of the window frame, promoting tightness, strength and for a long time window services.

Temperatures in rooms and in the environment during the cold season vary significantly, which contributes to the formation of water droplets in the cavities of the window system. To remove moisture outside, special holes are provided (on the “street” surface of the profile). They do not affect the thermal insulation performance of the system. To prevent the channels from being noticeable, they are covered with special plugs.

Low-quality cheap PVC windows do not always have such technological holes (they are made at the factory, you should check their presence).

The most popular are three- and five-chamber frames. If the apartment is located in the lower part of a multi-storey building, the window openings face south or west, there are no highways or any noisy objects under the windows, then it is enough to install a three-chamber sample (profile thickness 58 millimeters). The location of the apartment on a high floor, openings facing north or east, a highway near the house - this is a reason for installing a five-chamber window system (profile thickness 70 millimeters).

Several years ago, companies began to make samples in which the chambers were not air mass, but polystyrene foam. With such a filler, a smaller number of chambers in the profile contributes to a higher level of thermal insulation, which is indexed by a special coefficient.

The five-chamber sample corresponds to a thermal resistance coefficient value equal to 0.72 units, and the three-chamber sample – 0.64 units.

Reinforcement

To prevent the plastic base of the windows from deforming during operation, it is reinforced, that is, metal elements are inserted into the cavities around the perimeter of the frame. They are made from steel strip one and a half to two millimeters thick. The workpieces are usually coated with a layer of white zinc, this protects them from corrosion.

It comes with a cross-section in the shape of the letter “P” or in the shape of a square. The second type can withstand significant loads, so window systems with large dimensions are reinforced only with blanks with a square cross-section.

If the length of the frame is less than 80 centimeters, then according to the regulations, reinforcement is not required.

Profile Options

A metal-plastic window block is a complex system, consisting of many components. Polyvinyl chloride profile is used not only for the production of frames, but also for other purposes, for example: when joining window systems at an angle, when fitting, and so on.

The main types of this profile:

• . This type is used for glazing complex structures, the components of which are located in different planes at an angle to each other. Typically such work is carried out in winter gardens, greenhouses, loggias, unconventional balconies.
• . Not always sizes seat are standard and correspond to the installation dimensions of the window unit. In such circumstances, an additional profile is used for adjustment. Its standard width ranges from 20 to 100 millimeters.
• . This PVC element facilitates reliable installation of ebb and flow sills and protects the structure from damage during storage and transportation. Standard dimensions (in millimeters): depth - from 20 to 40, height - from 20 to 30, length - 6000. Depending on the climate, choose a profile with two or three chambers.
• . It is used when installing slopes and connecting them together. It is divided according to the shape of the section, which resembles the letters of the English alphabet (F, I, L, double L). This type of profile is connected with glue or hardware.
• Drain strip. A PVC part that protects the window from rainwater entering when the sash is folded back. Many companies neglect this useful component, although not all models can install it. A drainage strip is not installed on colored window blocks due to the risk of deformation at high temperatures.

Colored windows

Most people choose window systems made of white PVC, but there is also a demand for them, although such windows are noticeably more expensive. The properties of the colored profile differ from white.

For example: colored ones get hotter in the summer. Therefore, in order to avoid deformations, even small-sized parts should be reinforced.

In the production of colored PVC components, acrylic dyes, lamination, spraying, etc. are used. In elite models, multi-colored figured plates are used. The surface of the window itself can be not only flat, but also rounded, corrugated, etc.

How to choose a profile, quality certificates

The market for metal-plastic window systems is crowded with products from different companies. When buying a window, you always want to pay less, but still want the product to be of high quality. However, a good window from a famous brand cannot be cheap, and the high price is compensated by its long, trouble-free operation. A window unit of dubious origin will quickly break, and you will have to spend money again on purchasing a new, higher-quality model.

What should you pay attention to when choosing? In order not to run into a fake and to be one hundred percent sure of the quality, you should purchase goods only from a well-known world brand with an impeccable reputation and a long history of work in the market. The profile must be pleasing to the eye, smooth to the touch, without defects or noticeable unpleasant odor. The dimensions of the window system must correspond to the dimensions of the opening; it is necessary that the thermal and sound insulation properties of the profile correspond to the specific location of the apartment and the climate.

Products must be accompanied by an international quality certificate ISO 9000 and ISO 9001.

• Strength must match DIN 53453 and ISO 179-61.
• Durability of plastic - to DIN 53387 standard.
• Profile hardness - DIN 53456.
• Resistance to high temperatures - DIN 53460 and ISO 306-68.

Most companies produce metal-plastic windows not only for apartments or houses, but also for technical non-residential premises. Such a profile is called an object profile; upon a quick inspection, it is almost indistinguishable from a normal one; there is no marking or there is an inscription “object”.

However, physical and mechanical characteristics of object samples are much worse, Low-grade PVC. To avoid becoming a victim of deception, you can only buy windows from large, well-known retail chains.

Double-glazed windows: design, planting depth, decorative elements

– one of the main components of the window unit, which makes up about 80% of its area. It is responsible for the light permeability of the window and its thermal insulation capabilities. The quality of installation of a glass block in a profile depends on the depth of the seat. In good models, the distance between the frontal plane of the profile section and the outer glass should not be less than 15 millimeters. The optimal value of this indicator for a window system seat depth of 50–70 millimeters is 18 millimeters. Insufficient planting depth of the glass block will lead to fogging or freezing of the windows.

The glass unit consists of sheet glass and chambers filled with an air-gas mixture. To protect the unit from the influence of the external environment, spacers are used. On the outside, viscous compositions are applied to them. polymer based(sealants), which are applied in several layers along its perimeter. These polymer compositions also prevent the gas mixture in the cavity of the glass block from leaking. To prevent moisture from forming in the inside of the glass unit, a layer of granules is placed in the frame to absorb it.

There are several types of distance frames:

• aluminum;
• steel;
• plastic.

The latter, in turn, are of different types:

• thermoplastic frames (TPS);
• Swingle Strip;
• Super Spacer.

Aluminum is considered the coldest, followed by steel, and plastic spacers are the warmest. For example, the Super Spacer product retains 80% more heat than its aluminum counterpart.

To improve the functionality of the double-glazed window, the air chambers of some models are equipped with decorative devices. Usually these are interlacing curtains, roller blinds, and blinds.

In this case, the smallest permissible thickness of the chamber should be 20 millimeters. The components are not serviceable due to the nature of the glass block design. They are controlled either manually using handles or by an electric (magnetic) drive.

Types of glass used

An ordinary buyer without special skill will not be able to determine the type of glass in the window system that he is going to buy. Visually, they are very similar, so we can only hope for the integrity of the manufacturing company, which declares this or that type of material in the accompanying documents.

We list their main types:

• Energy efficient. A thin layer of silver and titanium oxides is sprayed onto the surface of the glass, the particles of which can only be seen under a microscope. Silver plating reflects the flow of thermal energy. There are K and I models. It is the latter that are used more often, since their production is simpler and they have more positive properties. If energy-efficient I-glass is installed on the inside (facing the room) of the window unit, then it reflects heat from the room inside, and during the cold season the apartment will be noticeably warmer. If it is installed on the outside (facing the street), the heat from the sun’s rays does not penetrate inside, and in hot weather the room will be cooler.

The ideal solution: assemble a two-chamber thermal package from two i-glasses and one regular one in the middle.

You can check such glass by holding a flame from a candle or lighter. The reflection will be double, the second should be dimmer than the first.

• Multifunctional. During production, metal molecules are applied to their surface crosswise and in several layers. This allows infrared radiation to be reflected both externally and internally. Therefore, in winter it will be 80% warmer than with ordinary glass, and in summer there will be no greenhouse effect, and you can save energy on cooling the room. The disadvantage is lower light transmittance (by 20%).
• Sun protection. When apartment windows are exposed to direct sunlight in summer, the air in the room quickly heats up. You can prevent this by installing tinted double-glazed windows. A thin film is glued to the surface of the glass, which creates the declared effect by absorbing sunlight.
• Laminated (armored). Such models are made using the technology for manufacturing car windshields: a sample consists of several thin layers glued together. This manufacturing method provides high strength glass blocks that can withstand significant mechanical shocks. In the event of destruction, the canvas does not fall apart into many sharp parts, but is covered with a network of cracks. In addition, these models provide a high level of sound insulation.
• Hardened (stalinite). As a result of special heat treatment, stalinite receives a safety margin six to seven times greater than that of untreated glass. Able to withstand significant mechanical shocks; when destroyed, sharp parts are not formed.
• Reinforced. When reinforcing, metal or transparent is used plastic mesh. This glass has a high level of safety and strength. Improves anti-vandal and anti-burglary properties of windows.

• Self-cleaning. On outer surface The glass is sprayed with a layer of a special substance that prevents dirt from accumulating. At the same time, the window block always maintains a high level of light transmittance.

Almost all types are made on the basis of float glass, which are cast sheets. They are cast at a temperature of 1000 degrees and have an almost perfectly smooth surface.

Dimensions of double-glazed windows

The widely popular window units use sheet glass of various types, the thickness of which ranges from 3 to 6 millimeters. It is irrational to use thicker ones in residential buildings. Sheets with a thickness of 8, 10, 12 millimeters are cast according to special orders and are used in buildings with non-traditional architectural solutions or at special-purpose facilities. About 90% of all double-glazed windows produced are 24, 26, 32 millimeters thick. With such standardization, it is easy to find a replacement for a broken block.

The physical properties of glass impose some restrictions on the dimensions and proportions of structures made from this material. The side length of the glass block should not be less than 300 millimeters, and the maximum possible proportions are five to one. For a double-glazed window with one chamber, where the glass thickness is 4 millimeters, the largest allowable area is 3 square meters. If the thickness is 5 millimeters, the permissible area is 4.2 square meters.

Depending on the location of the apartment, as well as local climatic conditions, the number of cameras in the glass block is selected. Almost always the choice is between one or two chambers; such samples fully satisfy all the requirements for thermal insulation.

There are window systems with three or four chambers in a glass block, but they are too heavy (some up to 100 kilograms). Significant weight makes operation difficult and quickly damages the fittings. If, when installing a single- or double-glazed window, there remains a need for additional thermal or sound insulation, then there are alternative methods for these purposes.

Sealing of double-glazed windows

In order for the air chamber of the glass block of the window to maintain high thermal insulation properties, and the glass to remain transparent, a two-layer seal is performed along its perimeter (edges). The first layer is a non-hardening, viscous, butyl-based composition that protects the chamber from contact with the external environment.

The sealant is not affected by thermal deformation; the spacer perforated frame slides over the glass without damaging it. The second (upper) layer is a hardening, viscous-flowing composition on a polymer base, which, due to its elastic properties, maintains the tightness of the glass unit during thermal deformations.

Filling the air chambers

The main requirements for a window system, in addition to light transmittance and the ability to ventilate rooms, are good thermal insulation and sound insulation. The level of these parameters largely depends on the contents of the glass block chamber. Initially, companies producing metal-plastic windows pumped dry air into the glass unit, the properties of which met the requirements for the level of thermal insulation and sound insulation. However, there are more efficient gas mixtures. It's about about noble gases: krypton and argon. They are colorless, odorless, have low thermal conductivity, and a high ability to absorb sound waves.

If we compare the performance of the air mixture and the indicated inert gases, it turns out that the thermal conductivity of argon is lower by a third, and krypton – by two thirds. Many specialized brands are gradually abandoning pumping air into the chambers of the glass block and using more efficient inert gases.

Purpose of the spacer frame

In order not to reduce the level of all declared properties and characteristics, the design of a plastic window must maintain constant geometric parameters. A significant role in fulfilling this condition is played by the spacer between the sheets of glass, called the spacer frame. This part has a dual purpose:

• First: it guarantees the constancy of the thickness of the air chamber of the glass unit, that is, the gap between the glasses.
• Second: the spacer frame is filled with moisture-absorbing granules. To communicate between the moisture-absorbing layer and the gas filling of the chamber, the surface of the frame is perforated. This system prevents the glass from freezing or fogging up.

In most cases, the width of the spacer frame is from 10 to 16 millimeters, the maximum permissible dimensions are from 6 to 24 millimeters.

If the dimensions of the gasket described do not fit into the permitted range, then a noticeable increase in the thermal conductivity of the glass unit and disruption of the original shape of the glass is possible.

Typically the gasket is made of metal: aluminum alloy, zinc coated steel or high alloy steel (stainless steel). Its thermal conductivity coefficient is lower than that of other metals used, but stainless steel frames are more expensive and heavier.

The disadvantage of metal gaskets is their higher thermal conductivity compared to the same gas parameter in the chamber of a glass block. This difference slightly reduces the thermal insulation efficiency of the window unit. Some companies, in order to mitigate the disadvantage, make spacer frames from polymer materials.

Performance characteristics of double-glazed windows

Metal-plastic windows differ in many ways from their archaic wooden counterparts; one of the main advantages is the versatility of the glass block, its complex design.

A double-glazed window is characterized by many parameters. The main ones:

• Thermal conductivity. 80% of the window system area is made up of glass block. Therefore, if you put a thin double-glazed window into a frame with even five or six cameras, the overall energy efficiency of the window system will be very low. In a high-quality design, the heat transfer resistance of all components should be equally high. To achieve maximum values ​​of this indicator for a glass block, there are three methods: increase the number of chambers, replace the air in them with a more efficient gas mixture, and also apply a special coating to the glass. Each of these methods has advantages and disadvantages, and a good sample should strike a balance between the different methods. For example: the more cameras, the higher the weight of the structure, which means its operation becomes more complicated, and the price increases significantly. A more effective and promising method of reducing the thermal conductivity of a window system is the injection of inert gases into the chamber, as well as a special glass coating (silver and titanium oxide). The combined use of such techniques increases the energy efficiency of the window by up to 70%.

• Sound insulation. To improve this parameter, three methods are usually used. First: pumping inert gas (argon, krypton) into the chamber, which increases sound insulation by 10%. Second: increasing the dimensions of the spacer frame; every two millimeters of the width of this spacer increases sound insulation by 10%. Third: installation of acoustic films on glass and installation of triplex on the outer contour of the double-glazed window.

• Safety. For all its advantages, glass has significant disadvantages - fragility, the appearance of fragments when it is destroyed. Three methods are also used to increase strength. First: the use of stalinite, its hardness is five to seven times higher than conventional samples. Heat treatment does not deteriorate other characteristics of the material, such as light transmittance, thermal conductivity, sound insulation level, etc. Second: the use of the triplex method, when the glass consists of several thin sheets glued together, alternating with a transparent polymer film. When destroyed, such a sample does not break up into fragments, since they are held in place by the film. Third: reinforcement; a mesh of polymer or metal is used as a reinforcing layer.

• Sun protection properties. To neutralize the unwanted effects of direct ultraviolet rays, you can use mirrored or tinted glass, which absorb and reflect about half of the solar radiation.

Signs of poor quality glass

Only a specialist can reliably determine the quality of a glass block of a window system. However, there are a number of signs indicating questionable quality of the product, which can be seen without special skills:

• Marking designation. It includes the company's trademark, release date, and information about components. If there is no marking, then this is grounds for suspicion of the dubious origin of the product.
• Integrity and transparency of the glass surface. During inspection, no chips, cracks, etc. should be found. Condensation cannot accumulate inside the bag.
• Quality of sealing: assumes that the spacer frame is free of traces and fragments of mastic, and the top polymer layer applied along the outer perimeter of the glass block is uniform, without bumps or cracks. If the sealing is carried out carelessly, it is better to refuse the purchase.
• Compliance with proportions and dimensions. You should use a tape measure to measure the glass diagonally, and if the lengths differ by 3 millimeters or more, then the geometry of the block is not consistent. Using a caliper, you can measure the thickness of the block at different points, the maximum tolerance is 1 millimeter.

Attentiveness and a couple of basic measuring tools will help determine how high-quality the window is. If any of the listed signs of dishonest work are detected, the product cannot be purchased, even if its price is low.

Number of seal circuits

One of the main advantages of metal-plastic window systems over traditional wooden ones is their tightness. To achieve it and maintain it throughout the entire period of operation, sealing contours are used that do not allow cold air in winter and moisture in summer, keeping the room warm. They also contribute to achieving a given level of sound insulation.

The seal is pressed into the grooves of the profile along the entire perimeter. There are models with two as well as three sealing circuits. The first option: one circuit is installed on the street side, the other in the apartment along the perimeter of the doors. Second option: to the two indicated, another row of the sealing element is added, the third contour is laid in the middle of the fold of the sashes. Models of the second option, of course, are more expensive.

Based on the location of the sealing contours, plastic windows are divided into three categories:

• One inside, one outside. This type is the most popular; most companies choose it. The internal element retains its declared properties longer, since it is not subject to destructive influences environment. The outer element gradually loses its integrity and original properties, moisture penetrates inside the window block. However, due to the specific geometry of the window, water is drained through holes in the profile. Disadvantages: if the external seal loses its declared qualities, the thermal insulation properties of the entire system are significantly reduced. Due to moisture penetration, the fittings rust and fail.

• One inside, the second in the middle of the fold of the sashes. A more reliable option than the previous one. The outer element is located outside the area of ​​direct exposure to the environment, so it retains its properties longer. The specificity of its location protects the fittings from the ingress of water, which is drained through drainage systems. Another advantage of this option: the wind presses the outer element against the stop, increasing the tightness of the system.

• One inside, the second in the middle of the fold of the sashes, the third outside. The middle element forms a pair of air chambers, the first collects and removes moisture, the other contains fittings that are not exposed to water.

Expert opinion

Anton Tsugunov

Construction expert. Entrepreneur. 15 years of experience. More than 100 completed objects.

Does it make sense to overpay for enhanced sealing of the window unit?
This option has a slight effect on the cost of the window. Thanks to the triple seal, the service life of the fittings is significantly extended, the thermal circuit retains its declared properties longer, and the level of thermal and sound insulation increases.

Types of sealant, requirements for it

Basic requirements for sealing material: strength, elasticity, preservation of the declared properties during thermal changes, safety for health, color fastness throughout the entire period of operation.

The most common types of seals are:

• . Advantages: change shape when compressed, suitable for automatic assembly of a window block, easy to weld, inexpensive, can be replaced by the user without special skills. Disadvantages: at extreme temperatures and constant exposure to the sun's rays they quickly deteriorate.

• . Advantages: wear resistance, not afraid of extreme temperatures and environmental influences. Disadvantages: high cost, not always available in retail.

• . Advantages: wear resistance, not afraid of extreme temperatures and environmental influences, cheaper than silicone sealant. Disadvantages: you need to call a specialist to replace it.

• . Advantages: the same as silicone or EPDM, plus low price and the ability to replace it yourself. Disadvantages: Extreme temperatures and constant exposure to the sun's rays degrade.

• . Advantages: quickly restore shape after compression, are not afraid of extreme temperatures, as well as environmental influences, high level of thermal and sound insulation, retain color throughout the entire period of operation. Disadvantages: if the integrity of the shell is damaged, they lose their properties, you need to call a specialist to replace them, high cost.

In order for the sealing material to last as long as possible, it should be cleaned and lubricated a couple of times a year (before summer and winter). To do this, you cannot use solvents; it is better to wash the seal with water and a neutral detergent. When it dries, lubricate it with glycerin or silicone oil.

Glazing beads: purpose, types

The function of glazing beads in metal-plastic windows is to secure the glass block in the frame. In addition, this detail contributes to a high level of sealing, as well as thermal and sound insulation of the entire window system. For its installation, a landing groove is provided in the profile. The bead is a long strip of polyvinyl chloride, equipped with a rubber seal. Over time it wears out and the beads have to be replaced. This process is simple and does not require special skills. In order not to disturb the style of the window unit, the new slats must match the frame in color.

The described components are classified according to the shape of the profile section: it can be square, round, or figured. For window systems with one camera, wide beads are used, with three - narrow, with four - reinforced. In stores you can find the described parts not only made of polyvinyl chloride, but also of glass composite, which are identical in properties to their PVC counterparts.

Accessories: characteristics, types, popular brands

Such important parameters of the window system as thermal and sound insulation and light transmittance depend on the frame and glass block. performs no less important functions; the comfort of using the entire system and service life depend on its quality. Fittings are not only a set of devices (hinges, latches, handles), but also a well-coordinated mechanism responsible for opening and closing the doors in all positions, air exchange, and sealing.

The fittings are installed around the entire perimeter of the frame. Its main types:

• Turning. Similar to the mechanism used in wooden window systems, the sashes rotate around axes in a vertical plane.
• Sliding. The frame moves in the plane of the opening. This mechanism is suitable for large-area window systems, for glazing balconies and loggias.
• Folding. Rotation of the valves is possible along horizontal axes, the rotation angle is 180 degrees. To comply with this parameter, a special limiter is installed. The transoms can be tilted down and up.
• Universal. The most complex sample: the doors rotate around axes in a vertical plane, and also recline along horizontal axes with the lower edge fixed. One of the options is selected by moving the handle to a specified position.

The permissible design load on the fitting mechanisms ranges from 50 to 135 kilograms. This is enough for window units installed in many apartments. Conventional, relatively inexpensive equipment, which is installed in most popular windows, should theoretically smoothly work out 10 thousand consecutive manipulations (closing, opening, ventilation mode, etc.). Expensive mechanisms produced by famous brands are designed for 50 thousand consecutive actions. All fittings must be made of alloy steel. Use less than durable metals only for components not subject to stress. The use of plastic in the mechanism is unacceptable.

If these rules are not followed, then there is no doubt that such accessories are a low-quality fake.

The most famous specialized companies: Siegenia-Aubi, Maco, Winkhaus, Roto, GU (Gretsch-Unitas).

Accessories for fittings

The described mechanism consists of many devices and parts that provide ease of use of the window system, here are the main ones:

• . Installed along the inside of the frame perimeter, purpose: to ensure tight closure of the sash. The minimum quantity of these parts is four units. If there are fewer of them, the tightness will be broken and the thermal insulation properties of the window will decrease.

• Locking device. The device protects the mechanism from damage due to incorrect actions and contributes to a high level of safety in using the window unit. You can check its presence like this: move the open sash to the folding position with the handle, if the transom hangs only on the lower hinges, there is no locking device.

• . There are the following: hidden (opening angle 100 degrees), screw-in (mounted on threaded pins), overhead. Parts of the overhead type are collapsible, non-dismountable, tilt-and-turn, rotary, and with increased security (against burglary). In the fitting mechanism, hinges are conventionally divided into samples of the lower or upper group.

• . High-quality models are made of aluminum alloy or brass, covered with plastic on the outside. Cheap, made of plastic, they break quickly. There are increased security handles (anti-burglary), they are equipped with a locking device that prevents the door from opening from the outside. Based on their shape, they are divided into curly and flat. The highest quality products are from the Roto and Maco brands.

• . These nodes provide displacement locking device in the corners, turning the sash into a tilt-and-turn state, they consist of steel plates.

• . These fittings protect the window unit from unauthorized opening. The trunnions are installed together with the bars (reciprocal, locking), do not require adjustments (automatically adjusted depending on the rebate play), and ensure smooth operation of the locking device.

• . These elements must ensure all manipulations with the window (closing, opening, tilting). There are three types: main, intermediate, auxiliary. The auxiliary ones are located near the hinges and are responsible for the tight narthex of the frame. The main ones depend on the type of fitting mechanism. As a rule, auxiliary ones are various anti-burglary locks.

If, when using a window system, a backlash appears in the operation of the locking fittings or, conversely, the movement of the mechanism is difficult, it means that it needs adjustment. If you do not have special skills, it is better to call a specialist to make adjustments.

Slopes and ebbs

The installation of the window unit is completed. These are fragments of the opening framing the window along the perimeter from the street and apartment sides. Their decoration plays a rational and aesthetic role.

• Rational: the level of thermal insulation increases, as well as the service life of the entire system.
• Aesthetic: a window with trim on slopes looks beautiful.

There are several finishing options: plaster, plasterboard, plastic sandwich panels. Plastering slopes is used, as a rule, in public or industrial buildings. Advantages: wear resistance, versatility, simplicity of the process, low price. Main disadvantage: low level of thermal insulation.

Slopes made of plasterboard, which is laid on a layer, are in demand. thermal insulation material, then the surface is primed and coated construction staff, paints. The advantages of this finish include a high level of thermal insulation and a long service life. Disadvantages: complex, time-consuming installation, can only be used from the side of the room.

The most rational option for treating slopes is to install plastic sandwich panels. This building material repels moisture, is impervious to steam, is characterized by a high level of thermal insulation, and does not develop fungus or mold. You can also add quick, simple installation, versatility, and a long service life to the advantages. There is only one drawback: the relatively high cost.

Joints of adjacent slopes should be sealed liquid plastic, which is similar in composition to PVC, while the integrity and shape of the butt seams are not compromised throughout the entire period of operation. Silicone cannot be used for these purposes, since it will not protect the slopes from mold; after a few weeks, the integrity of the seams will be compromised, and everything will have to be redone.

The flashing is mounted in the lower part of the opening from the street side, it is a sheet with a curved edge, made of plastic or iron, of different dimensions. In addition to its decorative purpose, this finishing detail protects the wall, as well as the window, from the influence of the external environment, and drains melt or rain water.

In order for the ebb to perform the listed tasks, it is important to follow the installation rules:

• The sheet is installed at an angle towards the street.
• The ebb is inserted into the groove under the window and screwed to the stand profile, but not to the front part of the window!
• There should be no gaps between it and the wall.

Most often, the casting is made from thin (thickness from 0.5 to 1 millimeter) rolled steel. The workpiece is coated with layers of white zinc, polymer, and varnish, this contributes to a long period of operation. The dimensions of the workpiece depend on the window opening, standard width(reach) is 14, 18, 25, 45 centimeters.

To soundproof the ebb, its reverse (bottom) side is covered with a layer of material that absorbs vibrations. And the ebb itself is additionally glued to the mounting foam.

Additional features of PVC windows

The popularity of plastic window systems is explained not only by their characteristics and stylish appearance, but also by their versatility. The main functions have already been described in this article; we list some additional ones:

• Mosquito sections. It is a plastic frame with a polyester mesh of different capacity. Purpose: when the window sashes are open, prevent insects, fluff, and dust from entering the room. It is fixed in the frame on special mounting angles or pressed with metal brackets.

There are also magnetic, Velcro and roll nets. The latter are very comfortable, do not require removal, just lift them up like roller blinds. The downside is the high price and difficulty in maintaining cleanliness. Frame Mosquito nets You can always easily remove it, wash it and put it on the balcony or in the pantry.

• For cat owners, there are samples with reinforced mesh that maintains integrity after contact with the animal’s claws.

• Ventilation valve. Mounted in the upper sector of the window profile, purpose: automatic air exchange that does not require opening the sashes. Advantages: the ability to adjust the air exchange rate, the device is easy to clean with a vacuum cleaner, there is no noise during operation, there is no need to connect it to an electric current network. There are models (recuperators) that, due to their design features, use the thermal energy of the exhaust air mass to heat the supply air mass.

• Devices for adjustable air exchange: comb, rotation limiter, lock for stepwise tilt of the sash. The restrictive comb is designed to fix the window sash, while ensuring ventilation of the room in the specified mode. The width of the gap between the sash and the frame ranges from 1 to 7 centimeters. The comb will not allow small children or pets to open the window wider, which is an additional safety measure.

• The rotation limiter secures the sash at a distance of 6 to 8 centimeters from the frame; this gap is enough for the influx of fresh air mass. The lock for stepwise tilt of the sash works in a similar way.

• Slit ventilation. An air exchange mode in which air flows from the street through a gap (4-5 millimeters wide) in the upper sector of the window. The gap is formed when the handle is turned 45 degrees upward.

• This function is also called “winter ventilation”, since it does not create drafts and significant heat loss.

• Child protection. Child locks do not allow the child to open the door wider. The most commonly used devices are those that block the rotation of transoms; The handles are removable and lockable with a key.

Companies producing plastic translucent systems are constantly improving their design, so the number additional options will grow.

Window sills for metal-plastic windows

In addition to decorative ones, they have many practical purposes. For example: a shelf for pots of plants, a place for a child to play, a sitting area for a cat, an additional countertop in the kitchen for storing utensils or household appliances. Specialized companies produce samples from different materials, colors, dimensions. Window sills made of PVC, chipboard or MDF, stone (natural, artificial), and wood are in demand.

• Stone ones are environmentally safe, durable, and can withstand heavy loads. Disadvantages include significant cost and weight.
• Wooden window sills, again, are environmentally safe, beautiful, and pleasant to the touch. However, they have many disadvantages: rapid wear, high cost (especially if made from valuable wood), and they are afraid of condensation.
• Options made from MDF or chipboard are not exposed to moisture, temperature changes, ultraviolet radiation, and are cheap. Disadvantages: low level of strength, presence of different chemical compositions (glue, resin, etc.).
• PVC window sills have almost no drawbacks, except that we can mention that they are made from non-natural material. There are many advantages: they are not afraid of moisture, temperature changes, ultraviolet rays, cheap, durable, high level of thermal insulation, easy to clean. They withstand significant loads, the magnitude of which depends on the number of stiffeners.

– this is not the type of work that can be done without special skills, equipment and materials. For installation, you should hire specialists from a specialized company that has been working in this field for a long time. A competent master will observe all the nuances of the installation technology: a standard protrusion from 5 to 10 centimeters long, the angle of inclination of the window sill plane, etc. Such work requires skill in using certain building mixtures, adhesives, polyurethane foam, and hardware.

Options for window system models

The block can consist of one leaf or several. There are four standard models of metal-plastic windows from which blocks are formed:

• Deaf. There is no opening sash, simple design, the cheapest sample. They are used in corridors of public buildings or in rooms where openings are located too high.
• Rotary. The opening sash rotates around its axis in a vertical plane. There are no restrictions on use; they can be used anywhere.
• Folding. The sash opens partially in the upper sector of the window, located at an angle to the plane of the frame. They are installed in sanitary facilities, bathhouses, and entrances of apartment buildings.
• Tilt-and-turn. The most convenient model, the transom opens as in the rotary and tilting models, the option is selected by turning the handle. There are no restrictions on use; they can be used anywhere.

HELPFUL INFORMATION: What types of electrical outlets are there?

The number of opening options in the block, as well as their type, depend on the characteristics of the room; one system may include fixed, turning, and tilting windows.

Production

Some companies that produce translucent PVC structures own the full production cycle, while others assemble blocks from purchased components. The first group includes large companies that have been operating in the core market for a long time. Owning the full cycle, they control the quality of the product at all stages of its production. Large companies also invest significant money in innovative developments.

Using this business model, they produce the highest quality window systems in compliance with all norms and standards. The second category includes newcomers or companies that are initially focused only on assembly. Some are trying to reduce as much as possible production costs, while purchasing low-quality components.

Companies producing translucent PVC structures are required to have certificates of conformity, such as RAL and DIN EN ISO 9001:2000.

Both the brands themselves and third-party companies install metal-plastic windows.

PVC profiles are made by extrusion; the raw materials include polyvinyl chloride granules, stabilizing and modifying elements, titanium oxide, dyes, etc. PVC granules are produced almost all over the world. PVC blanks are made using extruders. Before turning into a part for a metal-plastic window, they are processed on many machines. Equipment used: milling cutters, miter saws, drilling and reinforcing machines, clamps, welding machines, etc.

The impact of PVC windows on health and the environment

The development of global industry over the past 150 years has led to significant damage to the ecosystems of our planet. Therefore, safety for health and nature of any product produced by production methods is one of the most important parameters. Polyvinyl chloride is an unnatural material obtained by chemical synthesis. However, it is not dangerous to health, this is confirmed by many independent examinations conducted by research centers around the world. Of particular concern were some additives that provide PVC blanks with the declared qualities, but new technologies completely neutralize the possible harmful effects of these additives.

Environmentalists were also concerned about the presence of lead in the profile and adhesive composition, which was used to attach the laminating film. Older models used lead to prevent the blanks from losing their original color; moreover, these were passive lead compounds that do not pose a threat to the environment. New models no longer contain lead; it has been replaced with zinc and calcium compounds. They also use safe polyurethane adhesive.

The problem of plastic recycling is acute, but it mainly concerns plastic containers and packaging. There are two methods for recycling used PVC profiles.

• First: using it as an unconventional raw material for generating electrical energy (pyrolysis method). The specificity of the process eliminates toxic emissions into the surrounding ecosystem.
• Second: recycling the old profile into raw materials for the new one. Translucent PVC structures are designed to last for half a century, so gradually there will be more methods for their effective recycling.

Summarizing the above facts, we can conclude: metal-plastic windows are safe.

The quality and long period of uninterrupted operation of a window system depend on two components: the properties of the window itself and compliance with installation technology. The stores offer products from the EU, China, Turkey; the best plastic windows are made by well-known European companies, especially German ones. European analogues are more expensive than others, but not dramatically; such windows, if the operating rules are followed, will last 40-50 years.

Expert opinion

Anton Tsugunov

Construction expert. Entrepreneur. 15 years of experience. More than 100 completed objects.

Installation is an equally important component. According to statistics, 80% of problem situations when using PVC windows are a consequence of violations of installation technology. It is best to order the installation from a branch of a well-known European company that owns the full production cycle. Such a contractor always carries out the installation efficiently, draws up the relevant documents, and issues a warranty card for the use of the window.

If it is not possible to order installation services from a European manufacturer, then you should choose a third-party contractor with a good reputation. Information of this kind is available on the Internet, you can easily find out: how long this company has been operating, what are the customer reviews, what are the guarantees, etc. It is better not to contact a contractor who is little known or offers too low prices. Even if the installation is done by a reputable company, it is still worth monitoring the progress of the work.

Installers must use a special construction foam composition (for example, “Tytan”). To dry and protect the foam layer from ultraviolet radiation, a special sealing tape (PSUL) must be used. It is hidden from the sun's rays by external slopes or coverings.

Which windows are better to install in an apartment (by room)

Here are some more tips for installing different window systems in rooms of an apartment for various purposes (recommendations are calculated for the average European climate):

• For the living room, a four- or five-chamber profile with a glass block with one or two chambers is suitable. Filling the chambers with air will be enough; it is not necessary to overpay for models with inert gas. You can also refuse energy-efficient glass.
• The office has to be ventilated frequently, and sound insulation is also important for the workplace. Therefore, a profile with five chambers is suitable for it, a glass block with two or three. Due to frequent ventilation, a high-quality fitting mechanism is important.
• The children's room and bedroom should be warm; the same windows as in the office are suitable, but you can choose models with inert gas in the double-glazed window and energy-efficient glass.
• The kitchen does not require a high level of sound or thermal insulation, so a profile with three chambers is suitable for it, a glass block with one or two. Due to frequent ventilation, a high-quality fitting mechanism is necessary; you can also install a ventilation valve.

Features of winter installation, removal of construction waste

There is an opinion that replacing windows should only be done in spring or summer, but this is nothing more than a myth. Replacement is possible in winter, it just has a number of features, although there are still temperature restrictions.

• The minimum temperature at which such work is allowed is 15 degrees below zero. At lower values ​​it loses its properties polyurethane foam, the rubber sealing materials become tanned, making it impossible to adjust the sashes.
• The window unit cannot be installed “from wheels”; it should be brought into the apartment a day before installation, this will eliminate thermal deformation of the window components.
• When replacing, foam sealing compounds of a special frost-resistant type are used.
• Among the equipment there must be a “heat gun”, which is used to heat joints with foam from the outside, waterproofing tapes, as well as PSUL. To avoid cooling the room, you can use a heat shield during installation.

You cannot place old windows and bags of construction waste near trash cans in the yard; you can get a fine for this.

The waste along with the dismantled frames should be taken to the city waste disposal site. When concluding an agreement with a company, it is better to include this item in the mandatory list of works and pay for it. All major contractors provide similar services. Alternative option: Call a small company specializing in transportation; they usually provide similar services.

The principle of operation and design of plastic windows

Plastic windows are not new on the market in Russia for a long time. They have been successfully replacing conventional wooden frames with glass for many years and are in demand because they are reasonably priced, reliable, functional, durable and very convenient. They are installed in both apartments and offices. However, the great popularity of the product has led to the fact that now a lot of manufacturing companies have appeared on the market, and not all of them produce good products. Therefore, it is important to know how to choose the right windows, so as not to be disappointed later and regret the money spent.

When choosing a window, you need to take into account all the parameters. So, first of all you need to pay attention to the profile. This is exactly the basis of frames and sashes. Any profile is a special and complex structure made of plastic and aluminum (maybe steel), the full complexity of which can only be appreciated if you cut the profile and see what is inside it. Each profile has several cavities, and between them there are sealed partitions. By the way, it is these cavities that are called window chambers - they make it warmer due to the emptiness that does not allow air to pass through.

On a note! The more cameras there are at the window, the warmer the windows will be.

Any profile is produced according to certain standards. In Russia this is GOST 30673-99. There is also a European version - EN 12608 SR. All profiles can be divided into three types depending on the thickness of the partitions and walls.

Table. Three profile types.

The metal inside each window is an amplifier that allows you to achieve required rigidity and strength. It is not visible from the outside, but its importance is great.

When looking at the window, the buyer will see only plastic - PVC. It is artificial, but still a good material and not hazardous to health. It has a low price, does not conduct heat well, is environmentally friendly, paints well, is durable (if it is good), and does not allow sounds to pass through. In a word, perfect option for a window system.

On a note! From an aesthetic point of view, PVC is superior to standard wooden windows, which dry out over time and the paint on them peels off.

By the way, the width of the profile also matters. In another way, and in professional slang, it is called mounting depth. For a conventional window system, it is 0.5-0.8 cm. Moreover, if the width of the frame can be only 0.6 mm, then there will be three chambers inside. There are four, five-chamber, and even six-chamber windows. The wider and more powerful the windows, the higher quality fittings and thicker double-glazed windows can be used. Also, a deeper window usually turns out to be warmer, since the chambers in it have a larger volume.

All about double glazed windows

A double-glazed window is also one of the main elements of any window. This is the same transparent glass that allows light to pass through and allows you to see what is outside the window. It is responsible for a good level of protection from street noise, from the cold, and for good lighting.

On a note! The first double-glazed window appeared about 100 years ago.

A double-glazed window can easily replace double window frames. It consists of two sheets of float glass connected to each other (created using the technology of pouring molten glass), and between them there is a special gasket, thanks to which there is a certain space between the glasses. It prevents any sounds or cold from penetrating into the room. The window remains transparent. The glass itself can have a thickness from 3 to 12 mm. For windows in an apartment, a thickness of no more than 5 mm is sufficient.

The described option is a single-chamber double-glazed window. But if three or more glasses are connected, and there are cameras between them, then there can be 2, 3-chamber double-glazed windows. The more of them, the warmer it will be in the house, but the light will penetrate a little worse. The thickness of the glass unit can be 24, 26 or 32 mm. The choice of type and size will depend on the choice of window profile.

The glass unit is sealed, inside it there is dry air or a special inert gas (for example, argon). Good windows should not fog up when the temperature changes. Windows with argon are more expensive.

Advice! You can select a package based on the labeling. So, SPD is a two-chamber version, SPO is a single-chamber version.

By the way, glass may have certain characteristics. For example, it can be sprayed, tinted, impact resistant, matte, and so on. Here you need to take into account your preferences and budget.

A special metal gasket is installed between the sheets. It allows the package to maintain its exact dimensions and correct shape. Usually the frame is also made of aluminum or steel. This is the source of the appearance of cold bridges. Its width varies between 6-24 mm.

The frame is also needed to absorb moisture, for this it has perforations, and in the cavity inside there is an absorbent substance that absorbs moisture. That's why windows don't fog up from the inside.

The glass unit must be sealed. Otherwise, it will not retain heat well. Inside, a butyl substance is used for sealing, which is applied to the area of ​​​​the edges between the glass and the frame. This sealant does not harden and is not afraid of temperature fluctuations. Its outer layer is a solid polymer substance such as epoxy or silicone.

Selecting a seal

The seal also helps to achieve tightness and good heat retention. It is located around the perimeter of all the doors, preventing moisture, noise from the street and cold from entering the house. So, if possible, it is better to choose a good seal option. It must be strong, durable, elastic, heat-resistant, and not emit unpleasant odors.

Table. Types of seals.

View	Description
TRE	This is the designation of thermoplastic, the most common option, since it is most often installed during automatic window assembly. It is elastic, easily compressed by the doors, and seals joints well. However, frost or hot weather has a negative effect on it, as the material softens too much or becomes brittle. If the windows have such a seal, during extreme conditions It is not recommended to open and close the doors frequently. In this case, the material will last a very long time. In extreme cases, it can be easily replaced with a new one.
EPDM	Rubber seal, which is characterized by increased resistance to a number of influences. Costs less than silicone material. Usually installed on more or less expensive windows. It is not suitable for independent replacement - everything is too complicated.
Silicone	This is the most reliable option and the most durable. It does not wear out, is not afraid of temperature changes, or the influence of a number of other factors. But its price is high, and to replace it yourself you still need to manage to find new seals.
Rubber	A good seal that has a reasonable price. But the soft version of the rubber is short-lived and will quickly require replacement, which, by the way, is easily feasible.

Advice! Any seal, no matter how high quality it is, still needs to be changed after some time. Usually it’s easy to do it yourself, without calling a specialist. You can also try to extend the service life of already installed seals: try to handle windows carefully, do not use them often in frost or heat, clean the seal twice a year, lubricating it with silicone oil or glycerin. You only need to wash with clean water.

About accessories

The functionality and ease of use of any window depend on good fittings. By the way, how high quality it is can often be understood by its appearance. These are not just locks and hinges, but also a system for protecting the window from burglary, sealing it and pressing it. Good fittings should be made of high quality steel. Sometimes elements that do not experience severe loads can be made of alloys.

Almost any plastic window sashes can be opened at different angles or set for micro-ventilation with just the movement of a handle. No windows are needed to easily ventilate the room, so there is no cluttering of windows with unnecessary elements. But the entire window control system PVC sashes quite complicated.

All the fittings of a plastic window surround it in a circle and are well fixed inside and on the sashes in special grooves. All elements must be correctly adjusted and configured for the window to work well and for a long time. Window fittings include groups of hinges, a locking mechanism and handle, and switches for the direction of movement of the sashes. The structure also contains special combs and tapes that transmit force from the human hand to other elements. Usually the fittings are installed immediately at the factory; the craftsmen only adjust them when installing the profiles.

Table. Types of window fittings.

Type	Description
Turning	The usual option, the same as for wooden windows. The plastic frame simply opens and closes along a vertical axis. The fittings can be installed on the left or right side of the frame.
Folding	Such a sash can open 180 degrees along the horizontal axis. It can be opened up or down - it depends on where the mechanism is installed. Usually there is also an element that limits the angle of rotation.
Tilt&Turn	This is the option that can mostly be found on plastic windows. It allows you to open and partially open the window vertically and horizontally. With such a window you can use the micro-ventilation function. The control is carried out using the sash handle. The most convenient and most complex type of fittings.
Sliding	Such a sash can move along the plane of the window. Sometimes you can find them on the doors of loggias. There is another option - tilt-and-slide. Such windows can be moved or opened slightly at the top for ventilation.

The plastic window sashes are quite heavy. Only good fittings can withstand such a load and last the stated period. Its usual version can withstand a load of 50-130 kg. For home - the best option. Good and expensive fittings can withstand about 60 thousand opening and closing cycles. As a rule, the manufacturer gives a 10-year warranty on it. Cheaper fittings will withstand up to 10 thousand cycles.

On a note! You can adjust the fittings yourself. All actions are performed using a hex key. But without some experience, it is better not to take on the matter yourself, but to call a specialist.

How to choose the right plastic windows

To choose good plastic windows, you need to take into account a lot of things: from who the manufacturer is to the supplier and installer. Let us outline the main parameters that you need to pay attention to when choosing the windows themselves.

First of all, you need to choose a manufacturer. Much, if not everything, may depend on this. So, it is better to give preference to proven companies rather than new unknown brands. The first ones protect their reputation. However, due to high competition in the market, even newly existing companies will try to sell good windows, otherwise they simply will not survive with a damaged reputation.

First, it’s worth assessing the appearance of the profile itself, namely the plastic from which it is made. It should look uniform in color, and should not be grainy to the touch; the surface should be smooth. Ideally, PVC should not have an unpleasant odor, but some new windows may still have a corresponding odor immediately after installation. If the window smells very strongly, then you cannot buy it. It may be treated with protective substances containing cadmium or lead - they are hazardous to health. All connections on frames and sashes must be of high quality, inconspicuous, and well-fitted.

If you are going to replace window units with old wooden frames Pay attention to the rating of the site Marka.guru - the portal offers you to get acquainted with the best manufacturers of plastic windows. The products of leading companies are of excellent quality; only durable materials that meet all safety requirements are used in the manufacture of products. It is better to choose the most reliable manufacturer of window profiles, and then your home will always be warm, light and cozy.

In modern times, manufacturers of plastic windows regularly improve the quality of their products by introducing new and improved technologies. But still, when purchasing, you should pay attention to some nuances:

1. Appearance. The window is one of the primary attributes in the interior; even the highest quality window with an inappropriate design will look out of place in the interior of the room.
2. Type of design. Windows come in fixed, pivoting and tilt-and-turn types. The tilt-and-turn design is more convenient to use.
3. Number of sashes. The choice depends on the size of the window opening.
4. Number of cameras. The most reliable protection from severe winter frosts - a three-chamber window block design.
5. Quality of fittings. To prevent the doors from warping later, pay attention to the quality of the turning mechanisms.
6. Manufacturer. Give preference to proven, reliable brands.
7. Qualification of a window installer. Even the most reliable and high-quality double-glazed window can be damaged by improper installation. If the master treats his work negligently, in the winter months drafts may pass through the window, the sashes will warp, and moisture will seep in due to insufficient tightness. To avoid this, trust the installation of windows only to trusted companies.
