Plastic profiles for PVC windows: names, reviews, ratings. Comparison of manufacturers of plastic window profiles The best PVC window companies

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 also cause mixed opinions from users, 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?

Metallo plastic profile- this is a frame that can include up to eight cameras, 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. Also common fiberglass covering c The list of main distinguishing features of profiles also includes installation width. 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 according to 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 producers of metal-plastic profiles is the company Proplex. 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, perhaps, can 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. Technical features 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. No toxicity is general condition 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 development technological methods production of profiles and fierce competition are 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 inclusion of PVC connections zinc and calcium.

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.

Reading time: 7 minutes.

The profile is the basis for the manufacture of window frames and sashes. The appearance, durability and reliability of the entire window design.

Classification by materials

For production modern windows Wood, aluminum, and PVC are used for these blocks. Each type of material has its own advantages and disadvantages, features and limitations in use.

Tree

The best and most expensive types of wood for the production of window profiles are oak and larch; alder and pine are also used. Expensive wooden structures is associated not only with the use of natural wood, but also with the features technological process. The material for window profiles needs careful processing (drying, impregnation with antiseptics, painting, varnishing), and during the manufacture of the product high accuracy and skill is key.


Advantages wooden windows:

  • environmental friendliness;
  • good heat-shielding properties;
  • maintaining natural air exchange between indoors and outdoors;
  • aesthetic natural appearance.

Flaws:

  • the possibility of warping and swelling if the production and installation technology is violated;
  • low fire resistance;
  • high price.

Aluminum

Since metal is not capable of retaining heat, aluminum profiles are mainly used for or utility rooms when there is no possibility or need to install warm glazing.


Exist . A special thermal insert is placed in the profile, which provides high thermal insulation properties such window designs.

To the benefits aluminum profiles include:

  • strength and durability;
  • ease;
  • resistance to external influences;
  • fire resistance.

Minuses:

  • low heat-protective properties of the “cold” profile;
  • high price of the “warm” option.

Polyvinyl chloride

Reinforcing U-shaped profile for structural rigidity

PVC profiles have become the most widespread for the production of modern windows, due to their low cost compared to wood and aluminum and excellent thermal insulation and performance properties. The main competitive advantages of PVC:

  • high level of thermal insulation;
  • ease of manufacturing and installation of finished products;
  • high resistance to the influence of precipitation and chemical reagents;
  • the ability to produce products of various designs and shapes;
  • affordable price.

Main disadvantage– flammability, like all plastics. All other user complaints in most cases are related to the choice of low-quality products or installation errors.

Characteristics of PVC profile

The lion's share of all installed window units falls on plastic products. The market offers windows from the profiles of dozens of manufacturers, which at first glance look the same. Often low level quality manifests itself only after some time of operation, when it becomes obvious that the profile does not cope with its functions and does not provide the proper level of thermal protection. When choosing a product, it is useful to know the main significant characteristics of a PVC window profile.

Wall thickness


According to this indicator, 3 product groups are distinguished:

  • Class A. This includes products that have an outer wall thickness of 2.8 mm and an inner wall thickness of 2.5 mm. Such indicators are considered optimal to ensure best thermal insulation living space.
  • Class B. Products with an outer wall thickness of 2.5 mm and an inner wall thickness of 2.0 mm. Such products provide less reliable protection against heat loss and are more susceptible to deformation during operation. The main purpose is installation in shops and public institutions.
  • Class C. Products with thinner walls than in previous classes. Windows made from it are intended for glazing non-residential, warehouse, and industrial premises.

Profile width

The indicator determines which double-glazed window can be mounted in a given profile. A double-glazed window consists of several glasses connected by a frame around the perimeter. The spaces formed between the glasses are filled with ordinary air or inert gases (in premium segment products) to improve thermal insulation performance.


A single-chamber package consists of two glasses and one air chamber between them. A two-chamber glass consists of 3 glasses, between which there are, respectively, 2 chambers, etc. The greater the number of glasses, the warmer the finished product.

Also, the width of the profile determines the installation dimensions for installing the window. As the width increases, the overall weight of the structure increases - this must be taken into account, for example, when glazing a balcony with weak base slabs.


Typically the standard value is 58-80 mm, some brands offer products up to 120 mm wide to produce products designed for use in harsh climatic conditions and characterized by improved sound and heat insulation characteristics.

Number of profile cameras

Not to be confused with the air chambers of a double-glazed window!

The plastic profile is hollow inside and separated by partitions. The thermal insulation properties of PVC profiles are due to the presence of hollow chambers between the lintels - the more of them, the lower the thermal conductivity of the window frame and sash.


Each cavity performs a specific function (moisture removal, fastening of fittings, ensuring strength), and their number (usually 3-8) and location are determined by technological calculations. The most in demand are 3-5-chamber types of plastic profiles.

Metal reinforcement

The plastic profile is additionally reinforced metal frame to add rigidity to the structure. This significantly reduces the likelihood of deformation and sagging of the window sash due to many opening-closing cycles, temperature changes and other influences during use.


The shape of the frame depends on the size of the window:

  • L-shaped– reinforcement is laid along 2 walls; sufficient for small windows;
  • U-shaped– strengthening of 3 walls of the profile; suitable for window sizes up to 1.9 m in height;
  • closed– the reinforcement is located along 4 planes and ensures the greatest rigidity of the product; For glazing large areas of loggias and panoramic balconies, it is recommended to choose this type of profile.

What to look for when choosing

It is difficult for the buyer to determine the quality of the profile on exhibition samples. In most cases, you have to rely on the integrity of the seller and the manufacturer of window structures. There are some features that will help you avoid buying a low-quality product:


When purchasing windows, clients most often know almost nothing about the profile and other components used for assembly. To simplify the formulation as much as possible, window profiles are the elements from which the framework of frames and sashes is made. Their choice is influenced by many factors that are recommended to be taken into account. Profiles are responsible for the stability of window structures, energy saving, sound insulation, appearance and tightness, and the durability of windows also depends on them.

Customers usually receive information about the characteristics of PVC systems from the manager in a highly compressed form and may make a mistake in their choice. After all, they do not have basic knowledge and time to think through different options. As a result of such actions, buyers do not get what they wanted. To avoid falling into such situations, you need to fundamentally change your approach to the ordering procedure. Our article will tell you how to choose a profile for plastic windows and what else you need to pay close attention to.

What to consider when choosing a PVC profile

To make a successful purchase of windows, you need to correctly build the sequence of actions. First of all, you will need to find out which profile is better before ordering plastic windows. That is, first the brand and type of system are selected, and then the manufacturing company. To find a suitable system, you need to comprehensively consider several criteria.

Profile class

The set of industrial standards RAL-GZ 716/1, which is relevant for EU countries, provides for 3 classes of window profiles - A, B, C. This division and the requirement to mark systems protected buyers from purchasing products that do not meet their requirements. Systems of different classes differ from each other according to 2 main characteristics:
  • composition of raw materials for co-extrusion of profiles;
  • thickness of external and internal walls.


The service life, reliability and aesthetic appearance of windows depend on the quality of raw materials and the thickness of the plastic.
The durability of class A products ranges from 40 to 60 years, and class B is only 20 years. Class C profiles will last only 5 years, but they are not commercially available.

Profile width and number of air chambers

The width (installation depth) and the number of chambers affect both the stability of the windows and their heat-saving properties. The greater these parameters, the warmer and stiffer the structures assembled from such a profile. Today, the market offers systems that have from 3 to 8 cameras and installation depths from 58 to 127 mm.

Thickness of external and external walls

These parameters affect the strength, durability and level of load resistance. For profiles of different classes, these indicators differ as follows:

A-class– the outer walls must exceed 2.8 mm, and the internal jumpers must be at least 2.5 mm;
B-class– the minimum allowed by the standard for external walls is 2.5 mm, and for internal walls – 2 mm.

The thickness of the profile walls also determines the level of noise absorption of window structures and their energy efficiency.

With the same number of chambers and the same installation depth, class A windows are warmer and quieter than class B models.

Reinforcement

Plastic windows without reinforcement can become deformed due to the load from large sashes that are heavy. This process entails depressurization of the structure. To prevent this, special metal inserts are inserted into the internal chambers. They differ from each other in cross-section and wall thickness, which should not be less than 1.2 mm. Their optimal thickness is 1.5 mm.

Today, leading European manufacturers of premium systems are actively replacing metal liners with elements made of durable fiberglass. Without sacrificing strength, they reduce the weight of windows and increase their energy efficiency.

Environmental friendliness of PVC

When producing profiles, various stabilizers and modifiers are added to pure PVC to improve the strength, color and heat resistance of the products. Previously, many manufacturers used additives that contained harmful lead. Although studies conducted in Europe partially dispelled buyers' fears and proved that PVC is harmless to health, fear of this metal remains. In addition, lead is undesirable in plastic recycling. As a result, manufacturers replaced the harmful additive with a new, completely safe stabilizer, CaZn.

The biggest concern is not the certified products, but the profiles made in artisanal conditions. Such products may contain lead and other substances harmful to health. In order not to order windows from such components, you need to require a certificate of compliance with environmental safety requirements.

Maximum glass width

Different profiles have different maximum thicknesses of double-glazed windows that can be installed in windows. Typically, this parameter directly depends on the installation depth of the system. The larger it is, the thicker the double-glazed windows can be used to complete the windows.

With the advent of selective glass, there was no longer a need to use thick double-glazed windows to retain heat. Three-chamber models are recommended for use only in northern regions or in noisy areas (to increase the level of sound absorption of windows).

Number of sealing circuits

Modern profile systems have 2 or 3 sealing circuits. The tightness class of structures depends on their number. If the windows are planned to be used in conditions of high wind loads or when low temperatures, it is advisable to give preference to profiles with 3 sealing contours.

Rebate depth for installation of double-glazed windows

This parameter is rarely paid attention to, although it has important. The depth of the rebate affects the likelihood of condensation occurring around the perimeter of the double-glazed windows. For profiles with a short landing distance, the glass around the spacer quickly cools in winter. This leads to the formation of condensation. To reduce the risk of it falling out, it is recommended to give preference to systems with a rebate depth of at least 20-21 mm.

Lamination

Most window companies additionally provide plastic lamination services. Its essence is to apply a polymer film with a plain or tree-like decor on one or two sides of the profile. If you plan to install colored windows at a facility, it is recommended to find out exactly what coatings the manufacturer offers.
During the search process, you cannot limit yourself to studying profiles. Thermal characteristics windows depend no less on double-glazed windows and fittings.

How to choose a suitable plastic profile if you need warm windows

To figure out which profile to choose for PVC windows with high energy efficiency, you first need to understand how heat is retained indoors. Fittings, double-glazed windows and, of course, the profile system are responsible for this process. Most heat is lost through the translucent filling, so you need to take care of this part of the window structure first. However, without taking into account the characteristics of the profiles, it is impossible to complete this task, since there are 2 ways to increase the energy efficiency of windows:
  1. Install thick double-glazed windows– such integration is only possible in structures assembled from profiles with an installation depth of 70 mm or more. The number of internal cameras in such windows is usually 5-6 pieces.
  2. Install single-chamber double-glazed windows with selective coating– such installation does not require a powerful profile. However, the use of 3-chamber systems with an installation depth of 58-60 mm will lead to heat leakage in the area of ​​the sashes and frame, so a 5-chamber profile would be the best option.


To make warm windows With any type of double-glazed windows, it is necessary to use profiles with increased installation depth for assembly. Otherwise, the energy efficiency of the structures will be insufficient to maintain a comfortable temperature in the interior.

Which profile is better if you need large windows?

Large structures experience high loads. They must withstand the weight of heavy double-glazed windows and gusts of wind. Since not all buyers know when ordering large plastic windows which profile is best to choose, they may subsequently encounter deformation of large-sized structures. To avoid this, you need to follow several recommendations:
  • give preference to a multi-chamber A-class profile with an external wall thickness of 3 mm and an installation depth of 80-86 mm;
  • order closed reinforcement with steel liners with a wall thickness of 1.5 mm;


Based on these two points, you can choose large windows that will last for many years and will not cause any trouble.

Which profile is suitable if you need colored windows?

Laminated, painted and lined with acrylic – these are the types of colored windows. All of the listed plastic window profiles are on sale today, but most buyers do not know how to choose the most suitable one. In order for the designs to fully meet the client’s needs, it is necessary to comprehensively evaluate:
  • service life of decors;
  • operating conditions of coatings;
  • cost of color profiles.


In addition to systems lined with decorative coatings, manufacturers offer body-painted profiles. They retain their aesthetic characteristics throughout the entire service life of the structures.
If windows with dark lamination are planned to be used on the sunny side of the building, you need to find out whether PVC can withstand overheating for a long time. Inexpensive profiles quickly soften under such conditions, which ultimately leads to deformation of the sashes and frames.

What to choose if you need secure windows

To make safe windows, you need a profile with a fitting groove offset that will allow installation. In addition, it is necessary to equip the structures with reliable steel reinforcement. The more cameras a profile with an increased installation width has, the more difficult it is to open such windows from the street side.
Attempts to break into windows high level safety may cause minor damage to profile structures. As a result, for the manufacture of such models it is recommended to choose systems made from environmentally friendly plastic.

How to choose the right profile at a good price

Systems that meet all the most stringent requirements belong to the premium class. But this does not mean that buying high-quality windows excludes savings. With the right approach, you can reduce your costs a little.

Firstly, you will need to first find out, when ordering inexpensive plastic windows, which profile to choose for your climate. Not all regions require maximum thermal insulation values.
Secondly, take into account the location of your window openings. If the windows face the courtyard, then there is no point in overpaying for increased sound insulation characteristics.


If you absolutely require structures that retain heat well, do not allow noise to pass through and make it difficult to break into, use our advice, without sacrificing quality.

Selecting a profile is the first priority from which you should begin the window purchasing procedure. This process requires prior knowledge of the basic information necessary for a successful search.

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 and are in demand because they have a reasonable price, are reliable, functional, durable and very comfortable. 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's artificial, but still good material, 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 short, an ideal 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 clear glass, which transmits light 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 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 you to save the package exact dimensions and the correct form. 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 option seal. It must be strong, durable, elastic, heat-resistant, and not emit unpleasant odors.


Table. Types of seals.

ViewDescription
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.
EPDMRubber 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. For self-replacement It won’t work - it’s all too complicated.
SiliconeThis 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.
RubberA 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 from 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.

TypeDescription
TurningThe usual option, the same as for wooden windows. Plastic frame just opens and closes vertical axis. The fittings can be installed on the left or right side of the frame.
FoldingSuch 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 still an element limiting the angle of rotation.
Tilt&TurnThis 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.
SlidingSuch 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 will be able to 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.

The companies Rehau and Proplex have a good reputation in the modern market of plastic windows in the middle price segment, but what is better - undeniable and respect-inspiring German quality, time-tested, or Russian ergonomics using Austrian technologies - is difficult for the average buyer to understand. Judging by the reviews online, the products of both companies are worthy of attention. A detailed comparison of their designs will help you understand all the intricacies of your choice in order to spend your savings wisely and get the warmest, quietest, strongest, most durable, safe plastic windows possible.

Rehau and Proplex product range

To get a more complete understanding of the strengths and weaknesses of Proplex and Rehau products, it’s worth starting with a brief historical information and get acquainted with their range.

Rehau is a world-famous German concern operating in Germany since 1948, which released the first profile for PVC windows in 1959. Today its range includes more than 10 types, the most popular of which are the following:

  • Premium - a five-chamber premium option with a heat loss resistance coefficient of 0.82 at 70 mm. Can be used with double-glazed windows up to 42 mm, suitable for glazing buildings in harsh climatic conditions, as well as in high-noise areas.

Advantages of Rehau and Proplex

The range of both competitors is impressive. In order to decide: Proplex or Rehau, it is necessary to analyze the advantages that their products have.

Benefits of Rehau


A comparison of Rehau's offerings with analogues of its main competitors made it possible to identify a number of advantages of the German concern:

  1. The very first window from Rehau was installed in Germany more than half a century ago, it is still standing, which allows us to judge the quality and durability of German products.
  2. A wide range of design options allows you to implement any design projects.
  3. The line includes models of different price categories - from economy to premium class.
  4. Their window frames are as warm as possible (up to 1.05 m2°C/W), quiet (up to 47 dB).
  5. Products are continuously improved, there are innovative models, reinforced in bulk using our own technology, are lighter, but at the same time very durable.
  6. A high-quality two- or three-circuit two-lobe seal provides the best sealing of windows.
  7. Excellent appearance - a snow-white, shiny, very smooth surface that does not turn yellow over time, practically does not become dirty, which reduces maintenance requirements to a minimum.
  8. Warranty for 60 years.

Benefits of Proplex


Windows from the Proplex company also have their undeniable advantages:

  1. Manufactured at a Russian plant in compliance with Austrian technologies - affordable quality.
  2. Environmental friendliness of windows, Proplex is the first Russian company that does not use the heavy metal lead as part of its profile. It is replaced with calcium-zinc additives, which makes the products as safe as possible for humans and the environment (confirmed by EcoMaterial Green in 2017).
  3. Scratches are not visible on the smooth semi-matte surface.
  4. The products are low maintenance and easy to clean.
  5. Good value for money.
  6. The versatility of the components, which makes all variants of the profile line compatible with each other.
  7. Adaptability to any Russian climatic conditions.
  8. Sixty-year warranty.

The main differences between Rehau and Proplex

Windows from the Rehau profile differ significantly from Proplex products, which becomes clear even when superficially comparing competitors’ offers:

  1. The range of the German concern is much wider, and over 60 years of active activity it has developed more proprietary and unique manufacturing technologies than the Russian one over 20 years of existence on the market.
  2. The minimum thickness of the window profile for Proplex is 58 mm, it has 2 or 3 chambers, the largest possible width of a double-glazed window is 24-34 mm, heat loss resistance is from 0.405 to 0.70, and for Rehau it is 60 mm, 3 chambers, 0. 64-0.65 m2°C/W.
  3. The maximum performance of products from a Russian manufacturer is a frame of 70 mm, 4 or 5 chambers, a double-glazed window of 42 mm, a resistance of 0.80 - 0.82, a German one - 80-86 mm, 6 chambers, a double-glazed window of 51-54 mm, a resistance of 0.90 - 1 .05.
  4. The Proplex company has a profile in its line with minimal characteristics and cost, designed for secondary glazing, for example, balconies or verandas, that is, in places where aesthetics or cost savings more important than heat and silence.
  5. Rehau has a unique code on each product, which can be used to check originality.

Comparison of Rehau and Proplex profiles by characteristics

The main thing you need to pay attention to when choosing a manufacturer is the technical characteristics and features of its products. To decide between Rehau and Proplex, it is necessary to conduct a detailed comparison of their profiles.

To decide in favor of one of the manufacturers, you should compare their offers according to the following characteristics:

  • wall thickness of window frames;
  • number of cameras;
  • quantity and quality of sealing circuits;
  • type of reinforcement;
  • installation width;
  • thickness of double-glazed windows;
  • appearance;
  • service life.

Waterproofing and quality of sealants used

Good waterproofing is a guarantee that the window will not subsequently fog up, accumulate condensation, “grow” mold, or freeze. Waterproofing of PVC windows is carried out using a special sealant arranged in contours, from the Proplex company, for example, in most designs there are two of them. Rehau also basically has two sealing circuits everywhere, except for the latest new product Geneo, in which there are three of them.

An important role is played by the material (mainly EPDM) of the seal, as well as its shape. Rehau has a two-leaf rubber seal without internal cavities. It does not collect moisture, does not stretch, does not age, and retains all its properties unchanged while in temperature range from -40 to +120 degrees.

Sound and heat insulation

A plastic window, first of all, should be warm, and secondly, it should well insulate the room from street noise. These properties are determined by the structure of the structure - its depth, wall thickness, number, size, location of air chambers, quality, quantity of sealant. If we compare the maximum thermal insulation values ​​of Proplex and Rehau plastic windows by class, the Russian manufacturer in the premium category is noticeably inferior to the German one - 0.81-0.82 versus 0.95-1.05. In other classes, the difference in heat transfer resistance is not too obvious:

  • economy - 0.64-0.65 for Rehau versus 0.64-0.70 for Proplex;
  • the standard is 0.80-0.85 for the Germans versus 0.80 for the Russians.

When it comes to sound insulation, Rehau also holds its own here. In their budget models this figure is 30-35 dB, in more expensive ones – 45-47 dB. Proplex does not specify the sound insulation parameter by type pvc profile, but claims that in any of them it is at least 30 dB.

Reinforcement type

The strength of the window structure is determined by the presence of a reinforcing base inside it, made of steel tape with a thickness of at least 1.2 mm for small windows and at least 1.5 mm for large windows. Important nuance– shape of the reinforcing liner. It can be U, G, G-shaped or square. The most durable is the last one, but the G-shaped base is only slightly inferior to the square one.

Basic models of Proplex window profiles are made with U-shaped reinforcement, and premium options are made with square reinforcement. Rehau has a similar situation - budget variations have P-reinforcement, and more expensive ones have G-reinforcement. It would be possible to count the draw, but thanks to its latest development - the RAU-FIPRO fiber reinforcement technology, embodied in Geneo, the German manufacturer takes the lead. The bottom line is that the reinforcing mesh is placed in the structure itself during its production, so additional reinforcement with a steel liner is no longer required. The strength characteristics remain at the same level, but the weight drops almost by half, which expands the range of applications of such frames and extends the service life of the fittings in them.

Installation depth of PVC profiles

Installation depth is the thickness of the frame in the opening. All properties and technical specifications. Considering the offers of competing manufacturers, the following can be noted:

  • German budget models have a frame of 60 mm, Russian ones – 58 mm;
  • Rehau also has designs in 70, 80, 86 mm with heat retention coefficients of 0.80-0.85, 0.95, 1.05, the deepest Proplex profile is 70 mm, heat saving index is 0.80-0.82 .

It follows that Rehau products are significantly ahead of Proplex products in this parameter.

Thickness of the outer wall of the profile

Outer wall thickness window frame largely determines its strength, durability, wear resistance, as well as resistance to various mechanical damage. World standards and Russian GOST (30673-99) highlight the minimum values ​​of wall thickness on the outside for classes A (the best, at least 3 mm in the world, from 2.8 mm in Russia), B (from 2.5 mm), C (less than 2.5 mm).

At Rehau, all standard and premium types have a wall thickness of 2.8, 2.9, 3 mm, respectively, they belong to the highest class. Walls in budget variations with a thickness of 2.7 mm, which allows them to be classified as class B. The Proplex plant only has PVC profiles Premium belongs to category A, the rest to B or even C.

Number of air chambers

The main technical characteristic of a window profile is the number of chambers, which for Proplex varies from 2 to 5. Rehau has options with 3-6 chambers. Air chambers, more precisely, their number and size, are responsible for ensuring that the rooms are quiet and have a comfortable temperature. The more there are, the higher the energy saving and noise insulation performance.

Proplex windows have leaders among offers ( Hit, Premium) have five chambers, and the heat saving index is 0.81-0.82. Rehau is doing much better. Their five-chamber Delight, Brillant, Grazio heat loss resistance is 0.80, 0.81, 0.85, and for six-chamber Intelio,Geneo– 0.95, 1.05. The difference is obvious.

Maximum glass thickness

The thicker the glass unit used in the window, the quieter and warmer the room will be. Thick double-glazed windows can only be installed in a deep frame.

The German concern has proposals:

  • 60 mm for glass units up to 32 mm ( Blitz, Euro);
  • 70 – 41 mm ( Delight, Brillant, Grazio);
  • 80 – 51 mm ( Intelio);
  • 86 – 54 mm ( Geneo).

Proplex's profile is significantly behind in this regard, having:

  • 58 mm and allows you to install double-glazed windows 24–34 mm ( OUTLINE, Basis, Optima);
  • 70 – 42 mm ( Comfort, Premium, Hit).

Appearance and service life

Competitors' windows also differ in appearance. Rehau designs are as smooth, shiny, and glossy as possible with a bright white surface that does not turn yellow, gray, or fade over time. At the same time, dirt practically does not linger on it, which allows you to replace a thorough washing of the frame with wiping it with a damp cloth only a couple of times a year.

The profile for plastic windows from Proplex does not have a bright white color, it is rather milky with a semi-matte, non-shiny surface. It looks stylish, but somewhat dull. But scratches are practically invisible on it. It retains dirt, but washes off quite easily.

As for the service life, both companies guarantee that the profile will retain all its quality characteristics for 60 years.

Comparative table of Rehau and Proplex profiles

To summarize the comparison, it is worth once again turning to the main characteristics of the Proplex and Rehau profiles, collected for convenience in one table.

Comparing the profiles of competitors, it can be noted that the 58 mm Proplex designs technical specifications similar to 60 mm Rehau products. They are just as warm and quiet, but they are inferior to the Germans in strength, since the thickness of their outer walls does not even reach class B.

The 70 mm Russian profile for PVC windows is positioned by the manufacturer as a premium product, while the Germans only belong to the standard class, while in terms of heat saving, albeit just a little, Proplex loses (0.80-0.82 versus 0 .80-0.85). Premium offers from Rehau have a thickness of 80, 86 mm, as well as maximum heat retention and sound insulation (0.95-1.05, 47 dB).

Price comparison between Rehau and Proplex

An important factor is the cost of the products. Both manufacturers classify their products in the middle price category. To complete the information, all that remains is to compare the estimated prices for the same windows, for example, double-leaf windows from Proplex and Rehau.
