Which plastic profile to choose. Which profile of plastic windows is better. How to extend the life of seals

What is a quality profile?

The key to the quality and durability of a metal-plastic window is a high-quality PVC profile. Even if at first glance they are all the same, in reality this is far from the case ..

The entire profile from which the windows are made is certified.

The ISO 9001:2000 quality management system certificate is issued to industries that have a well-organized management system in compliance with all technological, economic and organizational requirements typical for the production of developed countries. Both Russian VEKA plants have this certificate.

Wider, stronger, warmer

Profile width is one of its main characteristics. Many window manufacturers promise a couple of extra millimeters to the profile width in their advertising campaigns, but are they really useful?

The following offers are most often found on the market:

classic profile 58 mm;
profile 70 mm with increased installation width;
profile VEKA SOFTLINE 82

The width of 58 mm is due to the "classics of the genre" - wooden frames, which were replaced by plastic windows. The EUROLINE 58 mm profile allows the production of modern warm windows that meet the requirements of most customers in different climatic zones. Subject to proper manufacture and installation, this best profile for windows in any room.

A profile with a width of 70 mm is a proposal that appeared in the 80s of the last century. Having higher heat-saving soundproofing characteristics, this profile is especially fond of Russian consumers. In the product group of VEKA profiles, SOFTLINE, SWINGLINE and PROLINE have a width of 70 mm.

Now another novelty has appeared on the market - the SOFTLINE 82 profile. Innovative multi-chamber system, elegant style and a choice of more than 40 modifications guarantee the satisfaction of the most demanding customer. The SOFTLINE 82 system provides the best insulating performance, is fully compatible with 70 mm profiles and can be installed in any home.

The choice of profile width for the window largely depends on the installation location (window in the office, tambour door, Entrance door to the store, windows to country house) and climate.

Chamber… Ensemble

The second characteristic of the window is the number of cameras in the profile. There are three in the standard. The first one is for condensate drainage, the second one is for placing a reinforcing metal insert, and the third one is for fixing parts of the fittings and creating an additional air gap for better window tightness. The number of chambers depends on the width of the profile. So, a 58 mm profile can have a maximum of three cameras, but a 70 mm profile - preferably four. For a 90 mm profile, six chambers are the norm.

Increasing the number of cameras with the same profile width does not significantly change the characteristics of the window. To improve the heat-saving characteristics, more wide profile, and not more partitions in it.

Full package

Another important point- double glazing. The number of glasses in a window affects its characteristics and cost. The most common are double glazing, but you can order windows with single glazing or triple glazing.

Three-chamber windows are warmer, but they weigh more and require high-quality installation and stable construction. Single glazing is the coldest. It can be used for glazing unheated balconies, as well as summer houses. Double glazing is optimal in terms of technical characteristics, and allows you to maintain comfort indoors all year round.

real class

There are two classes of metal-plastic profiles. First, class A with a thickened outer wall as the best profile for windows, doors and frame glazing.

The second, class B, is a lightweight profile with a thinner outer wall, the so-called "object" profile. It has a slightly lower cost, but does not guarantee the preservation of the characteristics of the window throughout its operation. Windows from the "object" profile, as an economical option, can be offered by absolutely all manufacturers, but you should remember that such a window may have weaker corner joints, poorer dimensional stability, lower energy-saving characteristics, risk of premature wear of fittings, shorter service life.

Important Conclusion

Summing up the reasoning on the topic of choosing a profile for a metal-plastic window, we emphasize:

The presence of certificates confirms the quality.

According to the mounting width, all profiles are divided into two main classes: 58, 64 mm and 70-76 mm. Within the class, the thermal characteristics are the same. A profile with a width of 68 mm and a profile with a width of 72 mm do not differ from each other.

The number of cameras affects the window quality only if the profile belongs to different width classes.

The most common is double glazing.

Class A profile is the leader in reliability and quality.

When choosing a profile for plastic windows, be able to hear the necessary information and filter out advertising. The quality of your windows depends on your choice. Take the time to make the right choice!

Plastic windows have long ceased to be a luxury item and have become a convenient and affordable option to replace traditional wooden frames. And naturally, every person wants to put himself in the house with the best plastic windows. However, the market offer of PVC window profiles is very large, and choose suitable option sometimes it is quite difficult. Expensive and cheap, imported and domestic, three-chamber and five-chamber ... What should the buyer do? Carefully delve into the technical details of the production of window profiles? Not at all. It is enough to have some idea of how the profiles of plastic windows differ from each other.

Definition

Profile- the basis of the future window, we can say that this is its skeleton. The durability of the structure depends on it. And when the question arises, what is the difference between PVC windows, then most often it is the profile that is meant. The main difference between window profiles is the number of cameras and their design. According to GOST 30673-99, chambers in PVC windows must be at least two. Usually produce three-chamber profiles.

Window profile chambers are air cushions located along the perimeter of the frame and provide a high degree of heat and sound insulation. What are the fundamental differences between three-chamber and five-chamber profiles?

Comparison

The five-chamber profile is much thicker, therefore, when installing such plastic windows, the likelihood of condensation and freezing of the structure is significantly reduced. In terms of rigidity, five-chamber plastic profiles are also superior to three-chamber ones. The greater the rigidity of the profile, the less likely it is that the geometry of the structure will change, as a result of which the window will let in cold, heat, and dust. Naturally, a five-chamber profile is more expensive than a three-chamber one.

3 and 5 chamber profiles

Also, the profiles of plastic windows may differ in the quality of the polyvinyl chloride used in their production. It is difficult to determine the quality of plastic when buying, all its shortcomings will come to light only during operation. Poor-quality plastic quickly wears out - scratches appear on it, the shine disappears and the product loses its attractiveness. To prevent this from happening, you should buy profiles made by companies with a good reputation.

To increase the strength and reliability, as well as for resistance to external influences, the profiles of plastic windows are reinforced. To do this, a metal profile made of galvanized steel or aluminum is laid inside the profile frame. Another important difference between plastic window profiles is their design and surface coloring. As a rule, these properties are determined by the method of the production process.

When buying windows, customers most often know almost nothing about the profile and other components that are used for assembly. If we simplify the wording as much as possible, then window profiles are the elements from which the frame 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 the wrong choice. After all, they do not have the basic knowledge and time to think. different options. As a result of such actions, buyers do not get what they wanted at all. In order not to fall into such situations, it is necessary to fundamentally change the 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 a sequence of actions. First of all, you will need to find out which profile is better before the moment when plastic windows are ordered. That is, first the brand and type of the system are selected, and then the manufacturer. To find a suitable system, several criteria must be considered comprehensively.

Profile class

The set of industrial standards RAL-GZ 716/1, which is relevant for the EU countries, provides for 3 classes of window profiles - A, B, C. Such a separation and the requirement to mark the systems without fail protected buyers from purchasing products that do not meet their requirements. The systems of different classes differ from each other in 2 main features:

composition of raw materials for profile co-extrusion;
thickness of outer and inner walls.

The service life, reliability and aesthetic appearance of windows depend on the quality of the raw materials and the thickness of the plastic.

The durability of class A products is from 40 to 60 years, and B - only 20 years. Class C profiles will last only 5 years, but they are not found on the open market.

Profile width and number of air chambers

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

Thickness of outer and outer walls

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

A-class- the outer walls must exceed 2.8 mm, and the internal lintels 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 level of noise absorption of window structures and their energy efficiency also depend on the thickness of the profile walls.

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 be deformed due to the load from large sashes that have big weight. 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.

Environmentally friendly PVC

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

The biggest concerns are not certified products, but profiles made in artisanal conditions. These products may contain lead and other harmful substances. In order not to order windows from such components, you need to require a certificate for compliance with environmental safety requirements.

Maximum glass width

Different profiles differ in the maximum thickness of the glass units that can be installed in windows. Usually this parameter directly depends on the installation depth of the system. The larger it is, the thicker double-glazed windows can be used to complete windows.

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

Number of tightness circuits

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

Rebate depth for double-glazed windows

This parameter is rarely paid attention, although it is important. The depth of the rebate affects the likelihood of condensation around the perimeter of the double-glazed windows. For profiles with a small landing distance, the glass around the distance frame cools quickly in winter. This leads to the formation of condensate. 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 lies in the application of a polymer film with a plain or tree-like decor on one or two sides of the profile. If the installation of colored windows is planned at the facility, it is recommended to find out what kind of coatings the manufacturer offers.

The search process should not be limited to the study of profiles. The thermal performance of windows is no less dependent 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 inside the premises. Fittings, double-glazed windows and, of course, the profile system are responsible for this process. Most of the heat is lost through the translucent filling, so you need to take care of this part first. window construction. However, without taking into account the characteristics of the profiles, this task is unrealistic, since there are 2 ways to improve the energy efficiency of windows:

Install thick double glazing– such integration is possible only 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.
Install single-chamber double-glazed windows with selective coating- for such installation a powerful profile is not required. However, the use of 3-chamber systems with an installation depth of 58-60 mm will lead to heat leakage in the sash and frame area, therefore the best option there will be a 5-chamber profile.

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

Which profile is better if you need large windows

Large structures are subject to high loads. They must withstand a lot of heavy double-glazed windows and gusts of wind. Since not all buyers know when ordering large plastic windows which profile is better to choose, they may subsequently encounter deformation of large-sized structures. To avoid this, you need to follow a few recommendations:

give preference to a multi-chamber A-class profile with an outer wall thickness of 3 mm and an installation depth of 80-86 mm;
order closed reinforcement with steel inserts 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 trouble.

Which profile is suitable if you need colored windows

Laminated, painted and lined with acrylic - these are colored windows. All the listed profiles of plastic windows 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 needs of the client, it is necessary to comprehensively evaluate:

service life of decors;
operating conditions of coatings;
the cost of color profiles.

In addition to systems lined decorative coatings, manufacturers offer mass-dyed profiles. They retain their aesthetic characteristics during the entire service life of structures.

If windows with dark lamination are planned to be used on the sunny side of the building, it is necessary to find out if PVC can withstand overheating for a long time. Inexpensive profiles in such conditions quickly soften, which ultimately leads to deformation of the sashes and frames.

What to choose if you need safe windows

For the manufacture of safe windows, you need a profile with such an offset of the fitting groove that will allow you to install. 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 side of the street.

Window hacking attempts high level security can cause minor damage to profile structures. As a result, for the manufacture of such models, it is recommended to choose systems made of environmentally friendly plastic.

How to choose the right profile at a bargain price

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

First, you will need to find out first, when ordering inexpensive plastic windows, which profile to choose for your climate. Not all regions require maximum thermal insulation performance.
Secondly, consider the location of your window openings. If the windows overlook the courtyard, then it makes no sense to overpay for increased sound insulation characteristics.

If you unconditionally require structures that retain heat well, do not let in noise and make it difficult to hack, use our advice without sacrificing quality.

Choosing a profile is the first step from which you should start the process of buying windows. This process requires prior familiarization with the basic information necessary for a successful search. You can find all the latest information about components for assembling window and door blocks on the OknaTrade website in the "Useful Articles" section.

Profile PVC Profile wooden profile PVC windows Wooden windows

In choosing a profile for a double-glazed window, every little thing is important. It would seem that all plastic windows are the same. However, in reality, it turns out that the service life of approximately identical products is different, and the quality characteristics of some often leave much to be desired. Therefore, it is necessary to approach the choice of a profile with all responsibility.

Structure

The PVC profile represents a plastic frame for a double-glazed window. Despite the apparent simplicity, this design is not simple. In the cross section of the profile, many air chambers are visible. At their expense, the safety of heat is ensured. The more of them, the better the level of thermal protection.

For rigidity and reliability, a metal frame is inserted into the base of the profile. This manufacturing process is called reinforcement. Due to the reinforcement, the profile becomes stronger, the possibility of its deformation and resistance to changes in the structure under the influence of negative factors is excluded environment(e.g. rain, gusty winds and frost). Profile material is polyvinylchloride.

Regardless of the type of profile, the metal strips inside it are an important factor which you need to pay attention to when ordering. It is because of them that the profile is called metal-plastic

Longitudinal chambers in frame structures are responsible not only for the preservation of heat. They are frame reinforcements. The outer sections drain condensate that may occur inside the cavities due to the difference in temperature between indoors and outdoors.

At the bottom of the structure, they have a connection to the atmosphere. Due to this, drops flow down to the street when they appear. The presence of such holes does not affect the level of heat in the room in any way: the heat in the room does not decrease. Outwardly, such elements do not spoil the aesthetic appearance of windows, since in most cases they are closed with plugs or are simply not visible against the background of the entire structure. The presence of these holes indicates quality window. It will be more durable compared to modification without them.

Peculiarities

Plastic profile (PVC) is the basis of windows. The reliability and durability of the entire structure depends on it. Sash and fittings are made from this material, a double-glazed window is installed in it. The main characteristics of the window structure depend on it, including the level of sound insulation, as well as tightness. It also affects the preservation of heat in the room.

The metal-plastic profile is a sash and a frame with a different number of chambers (up to 8). The most popular products among buyers are options for 2-3 compartments. The fundamental factor of technical characteristics is the size of the windows. So, varieties of panoramic type are characterized by lower noise and heat insulation properties in comparison with their smaller counterparts.

Due to the increase in heat retention in such structures, during installation, it is necessary to resort to mounting foam when filling chambers. In addition, structures can have a fiberglass coating with stiffeners. One of the significant characteristics during installation is the thickness of the ceiling and the installation width. They are responsible for the rigidity of the profile structure and the reliability of the valves themselves.

A modern plastic profile for windows differs from analogues in the period of its appearance. Today, its quality characteristics are quite high, as well as decorative possibilities. Technological and functional frames have long supplanted analogues made of wood, making glazing reliable and ergonomic. Unlike wood, PVC does not shrink. Such windows will not be deformed during operation.

PVC windows can be installed in buildings different type. They can replace wooden frames in houses whose active phase of shrinkage has already been completed. At the same time, residents will be protected not only from cold and noise, but also from dust. Usually such designs pull out any, even boring design premises and harmoniously look in the architectural context of buildings of various types. The ability of plastic to imitate any texture makes it possible to use such frames in any design style.

The surface of the profile can be matte, glossy and even three-dimensional. The color schemes of such products today are diverse and can satisfy any taste. For example, you can choose a profile for expensive types of wood (wenge), show an imitation of aged wood.

When more luxurious solutions are needed, stone-like plastic and even reptile skin are chosen. The drawing depends on the preferences of the client: brands today are often ready to fulfill an individual order of the buyer.

Characteristics

Among the main characteristics of such a profile can be noted:

resistance to oxidation, high temperature;
resistance to moisture and water;
safety for the health of households;
aesthetic appeal;
low coefficient of thermal conductivity;
variability of forms of structures;
fitting into any historical design of architecture;
varying degrees of complexity of designs and mechanisms of windows;
rich color palette.

In care, such a profile is simpler than a wood counterpart. It does not need to be covered with stain or other paint over time. To clean the surface, in most cases it is enough to use a damp cloth or a semi-dry sponge. However, in case of significant mechanical damage, scratches may form on it, which cannot be hidden in any way. This is the main disadvantage of such structures.

Options with a different number of cameras differ in performance. For this reason, their choice is often based on the climatic conditions of the region. If the winters there are cold and windy, the cameras try to choose from big amount compartments. In this case, preference is given to the greater thickness of the double-glazed window.

The profile itself is environmentally friendly. He is far from harmful plastic, which was produced in production earlier. Such a frame with sashes will not emit toxic substances during the operation of the window. When choosing, it is important to pay attention to the number of cameras. If the glazing is cold, there should be at least 3 of them. Such profiles can be used for balconies, loggias and rooms technical type. When it is planned to glaze heated buildings (school, house, apartment, restaurant), the number of required cameras increases to 5.

Kinds

In addition to polyvinyl chloride, aluminum or steel is used in the construction of PVC profiles for windows. Metal is used in horizontal and vertical elements . The production of profiles is subject to the requirements of GOST 30673-99 in our country and EN 12608 SR in European countries.

The profile of the first group is the best option and is intended for residential buildings. It is characterized by a thickness of the outer walls of the order of 2.8 mm or more, internal - from 2.5 mm. This variety is more resistant to accidental mechanical damage. The analog of category "B" is distinguished by a smaller wall thickness.

The inner walls have a thickness of 2 mm, while the outer ones are thinner by 1/3 mm. It seems to be a little, but that is why such options are less resistant to mechanical stress. They can be used for heated and unheated rooms. The profile marked "C" is characterized by smaller thicknesses of both walls. In the language of specialists, it is called object.

Unlike the two previous options, it does not have a normalized thickness (it is clearly less than the categories "A" and "B"). The disadvantage is the design of this type itself: it does not have opening doors. The solidity of such windows makes them less in demand among buyers. These varieties are used in unheated rooms.

In fact, all existing types of plastic profile for windows can be divided into 3 types:

economy;
standard;
lux.

Window plastic profile is the main and additional. On the shelves of stores today you can buy a profile:

connective;
pedestal;
reinforcing;
expansion;
P- and F-shaped.

These are tubular structures with blocks inside, which form the frame of the window. Chambers vary in shape and volume. Some of them are not connected either with each other or with the external environment. They are hermetic, while others serve for ventilation. Depending on the size, air filling and number of chambers, such profiles have different purpose. Some of them are used for technical premises, others can be used for residential buildings.

The L-shaped view is characterized by the strengthening of two profile walls. U-shaped type is a reinforcement of three walls. When closed, all parts are reinforced. In this case, the choice of profile depends, among other things, on the number of glasses in the structure. Cameras in frames directly depend on this.

Varieties differ in the degree of frost resistance. So, frost-resistant versions marked "M" are designed for temperatures up to -50 degrees C (control load). Analogs of normal execution are suitable for regions with sub-zero temperatures up to -20-40 degrees C. The difference depends on the type of base material used.

Dimensions

Profile parameters are determined by its width and thickness. In this regard, manufacturers are trying to adhere to standard values. A common frame version may have dimensions of 58x63x43 mm. In this case, the dimensions of the sash are 58x77x57 mm, the impost - 58x87x47 mm.

When the profile contains 6 chambers, its thickness can be 85-90 mm. At 70mm it usually has up to 5 chambers. In the first case, the profile is thick and not suitable for every window opening. 70mm is considered the best option if up to 5 cameras are needed.

The thickness of the front wall of class "A" is on average 3 mm. For analogues of category "B", this indicator is reduced by half a millimeter. Not the front side of classes "A" and "B" is thinner by 0.5 mm each from the values of the front wall. In category "C" manufacturers do not indicate data. The mounting width of the profile in some varieties can be 104, 110 and 130 mm.

How to choose?

In the modern market for such materials, PVC profiles are presented in a wide range. It's easy for a buyer to get confused. However, do right choice it is quite possible without being a specialist in the field of construction and installation. To begin with, it is worth paying attention to the material itself. Appearance plastic can tell a lot about its quality.

When there is no decorative laminated film on the profile (imitation of the desired texture), one careful look is enough. quality material characterized by a monolithic structure. It should not have roughness, heterogeneity. Any stains, uneven staining are excluded. Noticeable graininess will indicate a fake product.

You can not buy such a PVC profile. Typically, such samples can be found in one-day firms. Such companies offer the installation of windows from their material. It is produced from cheap and harmful raw materials. Therefore, expect from such a profile any quality characteristics it is forbidden.

Yes, and you need to know about the manufacturer before buying components. To do this, you can find out more about the reputation of the company based on reviews.

It is important to understand that profiles have some differences among themselves. They are cut on special machines for certain sizes of structures. This applies not only to the sashes, but also to the uprights and crossbars. Therefore, when buying, you need to purchase the entire set from one brand. Otherwise, you can not count on the perfect joining of the elements, whether it is a connection by special welding or mechanical hardware.

cameras

Before buying, it is important to ask about the number of cameras. Usually high-quality products of eminent trademarks there are more than 5. This is enough, while 7 cavities will be too much. In this case, we must not forget that not the number of chambers, but the wall thickness is more important. After all, they will be responsible for the level of heat to a greater extent.

In addition to options with air chambers, today on the market you can find a PVC profile in which the voids are filled not with air, but with a heat insulator. This is mainly a foam-based material (polystyrene foam) or fiberglass. Such a profile appeared on the market relatively recently.

However, experts believe that it is more effective in terms of heat retention. The disadvantage is the cost of modification, which is noticeably higher than traditional options.

Width

Since the choice of profile involves a comprehensive analysis, it is worth paying attention to the width of the PVC profile. It is often called mounting depth in the language of specialists. In a standard profile, its indicator usually varies in the range of 50-80 mm. The number of cameras inside the element depends on it. Usually, with a smaller width, the design has no more than 3 cavities. When the width exceeds 70 mm, their number increases from 4 to 5.

However, it cannot be assumed that the wider the profile, the more cameras it has. This is far from always true, because, depending on the design features, the profile can be wide (for example, up to 9 cm), but with a minimum number of cavities. Such options may differ in excellent heat-insulating characteristics, since the air supply and the dimensions of the cavities themselves are important in this case.

In some cases, the installation depth can be 10 cm. Such options block the window opening, so they often do not need to install external slopes. Their distinctive feature is the shape of a section in the form of a trapezoid. These windows are called "Dutch", "Danish". They are certainly better than their usual counterparts, although not everyone can afford their installation.

seat

It is impossible to buy a plastic profile without knowing the depth of the insulating glass unit. It is this factor that is responsible for the type of double-glazed window, its quality, as well as heat-shielding properties. A good profile frame is a structure where the glass sheet is at least 1.5 cm away from the frontal cut, overlapping with the profile seam.

If you plan to mount the frame to a depth of 5-7 cm, the seat for installing glass should be 1.8 cm. Few people pay attention to this aspect when buying a profile. However, if you ignore it and rely solely on the width of the profile and the number of cavities in it, you may not be surprised in the future that the double-glazed window fogs up or freezes.

In addition, it is worth paying attention to 4 factors:

Linear expansion. It should be minimal so that no voids form during installation. The higher it is, the smaller the size of the window frame.
elasticity coefficient. The presence of steel is a mandatory criterion for choosing a profile. In this case, the thickness of the inner walls (stiffening ribs) is important.
Resistance to temperature difference and UV rays. Polyvinyl chloride should contain stabilizers to maintain inertness to loss of color and structure.
Sealant. From thermoplastic, thermopolymer, silicone and rubber, silicone products should be preferred. It is resistant to abrasion, inert to temperature changes.

Each profile is supplied with a certificate. It indicates the type of product and the place of its production.

Decor

White frames are considered old-fashioned today. It is replaced by profiles with a laminated film that can imitate any texture. These can be neutral options (gray, black), as well as wood tones. Of course, such a solution for a window structure will cost more, but by paying 15-20% more, the buyer can equip his home, taking into account the choice of a specific design.

If the choice is made in favor of a colored frame, the shade is selected taking into account the interior and exterior. The frame should look beautiful outside and inside. You can build on the color of existing furniture, doors. A color profile may have a related tint, but a different color temperature is undesirable. However, the choice of color profile has its own nuances.

Bright hues won't warm up in the sun like, say, dark rocky or woody browns. This means that when choosing a colored profile, the presence of metal in the frame is mandatory, regardless of the size and shape of the frame. In addition to lamination, manufacturers paint the PVC profile with acrylic coating, supplement it with metal or wood overlays. The very form of the elements is also a decorative technique, which today is more streamlined and can have a complex relief.

To date, you can order a plastic window profile for oak, alder, fir, mahogany, malachite, marble. For more creative design in the palette of shades there are yellow, turquoise, blue and wine shades. Due to lamination, you can decorate the frames with a film with an aging effect. If desired, you can also choose coatings with a three-dimensional effect, creating a sense of volume and relief.

Manufacturers and reviews

Today, many companies are ready to offer the buyer a PVC profile for windows. Highly rated professional craftsmen included several companies:

Presented today 8 different types with different installation depth range (58-90 mm). The number of air chambers inside the profile is from 3 to 6. Equipped with a durable metal frame looks stylish, beautiful and modern.

KBE

This profile is distinguished by the best indicators of quality and technical specifications compared to other brands. The products have a durable White color which does not fade in the sun and for a long time. The profile is represented by three options: "Etalon", "Expert", "Expert+".

These are products of "A" class with a service life of about 40 years. There can be 3 or 5 chambers in the frame and sashes, 3-4 in the impost. Such products can be installed in rooms with a critical temperature of the region (up to -60).

Depending on the model, the profile may have additional horizontal lintels, which ensures reliable fastening of rivers and loops.

Proplex

The domestic manufacturer brings to the attention of buyers a profile created using Austrian technology. The Podolsky plant produces varieties with three and five air chambers with a system width of 5.8 and 7 cm. The width of the double-glazed window, depending on the profile model, can be 4-34 and 12-42 mm. The approximate service life of the product is about 60 years. Profile resistance during heat transfer is 0.78 and 0.81 m2S/W. Designs differ in whiteness and toughness.

Listed in the ranking the best manufacturers whose products have been tested by installers. In addition to the main companies, the products of the Mont Blanc, Trocal and Salamander brands can be distinguished. Good products can be purchased from Aluplast, Funke, Artek. If there is no profile of brands from the rating in the assortment, you can pay attention to these options.

If the choice seems to be a difficult task, you can consult with the seller, noting the necessary questions in advance. For example, if the buyer lives in the southern region, there is no need to order a six- and seven-chamber profile. In this case, an analog for 3 cameras will suffice.

For effective protection from the cold, a resident of a high-rise building cannot install a product with more than 4 cameras. In your house, a five-chamber design is enough. However, it is worth starting from the reliability of the foundation, since the weight of the double-glazed window will be noticeable.

So that the window does not deform over time, before buying it is worth clarifying the presence of a profile to strengthen the frame. In its absence, the window will close poorly over time. In addition, its tightness will also suffer. In addition, you need to understand that a cheap profile is not of high quality. In an attempt to save money, you can lose on quality. And this will be reflected in the reduction of the life of the window.

When buying a profile, you need to pay attention to how the frame is sealed. To avoid the accumulation of condensate, there should be 2 seals at the bottom of the frame. If at least 1 of them is missing, mold will appear on the profile over time. At the same time, the material of the seal itself is also important, which is reflected in its quality characteristics.

For installation, varieties with a width of 58 mm are more often bought. This option is relevant for apartments in high-rise buildings and is present in every line of brands. Larger width options are considered premium products. They are more durable, reliable and differ in terms of noise and thermal insulation compared to the first analogues. However, it is far from always possible to install such structures in high-rise buildings in terms of their load on load-bearing floors.

Finally, it is worth mentioning at least important nuance A: Manufacturer and installer may be different companies. So that in the future they do not throw off the responsibility for a poor-quality window on each other, it is important to initially choose the material correctly. You need to go through each paragraph of the article and note what is appropriate in a particular case. In addition, you will also have to study the installer rating so that the profile is installed as expected.

In order not to run into a fake of a popular brand, you should go to the manufacturer's website and ask for the address of a particular store. Information about official suppliers will allow you to understand whether the store in your city really sells a branded profile. If the site administration gives an affirmative answer, you can buy products. When buying a color version of the profile, it is important to look at each element for different shades: the window should look monolithic.

"Which window profiles are the best?" – a question that is asked by everyone who wants to finally install energy-saving windows in their home. However, despite the external similarity of all structures, inside all the profiles are completely different, some of which do not at all comply with the SNiP of the Russian Federation and are not recommended for installation in residential premises. First of all, when choosing a window system, it is necessary to pay attention to the number of chambers and the coefficient of heat resistance (the higher the better). The next important parameter of PVC windows is the provided opportunity for reinforcement - this increases the load-bearing characteristics of the structure, increases the service life of the system and its resistance to plastic deformation. To make it easier for the buyer to decide on the choice of a high-quality window system, this rating was collected. So, TOP 10 the best firms and models of PVC window profiles:

aluPlast

Aluplast opens the quality rating of window profiles. The company provides a good range of technical solutions for window systems. The latest developments that increase the energy efficiency of structures are embodied in the AluPlast energeto series. The Energeto 8000 model has excellent thermal resistance when installed with triple glazing - 1.27 m2 * C / W. According to the manufacturer, if the structure is not reinforced with steel (this reduces the bearing capacity), its thermal conductivity is significantly reduced, reaching a heat resistance coefficient of up to 1.67 m2 * C / W.

Deceuninck

Deceuninck is ranked 9th in the pvc profile rating. The Belgian company has been manufacturing PVC window blanks for about 40 years at production facilities located in Europe, Asia and North America. The flagship of all Deceuninck lines is the 84mm Eforte model. This system is recommended for installation even in the northern latitudes of Russia due to the high coefficient of thermal resistance - 1.1 m2 * C / W. The service life of "Eforte" is 30-40 years, subject to the temperature amplitude from -60 to +75 degrees Celsius.

Proplex

The Russian company Proplex takes the 8th place in the rating of window profiles in 2018. All Proplex products are produced in Russia, so the prices for finished products from this profile are much lower than imported analogues. Proplex produces 5 different window systems: 2,3,4,5-chamber. For installation in dachas, loggias and non-residential premises, a two-chamber Proplex Outline is recommended - the cheapest design with a heat resistance coefficient of only 55 m2 * C / W. More reliable system recommended for installation in apartments and residential premises is a four-chamber Proplex Comfort with a thermal resistance of 0.8 m2 * C / B, which fully meets the requirements of the RF SNiP.

Kaleva

The seventh place in the ranking of pvc window profiles is occupied by the Kaleva brand. The company produces a dozen various models each of which has its own advantages and disadvantages. The most inexpensive option with everything you need is Kaleva Standart - this is a four-chamber profile with the possibility of steel reinforcement and a built-in double-glazed window filled with an inert argon gas, which has a very low thermal conductivity. The Kaleva Titan Plus five-chamber window system is the company's most heat-saving and noise-suppressing design. Feature of Titan Plus: in addition to the main two-chamber 40mm insulating glass filled with argon, blinds and one more external glass are built into the system - thus, this model provides an incomparable degree of insulation with other analogues, thanks to an insulating glass with three independent air baffles, two of which are filled with argon.

Montblanc

Montblanc (pronounced MONT-BLANC) occupies a leading position in the ranking of plastic window profiles in 2018 in terms of price-quality ratio. Mont Blanc is an Austrian company that has been producing low-cost, high-quality profiles for translucent structures for more than 15 years. Due to the opening of the Mont Blanc industrial plant in the Moscow region in 2001, the company gained wide popularity in Russia. The company produces several lines of window systems: Montblanc, Reachmont, Goodwin and ECP. All products have a 40 to 60 year guaranteed service life and build widths of 58 to 70mm, except for the 80mm Montblanc Grand with six airboxes. A four-chamber Montblanc Quadro system with a thermal resistance coefficient of 0.8 C / W per m2 is recommended for installation - this is a high indicator that meets the requirements of GOST and building codes and rules in many regions of the Russian Federation.

Salamander

The TOP 5 rating of profiles for plastic windows in 2018 is opened by one of the most expensive brands in the rating. The company has three various systems: Salamnder 2d/Streamline/BlueEvolution. The most budget option is considered to be a three-chamber 2D with the possibility of reinforcing the internal chambers with steel. The wall thickness of the Salamander 2D: external 3mm, seam 2.5m, and internal 1mm - this provides a good noise reduction rate (up to 46dB) and high energy efficiency class A +. This model is designed for installation of a single double-glazed window. Salamander BlueEvolution is the next model recommended for installation in any region of Russia. BlueEvolution is the only profile available on the Russian market (meaning at a reasonable price) with maximum width built-in double-glazed window - 60mm (if desired, you can install a three-chamber double-glazed window). Salander BlueEvolution is ideal for the continental climate of Russia: it protects from heavy rains, effectively maintains the temperature even at -40 degrees, and reliably resists drafts, thanks to an elastic rubber seal.

KBE

4th place in the rating of pvc window profiles belongs to the German manufacturer KBE. The name of the rulers at KBE is tritely simple and depends on the width of the profile: KBE 58/70/76/88. As anyone who plans to change windows should know, the wider the system, the more cameras it has, which means that the heat saving indicators of such a design are obviously high.

The best option for installation is the KBE76MD model, a six-chamber design made using lead-free greenline technology from recycled PVC. Recycling PVC allows you to "kill" "two birds with one stone" at once: to recycle PVC waste and save on the cost of raw materials, which directly affects the retail price of the product.

The most important thing in greenline technology from KBE is the complete preservation of the physical and mechanical properties of the material, that is, raw materials of primary processing are no different from recycled materials. The best product from KBE is the 88mm greenline KBE AD: this model has an outer wall thickness of 3mm and 6 independent air compartments inside with the possibility of aluminum reinforcement - all this provides an unconditionally high rate of thermal efficiency and noise reduction.

VEKA

The bronze medalist in the ranking of the best pvc window profiles goes to VEKA. VEKA offers 8 class A models with thickness outer wall 3mm. The most economical solution is VEKO Euroline: a structure with three air chambers designed for an insulating glass unit up to 24 mm (usually two glasses - one chamber), the doors and frames in which it is possible to reinforce for greater reliability of the system.

The energy-efficient A++ class VEKO Swingline series will be the best solution in terms of price and quality for offices and apartments: 5 independent air chambers with an outer wall thickness of 3mm will provide warmth and comfort in the room even on harsh winter evenings. The most expensive and massive copy is VEKO Alphaline. This model is equipped with six air compartments with a total width of 90mm - these are the most heat-saving windows from VEKO in which you can install a double-glazed window up to 50mm thick (3 glasses) and enjoy silence and comfort all year round.

WDS

WDS takes the second place among the best profiles for plastic windows in 2018. The manufacturer has several product lines in its assortment, each of which has a difference in noise reduction coefficient, heat saving and the number of cameras: WDS 400/500, WDS 4/7/8 Series. The best in terms of price-quality ratio is the class A 60mm WDS4 model, equipped with 4 independent air chambers, the possibility of aluminum reinforcement up to 1.5mm. For northern latitudes, it recommends WDS8 series for installation: a six-chamber metal-plastic profile with the possibility of mounting a double-glazed window up to 44 wide - this model retains heat 2.5 times more efficiently than WDS400 / 4Series.

rehau

Rehau is the leader of the rating, the best profile for plastic windows in 2018. The range of the company consists of 7 types of profiles with different number of air chambers, construction width and sound insulation level. The Rehau Euro-design series is an affordable and high-quality three-chamber profile with a thickness of 60mm, therefore it is recommended for installation for those who do not want to overpay. For lovers of sound sleep, Rehau Intelio will be a real find: a five-chamber profile 86mm thick with a noise reduction coefficient of 36dB (without double-glazed windows).

In cold climates, the 86 mm Rehau Geneo will help save up to 80% of heat: the six-chamber design provides high tightness, maintains a huge gap between the temperature amplitudes in the room and outside the window, and also creates reliable protection against drafts, thereby maintaining comfort and coziness in indoors throughout the winter, even at -60 degrees. According to the manufacturer, all Rehau products have a minimum service life of 40 years, and some models even 60 years.
