Which window profile to choose. Which profile is better for plastic windows. Installation of steel layer

The loud slogans of numerous sellers of plastic windows confuse any buyer. Each manufacturer presents its products as the best. Is it really? The answer to this question is known to those who are familiar with the criteria for window profiles from.

The ability to notice the first signs of counterfeits is a guarantee of not becoming a prey for scammers.

They have entered the construction industry very firmly. Very soon, wooden windows will become a curiosity that you will rarely see anywhere. And there are explanations for this.

Advantages of plastic

Firstly, plastic is more cheap material than wood, secondly, it is convenient to use and thirdly, such windows are very easy to repair.

Replacing any part of a window: sash, glass, opening mechanism takes a couple of minutes, and therefore is inexpensive.

Technical characteristics of PVC windows

They are determined by the type of its profile, of which there are quite a lot. The facade of the windows may be exactly the same, but the functionality and quality are different, due to the structural profiles. Then, if there is a strong intention to purchase plastic windows, then which profile is better to choose?

Brands

Absolutely disgusting products from a company with famous name can't afford it. Most likely, these will be one-day companies.

Therefore, give preference to products from manufacturers who have experience and have compiled a list positive feedback. In addition, the risk of stumbling upon a low-quality product when choosing windows from a large factory is much less. Small firms are unlikely to purchase expensive productive and technological equipment.

REHAU windows

A very well-known manufacturer of plastic windows. Well-deserved reviews, minimum defects, constant training and improvement of our employees, innovative development of manufactured designs. They cooperate with enterprises only if the latter have good equipment.

Interesting! REHAU certified production facilities are constantly inspected. Therefore, the risk of buying a low-quality product from the hands of a company partner is very small.

VEKA

Also a representative of the German ones, loved all over the world. They produce white and colored profiles that are capable of not losing color after prolonged exposure. sun rays.

The seal is made of natural rubber and can withstand very low temperatures. Models are sold from 58 -90 mm thick. In the price category, VEKA and Rehau are approximately the same.

KBE

It ranks third in our ranking after the first two companies. There are minor drawbacks: the number of defects is slightly higher compared to previous giants, there may be delays in deliveries, they do not arrange checks for their partners.

However, the products of this company are considered environmentally friendly and are recommended for installation in kindergartens and hospitals. The service life of such windows is around 50 years. There are offers in both luxury and economy classes. The profile is available in widths from 58 to 70 mm.

Trocal

The company is one of the pioneers in production PVC profile. They offer a huge range of decorative options.

MOTNTBLANK, PROPLESS, BRUSBOX

These companies are still gaining their reputation. There are already reviews of their products on the Internet.

You can even choose a forum and ask the owners of such windows your questions. The main advantage here is the affordable price.

Which profile of plastic windows is better and why? After all, the profile is the key to durability and quality metal-plastic windows. Even if at first glance the profile of PVC windows looks exactly the same, in practice everything turns out completely differently.

What is a quality profile? What characteristics should it have? What technologies are used in production? Before choosing a glazing profile, it makes sense to get answers to all these questions.

Each profile from which plastic windows are produced must be certified. The most significant certificate is the certificate RAL, it provides comprehensive information not only about the type of product, but also about the place of its production. In other words, a profile of the same brand, but manufactured at completely different enterprises, does not always have such a certificate.

For example, distinguishing feature manufacturer window profile VEKA means the presence of a RAL certificate not only at the main German plant, but also at all subsidiaries, including Russian production bases in Moscow and Novosibirsk.

ISO9001:2000(quality management certificate) are received by productions that have a well-organized management system, which implies strict compliance with all economic, technological, and organizational requirements inherent in production in highly developed countries of the world.

Does wider mean warmer and more reliable?

PVC window profile width is one of the main characteristics. Most window manufacturers promise us a few extra millimeters to the standard profile width in advertising campaigns, but is there really any benefit from these millimeters?

Most often on the window construction market you can find the following basic offers:

58mm "classic" profile
60mm profile (for site construction)
70-80 mm profile with increased installation width (for high-rise construction)
90mm profile

Width 58 millimeters is determined by the “classics” - wooden frames which replaced plastic windows. Today, a 58 mm profile freely allows us to produce modern, warm window designs that satisfy the requirements of the vast majority of buyers living in a wide variety of climatic zones.

Please note: subject to proper production and installation, this window profile rightfully deserves to be called the best for any room.

70 millimeters- a proposal that first appeared in the distant 80s. This profile has higher sound-proofing and heat-insulating characteristics; it is revered among the residents of Russia.

90 millimeters– a product considered premium. This proposal appeared no more than five years ago. A profile of this width allows the use of double-glazed windows up to fifty millimeters thick, and today it is the unsurpassed leader among all window profiles with high energy-saving performance.

Of course, even 90 mm today is far from the limit. Russian market today offers such profile systems, the width of which is 104, 124 mm. What does this give? If “classic” profiles allow you to install double-glazed windows with a width of no more than 32 mm, then, for example, 70 mm allows you to install a 42 mm double-glazed window, and a 90 mm profile allows you to install a 50 mm double-glazed window, and so on.

In many ways, the choice of window profile width depends on where it will be installed, for example, in country house, in the office, in the vestibule door or front door store Climatic conditions are also an important factor.

Number of cameras

When understanding the question of which profile of plastic windows is better, you should also pay attention to the number of cameras in the profile being evaluated.

The number of chambers in a plastic profile is the second most important characteristic when choosing window design. The first chamber is necessary for proper removal of condensate, the next is for the reinforcing metal liner, the third is necessary for high-quality fastening of the fittings elements, to create an additional layer of air for the purpose of high tightness of the window.

Thus, a standard metal-plastic profile must have at least three chambers for normal operation. Plastic window profile thickness completely determines the number of cameras in it. The 58 mm profile can have a maximum of three cameras, while the 70 mm profile can have four. The norm for a 90mm profile is six cameras.

It is worth noting that increasing the number of cameras with the same width of the window profile can only slightly change the characteristics of the entire structure. In order to increase heat-saving characteristics, it is recommended to choose a wider profile, not a larger number of partitions.

To the post "Which profile of plastic windows is better? Choosing balcony glazing" 12 comments

The time has come when you need to make a choice of profile for glazing the balcony. There is a lot of scattered information on the Internet. The same article provides a full analysis of the features and recommendations for choice in various situations. She helped me decide. Double bag with an installation width of 70 millimeters, class A, manufactured by Veka.

When choosing a profile for glazing a balcony, you should decide for yourself what result you want to achieve. If you just want to protect your balcony from precipitation and wind, increasing the temperature inside by 5-10 degrees, then choose the simplest 3-chamber profile with an installation width of 58-60 mm with ordinary glass or single-chamber double-glazed windows. If you plan to insulate a balcony, then you should choose a profile with a width of at least 70 mm and a double-glazed window.

When we were choosing our windows, we chose Veka. I know there is triple glazing. In the office they told us about the size and number of cameras. Now I don’t remember how many there are. At first the sound insulation was good, then over time it became much worse. I don't know what this is connected with. Now we are going to glaze the balcony and have not yet chosen a profile. But I think we won’t take a very thick one. We don't need warmth on the balcony like at home.

VRT had never thought about window profiles before, never considered their advantages and disadvantages, but in vain. IN old apartment They installed plastic windows at random, themselves, and as a result they did not provide any soundproofing or insulation. Afterwards, one acquaintance, seeing them, explained the features of the profiles. In the near future we will install others produced by Rehau.

We were finally ready to paint our balcony. I would like to choose a reliable company and not overpay. Can you please recommend a good company for glazing balconies? We ourselves came across the Rassvet window company (okna-rassvet_ru). Maybe someone has already encountered this company and can leave a review about their work?

Plastic windows firmly occupy the leading position. They differ the highest level heat and sound insulation, in addition, they give the possibility of choosing fittings, the method of opening the window and the color of the profile. It is also possible to choose a double-glazed window with the required number of cameras. However, not many people think that a specific window profile guarantees the strength and durability of the entire system. In this article we will compare plastic window profiles that differ in features and manufacturers.

General information about the profile of plastic windows

On average, the profile thickness of plastic windows varies from 58 mm to 86 mm, but some companies create a product with a width of 127 mm.

Its internal shot is hollow, but is separated by bridges, creating a number of light chambers. A special industrial calculation describes their dimensions and placement. The more spacious the profile, the more it contains the number of chambers that increase heat-saving characteristics. Another feature of the profile system is the width of the filling, which describes what type of double-glazed windows can be defined in the profile. They come in one- or two-chamber type, the width of the glass in a regular double-glazed window is 4 mm (grade M1).

Any cavity has a similar purpose:

for draining water;
fastening accessories;
gives an answer for strength, etc.

Profile paint can be varied; colors are applied using several methods:

co-extrusion method - multilayer films create a certain barrier that allows the product to endure dynamic overloads without defects;

lamination - imitating the structure, for example, marble or wood;
monochromatic coloring.

Properties of PVC profiles for plastic windows

Material

This piece is made from a variation of plastic - snow-white polyvinyl chloride.
The material used is distinguished by its highest resistance to chemical action by alkalis, solvents, acids and mineral oils.
It is harmless to humans and the surrounding environment.

Polyvinyl chloride, due to its characteristic properties, makes it possible to produce frames for double-glazed windows that are not only rectangular or square shape, however, also in the form of arches, triangles, circles and so on. Thus, giving any elementary or complex configuration to the window, allowing even the most extraordinary ideas of artists and architects to be realized.

Design

The internal grain of the plastic profile body is divided by longitudinal fences; in their own order, they form cavities (weightless chambers). The smallest number of chambers in the profile is 3, the largest is 8. The number of chambers describes the level of thermal insulation and sound absorption of the window; the lighter the cavities, the greater these characteristics. It should be immediately noted that 3- and 5-chamber profiles are used for their reputation.

Reinforcement

To provide rigidity, the profile is specially reinforced. The iron base guarantees the required strength of the system and the inviolability of the window during operation. To reinforce the profile, zinc-coated steel is used, so it does not deform in any way due to temperature changes or other actions of the surrounding environment.

L-shaped reinforcement category - an iron insert is installed along two walls;
U-shaped reinforcement discharge, where the alloy increases 3 walls;
Hidden reinforcement discharge - an iron insert is placed along 4 walls.

For window systems that have double-glazed windows with a volume of 1900 mm in height, a U-shaped reinforced profile is suitable. But for plastic windows of huge dimensions, for example, for a terrace or balcony, you need a profile with closed reinforcement.

Profile class

The thickness of the profile walls describes its accessory to a specific class:

Class A - the thickness of the profile walls must be at least 3 mm;
Class B - profile in which the wall thickness is from 2.5 mm;
Class C - non-standardized wall thickness.

As a result, the width of the profile of plastic windows directly depends on its class. The larger it is, the correspondingly more spacious the profile.

Comparison of manufacturers of plastic window profiles

On the Russian market, almost all both Russian and foreign manufacturers offer their own products. The leading positions in the ranking of profiles for plastic windows are occupied by the following companies:

Germany - REHAU, VEKA, KBE, SALAMANDER, SCHUCO, KOMMERLING;
Slovakia - INTERNOVA;
Korea - LG CHEM;

PROPLEX

The plant located in Podolsk produces the profile on German equipment in accordance with Austrian technologies.
This product is manufactured in widths that range from 58 mm to 127 mm, chambers from 3 to 6.
The unique recipe allows us to produce high-quality profiles characterized by impact strength and special whiteness.

You can also compare the properties of plastic window profiles using the tables presented below.

Profiles of the German company KBE

They say that German profiles of plastic windows are superior to the products of other manufacturers in terms of quality, whiteness of color, and technical features. They do not lose their characteristics in any way, even during a long service life; they can withstand virtually all kinds of dynamic overloads and significant temperature changes (from -50°C to +50°C).

The KBE company manufactures and supplies 2 types of more required profiles: KBE Ideal and KBE Specialist.

KBE Ideal - three-chamber profile

Mounting width is 58 mm;
latitude external walls- 3 mm;
the thickness of the glass unit can be 34 mm;
3 chambers in the rim, sashes, impost (horizontal and vertical window bars);
can be used in severe conditions (-60°C);
service life - 40 years;
The production uses environmentally friendly materials and does not contain lead.

Pros:

with a profile width of 58 mm, it has 3 weightless chambers, their size and excellent condition guarantee resistance to heat transfer. These windows have the highest level of density, which exceeds the existing GOST requirements by 5 (!) times, as if guaranteeing a complete absence of dust and drafts in the room;
2 hermetic sealing gaskets guarantee good sound insulation (46 dB each). The profile is especially equipped with horizontal jumpers, thereby increasing the strength of the lock when closing the window;
The KBE profile is equipped with stiffening ribs, which guarantee additional strength of the window system. The hardness can also be increased by special stops, with the support of which a clear placement of the reinforcing iron insert is achieved.

KVE Specialist - five-chamber profile

The installation width is the same 70 mm;
width of external walls - 3 mm;
the thickness of the glass unit is 42 mm;
5 chambers in the rim and sashes, 3 or 4 in the impost (horizontal and vertical window bars);
Benign for use in severe conditions (-60°C);
seal silhouettes are suitable for class A;
service life - 40 years;
During production, environmentally friendly materials are used, and do not contain lead in any way.

A five-chamber building allows for the best possible thermal insulation; this profile can retain heat 20% more than conventional three-chamber systems. It is possible to achieve excellent sound insulation by installing large double-glazed windows in a 70 mm profile;
The 13 mm profile groove allows you to install anti-burglary fittings, thereby ensuring the safety of the building;
KBE profile The specialist has additional horizontal jumpers, thanks to which the handles and hinges will become firmly fixed;
with the device, the prefabricated seam is approximately 20% more spacious, allowing for additional insulation in its own right.

Approximate price of windows from KBE profile

An important reason when choosing this or another double-glazed window is its cost. It is often considered decisive, but German window profiles of the highest quality cannot be inexpensive. Below is the approximate market price in Russia.

On average, a single-chamber double-hung window with a volume of 140x130 cm, in which 1 sash has a dull appearance and the other is tilt-and-turn, will deserve:

from a 58 mm profile from RUB 7,500,
from 70 mm - from 10,000 rub.

The cost of a two-chamber three-leaf window with a volume of 140x203 cm, in which the 1st sash is rotary, the central one has a dull appearance, the 3rd one is tilt-and-turn, will be from:

from 58 mm profile 13,000 rubles;
from 70 mm 14500 rub. and more.

When purchasing a balcony block with a drop-down door with a volume of 210x67 cm and a blind window - 140x136 cm, you need to pay no less than:

from profile 58 mm 10500 rub.
from 70 mm from 12,000 rub.

What to focus your interest on when choosing a plastic profile with double-glazed windows

To find the required profile thickness, you must have basic knowledge about double-glazed windows, since up to 70% of heat losses occur specifically through it.

This colorless substance consists of 2 or more glasses, which are hermetically combined with the frame. Between them a room appears (a light strip), filled with rarefied air or an inert gas, such as argon or krypton. This type of filling is used in the production of energy-saving double-glazed windows.

A single-chamber double-glazed window is a system of 2 glasses of 4 mm each and a weightless layer of 16 mm; in its incomplete form it is classified - 4-16-4. Thus, its installation width is the same 24 mm. The system, the same 36 mm, comes out of a two-chamber double-glazed window, which consists of 3 glasses of 4 mm each and 2 layers of 10 mm each - 4-10-4-10-4.

Consequently, an appropriate profile is selected for the required double-glazed window. For example, optimal solution For ordinary apartment or at home, a 5-chamber profile with a 70 mm installation width and a 30 mm double-glazed unit will serve, where a heat-reflecting coating should be applied to one glass.

If the windows face the north side and there is a busy road nearby, then the following option is suitable in this case: a 5-chamber profile with a depth of 86 mm, supplemented with a 32 mm double-glazed window with a protective noise-insulating film.

When a balcony (gallery) is connected to an adjacent space or it is planned to make a small office (rest room) out of it, then the profile must be 5-chamber with an installation depth of 86 mm, and the double-glazed window must be energy-saving, two-chamber with a width not less than 40 mm.

For conventional insulation of a balcony, a 60 mm 3-chamber profile and a 30 mm single-chamber double-glazed window are suitable.

However, it’s not enough to simply choose the best PVC profile and double-glazed window. It is no less important to entrust the installation of finished windows to experts. Otherwise, no matter how precious the system may be, a bad installation will nullify all its highest properties.

We will analyze each type of profile, and also describe the properties in more detail so that you can make a choice better side and so that plastic windows will delight you for many years.

Advantages of modern plastic windows over former ones wooden structures many understood. Plastic windows are incomparably more airtight than wooden ones, which ensures good thermal insulation and sound insulation of the windows, and also prevents the entry of unpleasant odors from the street.

Even double-chamber plastic windows are much warmer than wooden ones; their installation will lead to a significant reduction in heat loss, which means savings. How to choose the right window profile and purchase best windows so that the price matches the quality. This article will help you understand this issue.

Helpful information:

In addition, the preservation of heat in the apartment, of course, depends on the plastic window itself, namely on its quality. However, the installation of PVC windows also plays an important role.

The profile for a PVC window now meets certain standards, and the best among them simply does not exist. It is divided into three classes: “Economy”, “Standard” and “Premium”. The main thing is that there is a difference between classes, but within a class there is absolutely no difference.

“Economy” is the main task of the window, to show that it is plastic. There are no advantages or disadvantages to such a profile. Such windows are installed in most new buildings. At the same time, according to experts: windows from the economy class profile belong in the trash container.
“Standard” – has optimal ratio prices and quality. That is, these are windows whose quality is already high, but at the same time there is no inflated self-esteem. This type profile complies with the Euro standard when performing renovations in apartments. The profile has elastic seals, durable fittings and excellent appearance.
“Premium” – primarily emphasizes the status of the owner, for those people who do not have a limit on their family budget.

All the stories about how my profile is whiter, and mine is warmer, and mine is straighter are just a marketing ploy, or an attempt to extract as much money from you as possible.

Sealing of double-glazed windows

The double-glazed window is not part of the window profile, but the assembly of the window as a whole depends on the quality of its seal. Here, when choosing, you need to take into account several circumstances:

Even in a budget window, the sealing collar should be without cuts and solid. The cut does not affect heat transfer, but will serve as a kind of nursery for the breeding of infection, as with a single seal. Many people recommend sealing the cut with silicone, but due to thermal deformations, microcracks will soon appear.
The seal of the frame and glass unit itself must be rubber. Manufacturers often install polyurethane expansion joints; when the window is deformed, they flatten, which leads to sagging of the glass unit in the frame and all the problems described above appear. Will have to do it more often.

A few words about window fittings

When choosing high-quality plastic windows, in addition to the above profiles and double-glazed windows, you need to pay attention to the window fittings, which must be manufactured according to uniform European standards. Then, in any weather, there will be no problems with opening/closing the window.

The fittings should not oxidize or rust. In the window design, all hinges must be hidden, which means the profile should not allow water to flow in. If there is a single seal, condensation will still collect on the hinges, so the seal must be double.

The window frame should have adjustable ventilation slots, thanks to which the window itself will open less, which will increase the service life of the plastic window.

Whose window profile is the best?

It is important to know the manufacturer of plastic windows that value their name. This, of course, serves as an additional guarantee of the quality of the windows.

There is a huge number of companies producing window profiles on the market. The most famous: Montblanc, Salamander, Aluplast, Velux, Exprof, Provedal, Gealan, Vitrage, Brugmann, Veka and others. They have gained their authority through the production of high-quality windows.

The first series of PVC windows was released in Germany. To this day, German profiles, in particular KBE and Rehau, are very popular among buyers. Below we will try to compare the profiles of plastic windows from some leading manufacturers and note their advantages and disadvantages.

At the KVE profile There are three main modifications from German manufacturers: a budget option"Expert", best option“Extra” and the more expensive energy-efficient option “Etalon”. All KBE profile windows are very durable, aesthetically pleasing, environmentally friendly, have high levels of sound and heat insulation, are resistant to various temperature fluctuations, are easy to maintain, and climate control systems in the “Etalon” modification can be used. The minimum price for this profile starts from 12 thousand rubles. The disadvantages of the KBE profile include it grey colour, which does not always harmoniously suit the interior of the room.

Very popular nowadays REHAU profiles, also from German manufacturers. Such profiles are very aesthetic, durable, environmentally friendly, also easy to maintain, have low thermal conductivity, such structures can be equipped with special system locking, which will make it impossible to enter the room through the window. Also, these profiles have a very convenient climate control function. The price for these profiles starts from 13.5 thousand rubles. A minor drawback is that the reinforced chamber has small size, and, as a result, the height of the window sash decreases.

Veka profiles were very common in our country and have already proven their durability. However, recently the demand for these profiles has dropped significantly. This happened after the discovery of elevated levels of lead in the profiles, which negatively affects people's health.

Profiles of the Belgian concern Deceuninck have proven themselves to be reliable and excellent quality. Two types of profile data are offered: “Favorite” and “Bautek”. The profiles are popular in the modern construction market and are not inferior in all respects to premium systems. The price of these profiles is from 14.5 thousand rubles. The disadvantages include the fact that the Bautek system is not suitable for every home.

It is not uncommon that sellers only know the name of the manufacturer’s company, and in technical specifications the window profile itself is completely incomprehensible. This is where the lies begin: cheaper goods are passed off as higher quality and more expensive.

When choosing, remember that the best manufacturer simply doesn’t exist, don’t be fooled by the seller’s persuasion to buy a better profile - check exactly the class. Otherwise, you will be sold an “Economy” class profile with a single seal at the price of the “Standard” class. Choosing a profile for a window is not only about the quality of the window as a whole, but also comfortable accommodation in an apartment where good plastic windows are installed.

Now, based on the material presented, and paying attention to the advantages and disadvantages of profiles from well-known companies, you can try to choose high-quality plastic window profiles that are suitable specifically for your home.
