PVC profile for BauLine plastic windows. Types of window profiles and their characteristics PVC profiles

Miser pays twice

The cost of a window from a profile of well-known brands is a priori higher than other manufacturers. Which profile is better to choose for a plastic window? Is it worth paying extra for famous brand Or can you save?

Which profile is better to choose for windows - a brand or not a brand?

The word "brand" is associated among buyers with high quality, which can be trusted. Brand reputation is not an empty phrase, it is always backed up by solid investments in Scientific research, first-class equipment, highly quality materials, employee training and communication campaigns. No self-respecting manufacturer will invest in advertising a product whose quality is not certain.

The window market is highly competitive. In the struggle for a client, the price is increasingly becoming the only argument, and window manufacturers are more willing to offer an economy class profile.

“It’s the same, only cheaper, without overpayment”– can be heard in sales offices. Are all profile systems really the same and the difference lies only in the promoted brand?

If choice plastic windows limited only by the price factor, the result will be obvious - the buyer will choose the most cheap option and other arguments will be powerless. Operating only with low cost is not an approach for thinking people who know how to count their money. Why are windows from well-known and reputable profile manufacturers more expensive? What can manufacturers save on for the sake of low cost? Which profile is better?

What is a window profile and what is its role in a window?

First, let's look at what a window profile is and what role it plays in a window. The window profile is plastic frame and a window sash, into which steel reinforcement, double-glazed windows, fittings and seals are installed. The main task of the PVC profile is to give shape and maintain a strong frame window construction. The wider the profile, the more options the window can have - better sound insulation, security and heat saving.

Which window profile is better to choose - what manufacturers save on

The basis of the quality of any product, whether it be bread or a window profile, is made up of high-quality ingredients and compliance with production technology. Of course, any manufacturer is interested in reducing the cost of production. But well-known and proven brands cannot reduce the cost of the recipe by reducing the quality.

Laboratories of major manufacturers are constantly working to improve the mixture. It is impossible to make a recipe once and for all - new technologies appear, raw material suppliers change, product requirements become more stringent. Any change in the recipe at a major manufacturer is confirmed by a comprehensive check.

A decrease in the composition of expensive components - PVC-S, impact modifiers, titanium dioxide (color catalyst) leads to a decrease in the durability of the profile. It happens that the window does not survive the first frosty winter or is deformed on a hot day.

● Brittleness or fluidity instead of strength - savings on recipe

To reduce the cost of a window profile, manufacturers most often increase the content of hydrophobic chalk from the permissible 8 parts to 30, and sometimes even up to 40, to the detriment of the PVC content. This saving leads to increased brittleness and the appearance of cracks in the profile or in the places where corners are welded. Cracks on a fragile window profile can appear both during transportation and 1-3 years after window installation. There is only one way to eliminate the marriage - by replacing the window.

Replacing expensive polyvinyl chloride in the PVC profile with monosyllabic acids makes the profile too plastic. Warming up in the sun, it can “melt”, irrevocably losing its shape. As a result - non-opening, jammed sashes, cracked double-glazed windows and the need to replace the window.

● Window profile turns yellow - savings on additives

Plastic windows firmly occupy a leading position. They differ high level heat and sound insulation, in addition, they provide the opportunity to choose fittings, the method of opening the window and the color of the profile. You can also choose a double-glazed window with the required number of cameras. But few people think that it is the window profile that ensures the strength and durability of the entire structure. In the article, we compare plastic window profiles of different characteristics 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 produce products up to 127 mm wide.

His inner part hollow, but separated by bridges that create several air chambers. A special technical calculation determines their size and location. The wider the profile, the greater the number of chambers in it that increase the heat-preserving properties. Another characteristic of the profile system is the filling width, which determines what type of double-glazed windows can be installed in the profile. They come in one or two chamber types, the width of the glass in a standard double-glazed window is 4 mm (M1 brand).

Each cavity has its own purpose:

• for the outflow of water;
• fastening accessories;
• responsible for strength, etc.

The color of the profile can be varied, the color is applied in several ways:

• co-extrusion method - multilayer films create a kind of barrier that allows the product to withstand dynamic loads without damage;

• lamination - with texture imitation, for example, marble or wood;
• monochromatic coloring.

Characteristics of PVC profile for plastic windows

Material

• This product is made of a kind of plastic - white polyvinyl chloride.
• The material is highly resistant to chemical attack by alkalis, solvents, acids and mineral oils.
• It is harmless to humans and the environment.

• Polyvinyl chloride, due to its distinctive properties, makes it possible to manufacture frames for double-glazed windows not only in a rectangular or square shape, but also in the form of arches, triangles, circles, and so on. Thus, giving absolutely any simple or complex configuration to the window, allowing you to translate into reality even the most non-standard idea designers and architects.

Design

The inner part of the plastic body of the profile is divided by longitudinal partitions, which in turn form cavities (air chambers). The minimum number of chambers in the profile is 3, the maximum is 8. The number of chambers determines the degree of thermal insulation and sound absorption of the window, the more air cavities, the higher these figures. It should be noted right away that 3- and 5-chamber profiles are popular.

Reinforcement

To give rigidity, the profile is additionally reinforced. Metal carcass provides the necessary structural strength and reliability during operation of the window. Galvanized steel is used to reinforce the profile, so it does not deform under temperature changes or other environmental influences.

• L-shaped type of reinforcement - a metal insert is installed along two walls;
• U-shaped type of reinforcement, where the metal reinforces three walls;
• Closed type of reinforcement - a metal insert is located along four walls.

For window structures that have double-glazed windows up to 1900 mm in height, a U-shaped reinforced profile is suitable. However, for plastic windows of large dimensions, for example, for a loggia or a balcony, a profile with closed reinforcement is required.

Profile class

The wall thickness of the profile determines its belonging to a certain class:

• Class A - profile wall thickness must be at least 3 mm;
• Class B - profile, where 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 higher it is, the correspondingly wider the profile.

You can also compare the characteristics of plastic window profiles according to the tables below.

Profiles of the German company KBE

It is believed that the German profiles of plastic windows are superior to the products of other manufacturers in terms of quality, color whiteness, and technical characteristics. They do not lose their properties even during a long service life, perfectly withstand almost any dynamic load and significant temperature changes (from -50°С to +50°С).

The KBE company manufactures and supplies 2 types of the most popular profiles: KBE Etalon and KBE Expert.

KBE Etalon - three-chamber profile

• The mounting width is 58 mm;
• the width of the front walls - 3 mm;
• the thickness of the double-glazed window can be up to 34 mm;
• 3 cameras in the frame, sashes, impost (horizontal and vertical window bars);
• can be used in harsh conditions (-60°C);
• service life - 40 years;

Advantages:

• with a profile width of 58 mm, it has 3 air chambers, their size and optimal position provide resistance to heat transfer. Such windows have a high degree of tightness, which exceeds the existing requirements of GOST by 5 (!) times, which guarantees the complete absence of dust and drafts in the room;
• two sealed gaskets provide excellent sound insulation (up to 46 dB). The profile is additionally equipped with horizontal lintels, thereby increasing the strength of the lock when the window is closed;
• stiffening ribs are installed in the KBE profile, which provide additional strength to the window structure. Also, special stops allow to increase the rigidity, with the help of which the exact location of the reinforcing metal insert is achieved.

KBE Expert - five-chamber profile

• 13 mm profile groove allows you to install anti-burglary fittings, thereby ensuring the safety of the room;
• the KBE Expert profile has additional horizontal bridges, thanks to which the handles and hinges will be securely fastened;
• when installed, the mounting seam is wider by about 20%, in turn allowing for additional insulation.

Estimated cost of windows from KBE profile

An important factor when choosing one or another double-glazed window is its price. Often it is decisive, but high quality German window profiles cannot be cheap. Below is the approximate market value in Russia.

• On average, a single-chamber double-leaf window with dimensions of 140x130 cm, in which one sash is of a deaf type, and the other is a tilt-and-turn one, will cost:
  • from a profile of 58 mm from 7500 rubles,
  • from 70 mm - from 10,000 rubles.

• The price of a two-chamber three-leaf window with a size of 140x203 cm, in which the first sash is rotary, the central one is of a deaf type, and the third one is tilt-and-turn will be from:
  • from 58 mm profile 13,000 rubles;
  • from 70 mm 14500 rub. and higher.

• When buying a balcony block with an opening door measuring 210x67 cm and a blind window - 140x136 cm, you will have to pay at least:
  • from a profile of 58 mm 11,000 rubles;
  • from 70 mm from 13000 rub.

What to look for when choosing a plastic profile with a double-glazed window

In order to determine what profile thickness is needed, one should have basic knowledge about a double-glazed window, because up to 70% of heat losses occur through it.

This transparent element consists of 2 or more glasses that are hermetically connected to the frame. Between them, a chamber (air gap) is formed, filled with rarefied air or an inert gas, such as argon or krypton. This kind of filling is used in the production of energy-saving double-glazed windows.

A single-chamber double-glazed window is a design of 2 glasses of 4 mm each and an air gap of 16 mm, abbreviated as 4-16-4. Thus, its mounting width is 24 mm. A construction equal to 36 mm is obtained from 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.

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

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

When a balcony (loggia) is combined with an adjacent room or it is planned to make a small office (rest room) out of it, then the profile should be 5-chamber with an installation depth of 86 mm, and the double-glazed window should be energy-saving, two-chamber with a width of at least 40 mm.

For simple insulation balcony fit 60 mm 3-chamber profile and 30 mm single-chamber double-glazed window.

But it is not enough just to choose the optimal PVC profile and double-glazed window. It is equally important to entrust the installation of the finished window to professionals. Otherwise, no matter how expensive the design is, poor-quality installation will cancel all its high characteristics.

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

The advantages of modern plastic windows over the former wooden structures understood by many. Plastic windows are incomparably more hermetic than wooden ones, which ensures good thermal and sound insulation of the window, and also does not get inside unpleasant odors from the street.

Even two-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 to match the price with the quality. This article will help you sort out 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 PVC window profile now complies with certain standards, and the best among them simply does not exist. It is divided into three classes: "Economy", "Standard" and "Premium". The point is, 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 and disadvantages to such a profile. Such windows are installed in most new buildings. At the same time, according to experts: windows from an economy class profile have a place in a garbage container.
• "Standard" - has an optimal ratio of price and quality. That is, these are windows, the quality of which is already at its best, but at the same time there is no overestimated self-esteem. This type of profile corresponds to the euro standard for repairs 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 the family budget.

All the stories about the fact that my profile is whiter, and mine is warmer, and mine is smoother is just a marketing ploy, or an attempt to get as much money out of you as possible.

Sealing of double-glazed windows

The double-glazed window is not part of the window profile, however, the assembly of the window as a whole depends on the quality of its sealing. Here, when choosing, you need to consider several factors:

• Even in the budget window, the sealing cuff should be uncut and solid. The cut does not affect heat transfer, but will act as a breeding ground for infection, as with a single seal. Many recommend sealing the incision with silicone, however, with temperature deformations, microcracks will soon appear.
• The seal of the frame and the double-glazed window itself must be rubber. Often, manufacturers install polyurethane expansion joints, they flatten when the window is deformed, which leads to sagging of the double-glazed window in the frame and all the problems described above appear. Will have to more often.

A few words about window fittings

When choosing high-quality plastic windows, in addition to the above profiles and double-glazed windows, it is necessary to pay attention to 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.

Hardware should not oxidize or rust. In the window device, all hinges must be hidden, which means that the profile must not allow water to flow. 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 life of the plastic window.

Whose window profile is the best

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

There are a huge number of window profile manufacturing companies on the market. The most famous: Montblanc, Salamander, Aluplast, Velux, Exprof, Provedal, Gealan, Vitrage, Brugmann, Veka and others. They have gained their credibility through the manufacture of quality windows.

The first series of PVC windows was produced 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 KBE profile from German manufacturers there are three main modifications: a budget option"Expert", the optimal option "Extra" and the more expensive energy-efficient option "Etalon". All KBE profile windows are very durable, aesthetic, environmentally friendly, have high performance sound and heat insulation, resistant to various temperature fluctuations, easy to maintain, 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 its gray color, which does not always harmoniously fit the interior of the room.

Very popular at present 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 a special locking system that 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 disadvantage is that the armored 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, in recent years, the demand for these profiles has fallen significantly. This happened after the discovery in the profiles of high lead content, which negatively affects people's health.

Profiles of the Belgian concern Deceuninck have proven themselves for their reliability and excellent quality. There are two types of these profiles "Favorite" and "Bautek". Profiles are popular in the modern construction market, they 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 they do not understand the technical characteristics of the window profile itself. This is where the lies begin: a cheaper product is passed off as a better and more expensive one.

When choosing, remember that the best manufacturer simply does not exist, do not be fooled by the persuasion of the seller to purchase the best profile - specify 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 the quality of the window as a whole, but also a comfortable stay in an apartment where good plastic windows are installed.

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