Which profile is better to choose plastic windows from? Characteristics and types of window profiles Normal profile for a plastic window

Profile selection is not the same simple task, as it may seem. The question is, which profile to choose for plastic windows? , quite relevant. Exists a large number of options. Range of materials for construction market very large, so without precise knowledge of the profile features it is easy to get confused. You can choose not only among dozens of manufacturers, but also among hundreds of models produced by one company.

What to look for when choosing a profile

The profile for plastic windows is one of the most popular. Every self-respecting company produces products from it. It is worth noting that most import companies have their production in Russia.

Each window consists of glass, double-glazed windows, profile systems, and fittings. The profile inside is empty. There should only be partitions inside, creating separate chambers that are filled with air; Some manufacturers make the structure airtight and pump nitrogen into it. It is believed that such a window profile will better retain heat in the room, and the glass will not fog up.

The number of chambers, no matter what they are filled with, affects the profile’s ability to retain heat - the more there are, the warmer the material. In Russia, designs with 3-5 chambers are most often used, with a profile thickness of 60 mm. This material is relatively inexpensive and can withstand severe frosts.

The note: Manufacturers achieve a variety of colors by heating a special film onto products. It cannot be peeled off. No fading or blistering will occur over time.

Selection of profile and glass design

From quality PVC depends on how long the product will last, how it will cope with weather conditions, how attractive it will be appearance. The best windows PVC must meet GOST standards and have the necessary certification.

In fact, there is no particular difference which company produces the product. In order for the structure to have sufficient rigidity, reinforcement is carried out. Steel is used for this. The core made of it has the shape of the letter P, or can be a closed oval with a square cross-section. The window profile in this case will be a little more expensive, as it has increased strength.

The double-glazed window is a sealed structure. It may include a different number of glasses. Usually there are two or three. There may be inert gas or rarefied air between the glasses if the design option is cheaper. The number of chambers of a double-glazed window is calculated relative to the free air spaces: if there are two glasses, the double-glazed window is single-chamber, if there are three, it is double-chambered. There are products with five chambers, but they are quite rare.

Double-glazed windows can differ in thickness: the thicker it is, the heavier the product, but the higher its ability to insulate noise. The minimum thickness of quality glass is 4 mm.

There is energy-saving glass: the peculiarity is that, with a relatively small thickness and weight, the double-glazed window has high insulating properties and can replace a three-chamber double-glazed window, surpassing it twice in quality. The price for such a product is slightly higher.

It is worth noting the reduced weight of such a window, which is quite important if the wall structure has a weight limit. The fittings will also experience less stress and will be able to work longer without replacement.

When choosing plastic windows, the profile must be considered first, but it is also worth taking a closer look at the glass itself. There is a wide variety of glasses that differ from each other in technical characteristics and cost. For example, there are reflective glasses - they can protect the room from excessive sunlight, make it cooler. There are extra-strength glasses, and if you have children, it makes sense to install just the right kind so that they don’t accidentally break. High-strength or mirror glass is also suitable for residents of the first floors. Such material will not only protect the window from mechanical damage, but will also save you from prying eyes.

Window profiles last a long time, and over the period of their existence the sash endures at least 50 thousand openings. The fittings must be able to withstand such loads without problems.

Choosing a plastic window manufacturer

There are quite a few companies producing plastic windows on the market. The most popular brands are:

• Rehau;
• Novotex;
• Veko.

Each of them has its own distinctive features. Rehau is considered a leading manufacturer whose quality is looked up to. The products are carefully checked at the factory and have high performance characteristics. The average price for products is from 6 thousand.

Veko is a company of German origin. Products can be recognized by their perfectly smooth, clean plastic white. profile reinforcement is always closed. The plastic is 3 mm thick, and each bead has a company logo. Average price is from 7.5 thousand rubles.

KVE is also a German brand. In Russia it is very popular. The range of products is very wide - from one- to five-chamber structures of any size and type. Prices start from 5 thousand rubles.

Novotex- a domestic company. It produces high-quality plastic using KVE-Etalon technology. Specifications are not inferior to European ones, but the average price for products starts from 3.5 thousand rubles.

Thinking about which window profile to choose , it is necessary to take into account the characteristics of your region. If cold weather prevails, it is better to purchase a thicker glass unit. If your place is relatively warm in winter, then there is no point in overpaying.

Everyone bases their choice of manufacturer mainly on the cost of the product of interest and trust in a particular brand. The companies listed above produce products of similar quality, which can be equipped with different accessories, due to which the cost can be higher or lower.

Profile classification

You can find profiles of various classes on sale, most often these are A and B. Let’s consider this issue in more detail so that it is clear what this means.

• “A” class includes products whose outer wall has an additional thickening. This extends to doors as well. Such products have a RAL certificate.
• Class “B” includes a lightweight profile; it has a thinner outer wall.

As you can see, these types of products are distinguished by strength and weight, but not by quality.

Class B is slightly cheaper, however, when choosing profile types for plastic windows , take into account the characteristics of your structure and the climate of your region.

Class B profile is well suited for glazing unheated balconies and loggias; its installation is relevant for summer houses, since this product is small in thickness and is not capable of retaining heat in the room efficiently. The sound insulation will be worse, but such a design will be able to protect from rain and wind. Its light weight is also important.

Which profiles are most often chosen?

Many buyers believe that the thicker the window, the better, since it is more reliable. But is it? Let's try to figure it out!

• Classic, 58 mm wide.
• 60 mm, used on large construction sites.
• 70-80 mm, most often found in high-rise buildings.
• 90 mm – reinforced.

58 mm - this was the width that the wooden windows. After the appearance of plastic analogues, according to tradition, the width did not change. It is sufficient to ensure that the structure is sufficiently warm and durable and well insulates noise from the street. This profile is universal for any climate. With the right manufacturing technology, such a window is suitable for installation in any type of building on any floor. It is not very heavy, but has high strength.

The profile thickness of 60 mm is mainly an advertising gimmick, and products with it are not much different from those presented above.

70-80 mm already has significant differences from other models. It is able to better isolate sound and does a good job of retaining heat indoors. Most often this profile is used by residents middle zone Russia, since the winters there are more severe than, for example, in the southern part of the country. .

90 mm: this design appeared relatively recently. Has high strength and good sound and thermal insulation properties. This profile effectively saves energy heating devices, however, it has a large mass and is not suitable for all types of residential buildings.

The difference begins to appear after a few years (sometimes within a year), when the frame and sashes become deformed - they are difficult to open and close, there is wind from the street, condensation appears between the glass panes, and then black mold.

Therefore, it is very important to know the criteria to avoid fakes when choosing a profile for plastic windows.

Types of profiles and their classification

Main structural element The profile serves as a profile for the doors and frames. It determines not only the aesthetic perception of the window, but also its strength characteristics and service life. European standard EN 12608 SR and GOST 30673-99 profiles made of polyvinyl chloride are classified according to several parameters.

1. Thickness of outer walls. The profile is a closed hollow structure with a system of partitions inside. All the main components depend on the thickness of the walls that form the structure. consumer properties windows: cost, strength and durability.

The European standard distinguishes the internal and external walls of a plastic profile. The internal ones include all the outer walls of the profile that are invisible to the eye in an already installed window. From the first definition it logically follows that the outer (outer) walls are the front walls of the window and are visible both from inside the room and from the street (see photo).

Depending on the thickness of polyvinyl chloride in the external and internal walls, three classes of profiles are distinguished (in this regard Russian standard more rigid):

• "A"— the thickness of the external walls is >= 2.8 mm, the internal ones >= 2.5 mm according to the European standard (minimum 3.0 mm at the outer wall according to GOST), which ensures high level window strength, best heat and sound insulation;
• "IN"— the outer walls have a thickness of 2.5 mm, the inner walls have a thickness of 2.0 mm (in line with GOST). A profile of this class retains heat 10-15% worse, is 12-17% less resistant to various types of deformation, and blocks street noise 10-20% worse;
• "WITH"— the European standard and GOST do not impose certain requirements for this class of profile. It is mainly used to make windows for non-industrial facilities. A number of companies, meeting the requirements of one of the parameters of class B, which is important, make economy class windows for the population (in general, this is a class C profile).

Unscrupulous window installers, focusing on low price, persuade customers to install an “object” profile (class C, not a single parameter corresponds to classes A and B), intended for non-residential premises(in fact, the price is almost twice as high as the real one, but significantly lower than the cost of profile B).

Such windows do not retain heat and quickly become deformed. It is visually difficult to distinguish such a profile from a standard one (class B or A) - measurements with a caliper are required. The inscriptions on the profile can also help determine the quality of the proposed profile. protective film"object".

Attention: only if both parameters meet the requirements of the standard, the profile belongs to a certain class, which must be confirmed by the corresponding certificate. Without presenting documents confirming quality, it is better to refuse the transaction.

It is easier for consumers who understand profile classes to decide which plastic to choose for their windows.

2. By temperature zones. In Europe and Asia there are countries with very hot, temperate and cold climates. Window manufacturers took the current situation into account and produced their own line of products for each zone. In Europe it is tied to the hottest month of the year, in Russia - to January.

Depending on the average temperature in January, the profiles produced may be:

• lightweight version - for countries with hot climates, where the average temperature of the coldest month remains positive (must withstand short-term temperature drops down to -5 degrees Celsius);
• standard version - for zone temperate climate with an average temperature of -20 o C in January (the maximum permissible negative temperature is -45 degrees Celsius);
• frost-resistant - for Far North, where the temperature drops to minus 55 degrees Celsius.

The last two types are mass produced in Russia. Lightweight windows are produced only by the Russian company “Krauss” (Krasnodar) - they cover the entire south of Russia.

3. According to impact resistance, the profile is divided into class I and class II. Class I PVC must withstand the fall of a special striker weighing 1.0 kg from a height of 1.0 m at a plastic temperature of minus 10 degrees Celsius. For class II, the fall height is increased to 1.5 m.

This classification allows you to determine how correctly located internal partitions(they counteract the deflection of the outer walls into the structure under mechanical stress) and how plastic reacts to lower temperatures (everyone knows the property of plastics to become brittle in severe frosts).

Consumer properties of profiles that you need to pay attention to

Which profile to choose for PVC windows so that it is warm, quiet, airtight, inaccessible to burglary and, at the same time, not to contact scammers? The main characteristics will help with this.

System width

The first indicator you should pay attention to is the width of the profile structure. It depends on it how warm and cozy it will be in the apartment or wooden house. For consumers who are encountering plastic windows for the first time, it is difficult to understand how the width of the frame and sash affect the comfort in the room. Let's try to explain.

A double-glazed window is installed in the window sash, which consists of several glasses fixed around the perimeter with a PVC profile frame. The air pockets between the glasses are called chambers. In standard windows, there is simply air in them; in the “Premium” segment, inert gas is pumped into the chambers to improve all the characteristics of the double-glazed window.

From school physics lessons we know that air is a poor conductor of heat, and glass with an air pocket is a poor conductor of sound. Therefore, the more cameras in a double-glazed window and, consequently, the number of glasses, the more comfortable it is to stay in the room. Window manufacturers mainly offer classic version profile width is 58 mm, allowing the installation of single-chamber windows. For two cameras a minimum of 70mm is required.

For the regions of the Far North with their extreme temperatures Windows with three or even four chambers are offered. But this requires an appropriate profile width: 90 mm for 3 chambers, 110-120 mm for 4. This type products belong to the “Premium” class. Because of heavy weight It is not recommended to install such windows on balconies and loggias.

Number of profile cameras

The window design has two units with cameras. One is a double-glazed window, which is discussed above. The second is the profile itself. The profile is hollow. To create structural strength, fasten fittings and increase the level of heat and sound insulation, there are partitions inside the profile. The hollow volumes created by them are called chambers. The more there are, the better the performance of the window. The location of the jumpers is calculated mathematically - each of them performs a specific function.

On sale you can find 3-chamber profiles (this is the minimum possible number of cameras) and 7-chamber profiles. The most popular ones are 5-chamber ones. They offer the best combination of price and quality.

It is difficult to check the quality of the samples offered by the company by the installer, but you can pay attention to the little things that will say a lot:

• The company logo, date and place of manufacture applied to the protective tape will with a 90% probability confirm the origin of the product;

• The surface texture will also help: for high-quality windows, the surface of the plastic should be perfectly smooth. Graininess indicates the Chinese origin of the product or Russian handicraft production;
• The applied paint should be uniform in color and without streaks.

The market for plastic windows in Russia is opaque. But we have summarized the information obtained from the Internet and telephone surveys and present to the user a rating of plastic window brands available to Russian buyers. The following parameters were taken as a basis: market preferences of consumers in Russia, popularity among Internet users (based on the number of requests in search engines) and expert assessments.

Plastic windows with Internova profile

A significant argument in favor of Internova windows is the slow destruction of plastic under the influence of ultraviolet radiation. To achieve this effect, the company has developed and patented an exclusive formulation of plastic additives, which is kept secret.

Plastic windows in the house free you from many problems. They make you feel warm and cozy. They are easy to wash. They serve for a long time - up to 40 years. And if you take the cost, then wooden ones with double-glazed windows are twice as expensive. The profile is the main detail in the window, so you need to choose it carefully.

main part plastic window— PVC profile. The basis of this material:

• kitchen salt;
• oil;

In addition, there are additives that improve the quality of plastic, in the form of:

• stabilizers;
• modifiers;
• fillers.

A PVC profile for a plastic window is obtained by pressing the initial soft mixture through a special profiling mold with a given geometry.

Very important when comparing profiles of plastic windows, as well as the structure as a whole, is the coefficient that expresses the interdependence between the temperatures inside and outside on the plane of the window and the density heat flow which she misses. The relationship is inversely proportional: the coefficient increases - heat loss decreases. Unit of measurement: m2°C/W.

Key Feature

Products from different companies differ in the installation width of the profile of plastic windows, which is the main parameter of the profile. Most popular offers:

• standard or classic - 5.8 cm;
• added - 0.7 cm;
• increased - 0.9 cm.

How thick is the profile?

The designs differ not only in width, but also in the thickness of the profile of plastic windows. For example: if we take GOST 30673-99 standard, it puts forward the following requirements:

1. Class A:

• along the outer wall - 3.0 mm;
• on the inside - 2.5 mm.

2. Class B:

• 2.5 mm, 2.0 mm respectively.

3. Class C:

• both external and internal wall thicknesses are not standardized.

And in accordance with the RAL (Germany) standard, the outer wall should be 3.0 mm thick and the inner wall 2.5 mm. Tolerance - 0.2 mm in either direction. The European Industrial Standard for class A has the same requirements.

The concept of PVC profile rigidity for a plastic window

The window must withstand the following loads:

• static;
• dynamic.

Since the polyvinyl chloride, which is used to make the profile, is itself plastic, a reinforcing profile with a thickness of at least 1.5 mm is provided in the central chamber to impart rigidity to the structure. This profile is provided with an anti-corrosion coating. Additionally, the chambers have stiffening ribs. The purpose of the reinforcing profile is also that it is used to fix imposts.

Which profile of plastic windows is better?

When choosing an acceptable profile option for plastic windows, you should study what manufacturers offer. Let's look at several types that are popular:

KVE profile

Manufacturers: Germany and Russia. Available in three versions:

• Expert - price and quality correspond to each other;
• Select is something in between;
• Standard - fully complies with European requirements.

This type of profile for a plastic window has its advantages:

• it is durable;
• it is easy to care for;
• sound and thermal insulation characteristics tall;
• safe for people;
• withstands a wide range of temperatures;
• compatible with different systems.

As a minus, it can be noted that it may not harmonize with every interior, since the color is not snow white. And here are the characteristics in numbers for KBE Standard and KBE Expert to determine which one best profile for plastic windows:

KBE Standard KBE Expert

• installation width - 5.8 cm; 70;
• glass unit thickness - 3.4 cm; 42;
• cameras - 3; 5;
• light opening - 6.4 mm; 0.78.

Profile Deceuninck

Produced in Belgium by the Deceuninck concern. Systems:

• Favorite. More modern, more cameras. The cost is appropriate;
• Bautek - lower reliability. Based on the price, we can say that this is economy class.

• high heat conductivity;
• durable;
• safe;
• protects well from noise;
• satisfactory appearance;
• relatively low price.

Bautek is not a universal system. Not suitable for everyone.

REHAU profile

Produced by the German company REHAU. Produces profiles in seven modifications.

Positive sides:

• durable, long service life;
• resistant to very low temperatures;
• functional;
• environmentally friendly;
• heat and sound insulation are excellent;
• easy to care for;
• excellent combination with other systems.

The size of the sash is somewhat smaller, since the reinforcement chamber is relatively small in size.

Veka Profile

Country of origin: Germany. Basic profile systems:

• Softline;
• Euroline.

They differ in the size of the light spaces. For VEKA Euroline it is larger: 0.6 cm for a non-opening window and 1 cm for an opening one.

• Distinctive feature: the profile can have a width of 9.0 cm;
• strength characteristics, heat and sound insulation, temperature - high;
• are losing their popularity due to a fairly large percentage of lead oxide, which is why they cannot be called completely environmentally friendly.

You now know what profiles there are for plastic windows, but when making your choice, also read other information.

What to look for, what to ask about

The best profile for plastic windows will not guarantee the quality of the window if you do not take into account the following:

• prevailing temperature regime;
• where the window will be installed: in the office, at home, in a production facility.

Find out immediately what material is the basis of the profile plastic construction. If it's not galvanized steel, don't buy it. Otherwise, after some time you will have to deal with rust protruding in the holes through which moisture is drained. Besides this, the following criteria are also important:

• how many air chambers are there in the window;
• width of the glass unit;
• insulation contours - how many there are;
• quality of sound and thermal insulation.

Classes of double-glazed window profiles

Depending on the thickness of the outer wall, they are officially divided into 2 classes:

• A - high quality, the wall is thick;
• B - has lower characteristics.

To the air chambers

Number of air chambers in different designs The profiles of plastic windows are different. When choosing an acceptable option for your home, you need to know:

• the number of cameras in a double-glazed window does not necessarily correspond to their number in the profile;
• the more chambers in the profile, the greater the strength, heat and sound insulation. The cost, by the way, is also directly proportional to this indicator;
• most suitable option: a double-glazed window consisting of 2 chambers, inserted into a three-chamber profile.

Double-glazed window

The camera in a double-glazed window is what is located between the glasses. Double-glazed windows are:

• consisting of 2 glasses - single-chamber;
• from 3, 4 and so on - two, three, four chamber;
• are selected depending on the prevailing temperature conditions in the area where you live;
• The insulating properties of a double-glazed window are also affected by the thickness of the glass.

Glass can be:

• energy saving;
• sun protection;
• laminated;
• shockproof.

Interesting: to find out if they slipped you a single-chamber double-glazed window instead of a double-chamber one, use a lit match: bring it closer to the glass and count the images. As many images as there are cameras.

Home comfort and fittings

A window in a house will not be good without high-quality fittings, which means it will not provide sufficient comfort in the house. The list of accessories includes the following mechanisms:

• devices for transoms;
• locks;
• loops;
• rotary handles;
• tilt and turn mechanism;
• trunnions and more.

Window fittings must match general style rooms, so she is released different colors. And most importantly: do not skimp on accessories, otherwise even the most quality profile for plastic windows will not live up to your hopes.
