What is the difference between window profiles. How to choose a window profile? Decorative possibilities of profiles

The formation of polyvinyl chloride windows into a full-fledged segment has long been completed in the domestic market. Technological and functional frames have confidently replaced wooden counterparts, providing the consumer with reliable and ergonomic glazing. However, plastic profiles for PVC windows also cause ambiguous opinions from users, due to the variety of models and quality parameters of these products. Often the manufacturer's brand becomes a decisive selection criterion - certified windows are more likely to be endowed with the qualities and characteristics declared by the company. It remains only to figure out which brand guarantees the best profile properties.

What is a PVC profile?

Metallo plastic profile- this is a frame that can include up to eight cameras, but models with two or three compartments are more common. Actually, they depend on their parameters in general. It is logical that options for a larger area are weaker in insulating and soundproofing functions than plastic window profiles. small size. In order to increase thermal insulation, manufacturers use polyurethane foam, which fills the space of the chambers. A fiberglass coating is also common. In the list of the main distinguishing features of the profiles, the installation width also appears. The rigidity of the structure and, consequently, the reliability of the valves depend on these indicators.

Foreign manufacturers of profiles

For the most part, imported PVC windows are represented on the market by German products. The technologies of European companies have gone far ahead and today dominate this niche. The list of companies numbers dozens, and the leading positions in terms of quality and sales are occupied by the brands KBE, Rehau, Veka, Trocal, Deceuninck, etc. It is noteworthy that the windows of most German companies are manufactured in Russia under special licenses. Accordingly, many plastic profiles for PVC windows, whose names are of German origin, are produced in our country. Domestic manufacturers of brands such as Rehau and KBE strive to ensure proper quality by completely recreating the original

Russian profile manufacturers

Despite the wide representation of foreign window products, they are improving and Russian technologies manufacturing. One of the oldest domestic manufacturers metal-plastic profiles is Proplex. Having initially mastered Austrian technologies, the company strives to offer a wide range of glazing products.

The formation of the Montblanc brand was not without the help of Austrian specialists. At the moment, plastic profiles for windows with maximum width 120 cm is a system including five cameras.

The Novotex company, which has production facilities in the Moscow region, can perhaps be unconditionally called Russian. Engineers and technologists are constantly working to improve plastic structures, focusing on local climatic conditions. It is the latter factor, combined with a low price, that allows the Novotex brand to maintain competition.

Class A profiles

Although the quality of profiles is determined by general criteria, there is a division into classes, according to which it is unjustified to compare premium models and representatives of budget series. The former obviously win in terms of performance and durability, while the price becomes the advantage of the latter.

So, luxury plastic window profiles are positioned on the market as A-class. Such systems are distinguished by wall thickness (3 mm), reliable connections in the corners, as well as protection from external influences. Technical features A-class profiles are not felt during use, which, however, indicates the reliability of the structures. It is very problematic to dismantle them without a special tool, an optimal microclimate is created in the room, and aesthetic beauty with the possibility of tinting frames makes premium systems the best choice. Representatives of the A-class include profiles KBE, Rehau, Veka, etc.

Class B profiles

It is not necessary to count on impeccable technical and physical parameters in the windows of this group, but due to the relatively low cost, this product also deserves attention.

The thickness of the outer walls in B-class constructions is 2.5 mm. For this reason, plastic profiles for class B PVC windows are less resistant to physical impact. There is also an opinion about the unsatisfactory environmental performance of the profiles of this group, but this is not true. The absence of toxicity is a general condition for the certification of plastic structures.

Category C profiles

In general, modern C-class profiles fully meet the needs of the consumer both in terms of sound and heat insulation, and in decorative properties. Another thing is that premium competitors have raised the level of technical qualities quite high.

Category C representatives include profiles of such brands as Vektor, LG Hausys, AGF, as well as almost all domestic products, including Novotex. As a rule, they are used in providing non-residential premises, but there are also lines focused on installation in apartments and private houses.

Top Profile Ranking

Against the background of the development of technological methods for manufacturing profiles and fierce competition, it is not easy to identify The rating is formed on the basis of a combination of qualities and the introduction of fundamentally new properties. In this regard, the arrangement of leaders can be represented as follows:

This brand has earned the championship thanks to maintaining an unsurpassed level of the main qualities of window profiles. Among them are 50-year durability, increased heat and noise insulation performance, as well as environmental friendliness due to the addition of zinc and calcium compounds to the PVC formulation.

Being a serious competitor to KBE, the Veka brand takes the second place. The list of its advantages includes the manufacturing technology of "light" profiles, which at the same time ensure the preservation of heat and acoustic comfort.

3.Rehau

The Rehau company is rightfully included in the top three. The quality of the profiles of this manufacturer is achieved by adding lead compounds. As a result, the structures acquire high strength and stability in operation.

The following positions can be occupied by many plastic profiles for PVC windows. Which one is better among them should be determined by the same parameters. The Salamander and Deceuninck systems should be added to the top three. Although plastic profiles for windows of these brands are not so popular, their physical and technical qualities maintain a high level. They are also distinguished by ergonomics and well-thought-out configuration that facilitates installation and further use window systems.

Currently, in the Russian market of window products, despite the ever-increasing number of sales of wooden and aluminum structures, leadership is retained behind plastic windows. This is facilitated by the many advantages that PVC products. The main ones, of course, are excellent heat and noise insulation, long service life, the possibility of using additional accessories that increase the functionality of the window (mosquito net, thermometer, etc.), as well as a great appearance, coupled with an affordable price.

As you know, the basis plastic windows is a profile. In the entire light-transmitting structure, it accounts for approximately 10% of the entire area of ​​the product. The remaining 90% is occupied by double-glazed windows.

It's no secret that all PVC profiles included in the sale of windows are the same. In order to choose the best option that would fully meet the requirements for appearance, the level of sound and heat insulation, as well as the price, the buyer needs to have an idea about each element of the window, be able to freely operate with technical terms associated with each of its components.

In this article, we will consider in detail the main points that you should pay attention to when choosing a window profile, describe its design, and explain the meanings of the main technical terms.

How many cameras should a plastic window have.

The image is clickable.

When considering the characteristics of an interesting model of light-transmitting PVC construction, special attention should be paid to three points:

• profile;

The most significant characteristic of a profile is its intimacy, that is, how many chambers it consists of. Their number directly determines how well the plastic profile retains heat.

Profile with three cameras. For residents of regions where cool weather conditions prevail most of the time of the year, the most preferred option is a three-chamber window profile. Three chambers reliably protect the structure from blowing, which means that they perfectly retain heat in the room. In addition to this, a metal frame is built into them, designed to reinforce the plastic sidewalls. The three-chamber profile of a plastic window, as a rule, has a width of 5.8 cm.

Profile with four or five cameras. Products, which include four, are either intended primarily for operation in areas of the country where the summer season is not long, but temperature conditions obviously leaves a lot to be desired. The protection provided by a profile with such an increased number of chambers copes with even the lowest temperatures (30 C and below). Therefore, inside a room glazed with windows with a multi-chamber profile, it will be warm and cozy in any weather. It should be noted that the use of such windows in warm regions of the country is not justified due to: mild weather conditions; prices, which significantly exceeds the cost of their three-chamber "brothers".

Single chamber and double chamber profiles. They are mainly used for glazing apartments and private houses located in the southern part of Russia. A design flaw that prevents them from low temperatures to cope with heat retention is more than offset by their price - it is significantly lower than the cost of plastic window models, the profile of which includes large quantity cameras.

Structural elements of a plastic profile. Clicking on the mouse enlarges the image.

As a result. If you need maximum protection from the cold, opt for plastic window models with 4 or 5 chamber profiles. If there is no need for maximum heat saving in a glazed room, for example, in the southern regions of the country, where hot weather prevails, one- or two-chamber PVC structures should be chosen.

For the majority of buyers best solution for the home will be the acquisition of three-chamber systems.

Criteria for selecting a profile, depending on its thickness.

Sectional profile. Click to enlarge.

An important characteristic of the PVC profile is its thickness. It depends, first of all, on the number of chambers and indirectly indicates the ability of the window to retain heat: the wider the profile the warmer it is usually.

When choosing the optimal width of a plastic window profile, it must be taken into account that there are only a small number of options, of which the following should be highlighted:

58 mm. A profile with a width of 5.8 cm is the most popular in the Russian market of window structures. Against the background of the rest, more “fat brothers”, it stands out for a small price with rather tolerable characteristics. As they say - cheap and cheerful. However, if the buyer pursues the goal of glazing a window opening without claiming a super result, then plastic window models with a 58 mm profile will fully satisfy his desire.

70 mm. The profile width of 7.0 cm allows the product to be placed in it from 3 to 5 cameras. This thickness is more than enough to provide the glazed room with the proper level of heat and sound insulation.

90 mm. The widest profile option for PVC windows, which best of all copes with the issue of heat retention in the apartment. Accommodates up to 6 cameras. The main disadvantage of such a 9.0 cm solution is its price, which is significantly higher than other similar products with a smaller thickness.

There are also designs whose profile width is quite impressive 110-130 mm! Such windows are also called "Danish" or "Dutch". They are, so to speak, designed for an amateur.

Cross-sectional glass.

A double-glazed window, as mentioned above, occupies about 90% of the area of ​​\u200b\u200bthe entire window. To date, there are three types of double-glazed windows, differing in the number of glasses installed in them:

• Single glass option. Not suitable for installation in a residential area due to the lack of characteristics of such a double-glazed window. The main flaws in the design of a single-glazed window are poor heat retention, as well as the lack of protection against. With the onset of the cold season, such minuses can contribute to the cooling of the room, as well as the formation of an impressive layer of ice on the glass.
• double glass construction. Represents the most optimal solution for installation in an apartment, or a private house due to the good price-performance ratio. The so-called is practically excluded, and heat in a glazed room is retained much better than when using a double-glazed window, which contains only one glass.
• Three pane solution. With a triple-glazed window installed, it is possible to achieve not only the greatest savings in heat, but also the maximum security of the apartment from all kinds of noise penetrating its territory from the street. There are only two drawbacks to triple glazing - this is high price And .

From the above information, it follows that for most buyers the best option there will be a purchase of double-glazed windows, which will include three glasses. When there is a shortage Money you can opt for a double-glazed window, which has the best price / quality ratio.

Profile selection depending on the manufacturer and class.

When choosing a suitable window profile, in addition to its characteristics, its brand and class should be taken into account. Regarding the manufacturers of this type of product, it can be noted that today in the domestic window market you can find a fairly large number of brands that produce various models plastic windows, differing in constituent elements and, accordingly, characteristics.

Important! This issue was most fully covered in our previous materials, entitled "" and "".

Now a few words about the choice of profile class. There are two classes of such products:

Profile class A can be applied in residential buildings and geometrically complex facade structures. It has a long service life, has a wall thickness of at least 3 mm.

Class A profile. Click to enlarge.

Due to design features class B profile is usually referred to as a budget decision. The main factor influencing the price is the presence of a thin wall in the product. It is precisely because of the savings on the thickness of the material used for the chamber wall that PVC profile manufacturers class B were able to keep the prices of their products as low as possible. Price at a price, however, the buyer should remember that such a marketing move cannot but affect the duration of operation of a plastic window equipped with such a profile - the service life of the system will be significantly less.

Summing up a certain result of all the above, I would like to draw attention to a completely obvious fact: all elements of a plastic window are interconnected. Making a choice in favor of a warm double-glazed window, you should also take care of buying a warm window profile. Otherwise, the design, due to a significant difference specifications, may be unbalanced.

Plastic windows firmly occupy the leading deal. They differ in the highest level of heat and noise insulation, besides, 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 particular window profile guarantees the strength and durability of the entire system. In the note, we will compare the profiles of plastic windows that are different 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, however, some companies create a product with a width of 127 mm.

Its internal fraction is hollow, but 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-preserving characteristics. Another feature of the profile system is the width of the filling, which describes which type of double-glazed windows is allowed to be defined in the profile. They visit one- or two-chamber type, the width of the glass in a conventional double-glazed window is 4 mm (M1 brand).

Any cavity owns a close appointment:

• for the withdrawal of water;
• fastening accessories;
• gives an answer for strength, etc.

Profile paint has the ability to be diverse, the colors are applied in several ways:

• co-extrusion method - multilayer films create some obstacle that allows the product to endure dynamic overloads in the absence of defects;

• lamination - with imitation of the structure, for example, marbled or wood;
• monochromatic coloring.

PVC profile properties for plastic windows

Material

• This work is made from a variation of plastic - snow-white polyvinyl chloride.
• The material used is characterized by the highest chemical resistance to 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 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 completely any elementary or difficult configuration to the window, allowing to translate into reality, including the most extraordinary idea of ​​artists and architects.

Design

The internal fraction of the plastic case of the profile is divided by longitudinal barriers, in their own order they form cavities (weightless chambers). The small number of chambers in the profile is 3, the largest is 8. The number of chambers describes the degree of thermal insulation and sound absorption of the window, rather than lighter cavities, the greater these characteristics. It should be noted right off the bat that 3- and 5-chamber profiles are used by reputation.

Reinforcement

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

• L-shaped reinforcement discharge - an iron insert is installed along 2 walls;
• U-shaped discharge of reinforcement, in which place the alloy increases 3 walls;
• Hidden discharge of reinforcement - 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 profile wall thickness describes its accessory to a specific class:

• Class A - the thickness of the profile walls must be no less than 3 mm;
• Class B - profile, in which place 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 profile.

Comparison of plastic window profile manufacturers

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

• Germany - REHAU, VEKA, KBE, SALAMANDER, SCHUCO, KOMMERLING;
• Slovakia - INTERNOVA;
• Korea - LG CHEM;
• Belgium - DECEUNINCK;
• Russian Federation - MONTBLANC and PROPLEX.

• Window profile systems are presented in widths from 60 to 82 mm, the number of chambers - from 3 to 8.
• SCHUKO windows are easy to use and have good anti-burglary features.

MONTBLANC

On the territory of Russia there are 4 factories for the production of profiles.

• The Russian-Austrian company is armed with a production base, where research is carried out and new technologies are introduced.

• The Mont Blanc line covers 6 types of profiles, in which place the mounting width is from 58 mm to 120 mm, cameras - from 3 to 6.
• The durability of the profile system (60 years) is achieved with the support of deliberately created operational features for a formidable climate.

PROPLEX

• The plant surrounding in Podolsk produces a profile on German equipment in accordance with Austrian technologies.
• This product is manufactured in a width that has the ability to range from 58 mm to 127 mm, chambers from 3 to 6.
• The unique recipe allows you to make quality profile, which differs in impact strength and special whiteness.

It is also possible to compare the properties of plastic window profiles according to the tables below.

Profiles of the German company KBE

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

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

KBE Ideal - three-chamber profile

• Mounting width is 58 mm;
• width of external walls - 3 mm;
• the thickness of the double-glazed window has the ability to compose 34 mm;
• 3 chambers in the rim, sashes, impost (horizontal and vertical window bars);
• has the ability to be used in formidable conditions (-60 ° C);
• service life - 40 years;
• the production uses environmentally friendly used materials, does not contain lead.

Pros:

• with a profile width of 58 mm, it has 3 weightless chambers, their size and best condition guarantee resistance to heat transfer. These windows have the highest degree of density, which exceeds the existing GOST requests by 5 (!) Times, as if the complete absence of dust and drafts in the room guarantees;
• 2 sealed gaskets guarantee good sound insulation (46 dB each). The profile is specially equipped with horizontal lintels, thereby increasing the strength of the lock when the window is closed;
• In the KBE profile, stiffening ribs are supplied, which guarantee additional strength of the window system. Another increase in hardness is allowed by special stops, with the support of which a clear placement of the reinforcing iron insert is achieved.

KBE Specialist - five-chamber profile

• Good quality for use in severe conditions (-60°C);
• seal silhouettes fit class A;
• service life - 40 years;
• the production uses environmentally friendly used materials, does not cover lead in any way.

• five-chamber building allows you to achieve best sense thermal insulation, such a profile is able to retain heat by 20% more than conventional three-chamber systems. It is allowed to achieve excellent sound insulation by installing large double-glazed windows in a 70 mm profile;
• 13 mm profile groove allows you to define anti-burglary fittings, thereby ensuring the safety of the building;
• KBE profile Specialist owns additional horizontal jumpers, thanks to which the handles and hinges will become solidly fixed;
• with the device, the prefabricated seam is approximately 20% more spacious, allowing additional insulation to be performed in its own order.

Approximate price of windows made of KBE profile

An important reason when choosing this or that double-glazed window is its cost. Often it is considered decisive, however, German window profiles of the highest quality can never be cheap. Below is the approximate market price in Russia.

• On average, a single-chamber double-leaf window with volumes of 140x130 cm, in which 1 sash is deaf and the other is tilt-and-turn, will deserve:

1. from a profile of 58 mm from 7500 rubles,
2. from 70 mm - from 10,000 rubles.

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

1. from 58 mm profile 13,000 rubles;
2. 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 at least:

1. from profile 58 mm 10500 r.
2. from 70 mm from 12000 rubles

What to focus on when choosing a plastic profile with a double-glazed window

In order to find what profile thickness is needed, one must have basic knowledge about a double-glazed window, since up to 70% of heat loss occurs directly through it.

This colorless substance consists of 2 or more glasses, which are hermetically combined with the frame. A room (a light strip) appears between them, overflowing with rarefied air or an inert gas, such as argon or krypton. This family 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 an incomplete form it is classified - 4-16-4. Thus, its mounting width is the same 24 mm. The same 36 mm system comes out of a 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 go to the north side and there is a busy road nearby, then in this case the following option is suitable: a 5-chamber profile with a depth of 86 mm, replenished with a 32 mm double-glazed window with a protective noise-insulating film.

As soon as the balcony (gallery) is connected to the adjacent place, 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 ordinary balcony insulation, a 60 mm 3-chamber profile and a 30 mm single-chamber double-glazed window are suitable.

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

When installing plastic windows, the profile plays no less a role than the double-glazed window itself. The profile is the basis of all window construction. That is why it is worth approaching his choice very responsibly. Due to the large selection of profile systems, many are lost and do not know what to look for.

All profile products are divided into window and stand. Window profiles are the foundation for fastening the double-glazed window. That is why choose high-quality proven models.

A support profile for plastic windows is a plastic structure on which a window is attached. A window sill is attached to the base (base) profile. Also, this system has a site for attaching a drainage system. Often the height of the stand profile is 30 mm. Installed design hidden by a window and window sill.

The stand profile varies by price category. Budget options are made from recycled plastic. More expensive systems are made of white plastic.

In fact, the secondary material in this case does not affect anything except the price. Therefore, many professionals recommend taking budget options.

For plastic windows, two types of profiles are used: aluminum and PVC. PVC profile for plastic windows is much more economical and therefore more popular. They have good heat and sound insulation. At the same time, PVC construction is durable and beautiful. It allows you to perfectly fit the frame without gaps.

Plastic profile for windows is divided into three main price categories:

• Economy
• Classic.
• Premium.

Profile systems of the class "Economy" are the cheapest. In terms of quality, they are significantly inferior to the other two. Economy class structures can be installed in rooms that are not affected by external factors.

"Classic" differs from "Premium" to a greater extent, the price. Their quality is about the same. The only thing that distinguishes them is that premium installations often have completely useless "bells and whistles" that do not affect the service life of a metal-plastic window in any way.

During installation, many people have a question, which profile is better for plastic windows.

When choosing, first of all, pay attention to the main indicators:

1. Uniformity.
2. Thickness.
3. Number of air chambers.
4. Profile width.

The homogeneity of the product can be assessed "by eye". Good uniformity indicates a quality product. At the same time, the graininess of the profile system often indicates a fake design.

The thickness of the plastic profile has a significant impact on the thermal conductivity and sound insulation of the product. It must be at least 3 mm. The thickness of the base of the window directly depends on the number of air chambers.

Profile chambers are small voids filled with air. This structure of these structures contributes to good thermal insulation. Most often, firms produce profile systems with a number of chambers from 2 to 5. But there are seven-chamber designs. They are intended for the far north.

• Two-chamber profiles are mainly used for glazing balconies and loggias. They are considered the most budgetary.
• For glazing rooms, the most optimal in terms of quality and price are three and four-chamber products.
• Five-chamber structures are considered the warmest. But they have a significant drawback - a fairly high price.

Also, many experts argue that a large number of air chambers negatively affects the stability of structures to external factors - the sun, wind, rain. Such products may turn yellow and crack. In addition, the more chambers in the product, the softer it becomes. The design may not withstand the weight of the double-glazed window.

The profile width of plastic windows can vary from 60 mm to 90 mm. But the most optimal in terms of price and quality are 70 mm designs. In terms of quality, they are no worse than wide counterparts, but have a much lower price.

Market Review

All these requirements can be met by products from several companies. Therefore, many are wondering which company profile is better to choose for plastic windows.

In today's market, there are a huge number of manufacturers of metal-plastic structures. But experts advise choosing well-known trusted companies. The "promoted" companies seriously monitor the quality of their products. By choosing their products, you will definitely be sure that you have avoided a low-quality fake.

Choosing a Profile Manufacturing Company

Choose a trusted manufacturer

By quality and price, you can create a conditional rating of plastic profiles for windows.

The profiles of the KBE company are in the greatest demand in the modern market of metal-plastic structures. This German company appeared on the CIS market one of the first. It presents both budget options and more expensive ones. KBE products are environmentally friendly and are recommended for installation in kindergartens and medical institutions. KBE designs are considered one of the most durable. Their service life is 40-50 years.

Rehau profiles are very popular. This is a quality German company. In the designs of this manufacturer, high-quality environmentally friendly materials are used. Rehau also added a climate control function to their designs and a locking system that prevents entry into the house through the window. The only drawback of Rehau products is the small height of the sash.

The well-known company Veka has been losing ground a little lately. This is due to outdated design models in comparison with competitors. But the most important drawback of this manufacturer is the use of lead in the manufacture of structures. This radioactive element has a very negative effect on the human body, causing various diseases.

Lovers of interesting design solutions will appreciate Aluplast's designs. This manufacturer represents more than 40 decor variations. Aluplast is constantly developing various innovations in order to meet the requirements of the consumer more and more.

The disadvantage of these systems can be called their tightness. On the one hand, it contributes to good thermal insulation. On the other hand, such tightness contributes to the accumulation of vapors in the room and the room must be constantly ventilated.

Not very popular in the CIS countries and the first company that began to manufacture plastic windows - Trocal. The manufacturer's designs are quite strong, but they do not have any special distinguishing features from competitors.

Who else is striving to market today?

A novelty in the market of metal-plastic structures in the CIS countries is the Lg profile for plastic windows. Indeed, everyone is accustomed to seeing only the equipment of this company. In fact, in many countries, Lg products have already been evaluated as a good match between price and quality.

These window systems have good thermal insulation and long service life. The manufacturing company controls every stage of manufacturing the product, which is why they call their products “reliable”.

Whatever profile of plastic windows you choose, you should take care of the product seriously. Careful use of metal-plastic windows will prolong their service and will delight you for more than a dozen years.

To GREATLY simplify your profile selection be sure to watch the video below. At least for the first minute.

If you want to understand the criteria for choosing a PVC window, then one of the first indicators that experts recommend paying attention to is a PVC profile. Products are presented in various classes, each of which has its own characteristics. Having got acquainted with them, you will be able to choose the optimal type of window construction.

What should be a modern PVC window profile

To date, the main European quality standard for PVC window profiles is RAL-GZ 716/1.

It defines the following parameters for PVC products:

• class A: external walls should reach 2.8 mm in thickness, internal - 2.5 mm;
• class B: the thickness of the outer walls should not be less than 2.5 mm, the inner - 2 mm;
• class C: external and internal walls can have almost any wall thickness.

Naturally, it is better to give preference to the profiles of the first two classes, which are distinguished by excellent parameters.

But class C products, if used, are only for installation in technical premises or for temporary service.

What is the difference between class A profiles and class B profiles?

Although the wall thickness of the profiles of these two classes differs slightly, their consumer characteristics are very different. When tested, class A products are ahead of class B products in many ways. If we talk about compliance with DIN EN 12608, then the strength reduction for a profile with reduced wall thickness is 25%, and the pull-out resistance of self-tapping screws is also reduced by 20%, by 15% the ability to maintain its shape decreases.

Therefore, PVC windows, in the design of which a class B profile is used, do not last as long as products of the first category.

And yet, the class B profile has an important advantage - a more affordable cost.

What profile of a plastic window is better to choose? Selection tips and manufacturer rating

It is for this reason that such products are especially popular.

Benefits of each class

Almost all manufacturers of profiles for PVC windows, whose products are presented in the markets of post-Soviet countries, offer products of classes A and B. Only the manufacturer VEKA offers consumers products of only the highest category.

Thanks to various types profiles, their manufacturers try to satisfy the various wishes of their customers.

Therefore, each consumer can choose the most suitable product.

Class A profile will be the best option in the following cases:

• when the client is used to getting only the best and is not ready to compromise on quality;
• large money spendings are not a problem.

Class B profile may be preferred in the following cases:

• there is no need for a large margin of safety and thermal insulation indicators, which are inherent in products of the highest category.

  This choice is fully justified for the installation of plastic windows in non-residential premises, buildings with seasonal residence or at industrial facilities;

• The quality of a window structure is determined not only by the class of the profile.

  For example, to achieve an increase in strength, you can use reinforcement. And the installation of a double-glazed window with several chambers will help to increase the heat-saving parameters.

Russian legislation allows glazing of residential real estate using profiles of classes A and B.

Thanks to this, the consumer can make his choice, taking into account the purposes and purpose for which the plastic window is purchased. The financial side of the issue is also of no small importance. After weighing in detail all the reasons, you can choose the most suitable type of profile.

Which profile is better?

It all depends on the conditions of application of the profile and the quality of manufacture of the metal-plastic structures themselves. The only difference is that the quality of the profile itself can be influenced by the human factor.

The data is taken from the Internet.

Everything you need to know about choosing a PVC profile

For the manufacturer of window and door structures made of plastic important indicators when choosing a supplier of components is the quality of the materials needed in the production, appropriate equipment and tools that employees have to work with.

Most of the properties of the finished product are mainly influenced by PVC characteristics profile - the basis of the design of a window or door. Why is it the profile that determines the reliability and durability of a window?

What types of profiles currently exist? How to choose a PVC profile?

Width and thickness of the plastic window profile

The owner of an apartment with a window made of cracked for decades of operation wooden frame, which, due to impressive gaps, often had to be sealed with strips of paper for the winter in order to preserve heat, he dreamed of changing it to a white hermetic PVC structure.

In the late nineties and early 2000s in Russia, having a plastic window at home was considered very prestigious, and its installation was certainly included in the estimate of the then-favorite expression “European-style renovation”, which not everyone could afford. The presence of a plastic window then emphasized the status of a tenant of a house or an office owner.

Over the years, plastic windows have become cheaper, and therefore more accessible to the mass audience of buyers, and now plastic windows and doors are installed almost everywhere. Windows are gradually being replaced in secondary housing apartments, developers order plastic window and door systems, office partitions and entrance groups from manufacturers more often.

For the consumer, the advantages of a PVC window over windows with wooden frames became obvious:

1. in houses with plastic windows it became quieter and warmer;
2. there was no need to insulate and paint a wooden frame every year;
3. a plastic window is cheaper than a wooden counterpart.

If at the beginning of the formation of this market, the end consumer did not impose special requirements on the quality of a plastic window - the main thing was the fact that he had it at home, then over time he began to understand installer companies, the number of which grew in accordance with demand.

Since the window of one brand is still different from the window of another, the consumer now has to study the issue more deeply - the client himself asks the question of the quality of components for assembling the finished product. Therefore, at present, the developer and the window installation company have to meet the increased requirements of consumers and are more responsible in choosing manufacturers of PVC profiles, double-glazed windows and fittings.

About PVC window profile material

Polyvinyl chloride (PVC) is a white plastic, thermoplastic polymer of vinyl chloride.

Chemical formula: [-CH2-CHCl-]n. PVC is a product that is chemical compound carbon, hydrogen and chlorine, consisting of approximately 43% ethylene and 57% combined chlorine, which is obtained from rock and table salt.

We come across products from polyvinylchloride everywhere every day.

Corps household appliances, stationery, car parts, children's toys, disposable tableware, medical supplies, food packaging - all this is made of plastic. Material does not emit harmful substances, chemically stable and safe for humans. If we consider the environmental side of the issue, then PVC items that have served their time can be recycled many times and get a second life in new things.

Due to its versatility, barrier properties and environmental friendliness, PVC is also suitable for the manufacture of window profiles.

In its original form, PVC is a fine powder white color. But pure PVC is not enough for a window profile. Frost resistance and strength of the profile is provided by various additives. Each manufacturer has its own recipe for the technological composition of stabilizers and fillers.

PVC profile manufacturing process

PVC profile is made by extrusion. On the extruder, the polymer mixture is heated to the desired temperature, turning into a plastic liquid mass.

This mass is pressed through the forming tool, from where the profile blank comes out. Then it is pulled through the calibrators and cut into the desired segments.

Large manufacturers of PVC profiles carry out final control of geometric dimensions and weight running meter every hour.

A profile that has deviations higher than those allowed by the technological regulations is sent for recycling.
Since during the extrusion of window profiles there is a thorough homogeneous mixing of all the components of the recipe, a material can be obtained, the spectrum of properties of which varies in the widest range. At the same time, the use of additives does not change the fundamental properties of PVC as a thermoplastic, which are decisive in the design of window structures.

Types and characteristics of PVC profiles

1. PVC profiles differ in scope: window, balcony, door and facade.

   For each of the options, the corresponding profile designs have been developed.

2. Depending on the number of chambers, there are three-, four- and five-chamber profiles. These are the most popular options. Less common are two-chamber profiles (they are placed mainly in unheated rooms or as partitions). Profiles with six or more chambers are used in regions with severe frosty climates.

   The more chambers in a double-glazed window and profile, the higher thermal characteristics window blocks.

3. PVC profiles also differ from each other in such an indicator as width, which depends on the number and size of air chambers.

   The width of the PVC profile system can vary from 46 mm (for two-chamber profiles) to 130 mm. Wide frames protect the slopes from freezing, and in the case of using profiles with an intra-profile self-ventilation system, they normalize air exchange, remove excess moisture, move the window inside the room, closer to heat flows.

4. In addition to the width of the profile itself, there is such a parameter as the thickness of the outer (front) walls, which affects the strength characteristics of the PVC profile.
5. The depth of insulating glass is another indicator that affects the characteristics of the window.

   At the junction of the glass and the profile, a "cold bridge" is formed and heat is lost. In frosty weather, condensation may form around the perimeter of the window. In order to avoid the so-called "edge effect", profile manufacturers increase the depth of the double-glazed window to 25 mm.

6. The reinforcing element in the profile of the frame, sash and impost is the basis of their stability under the influence of wind and thermal loads on them. Each profiled part of the window must contain a metal reinforcing insert made of galvanized steel, the thickness of the rolled product and the configuration corresponding to the system requirements.
7. Important for the consumer are the aesthetic characteristics of the window. To satisfy this request of the customer of the window and door system, the PVC profile should be chosen based on its resistance to ultraviolet radiation, the possibility of choosing a color scheme.

   To prevent the window from yellowing over time, the manufacturer must add a sun protection component. Currently, in addition to color, you can choose the texture of the plastic profile, for example, wood. Or pick a color entrance group in accordance with the corporate style of the enterprise. Plastic windows can be not only rectangular shape. Arched openings can also be closed with PVC construction. Round, triangular, polygonal windows are available to fulfill the architect's intent.

How to choose PVC profile

1. First, decide on the purpose of the future product.
2. Study the climate in the area where windows or doors will be used.
3. Create an order budget.
4. Decide on the brand of the manufacturer and the supplier of the profile.

   Examine their assortment: whether their profiles will “cope” with the tasks set. Specify what equipment the production is equipped with, and from what raw materials the plant produces profiles. As a supplier, it is more reliable and profitable to choose an official representative of the plant, which has a set of preferential conditions and guarantees.

Narrow profile from VEKA

Today, plastic windows not only protect the room from cold, wind and noise, but also have an aesthetic value.

Plastic windows: everything you need to know

Many factors influence a person's mood, including a beautiful view from a modern window. in Vyborg, the climate does not indulge too much with sunny days, but every resident dreams of having as much sun as possible in his apartment on clear weather.

Thanks to the unique narrow profile VEKA EUROLINE from the Vyborg Window Factory company, the dream of Petersburgers becomes a reality.

The narrow profile of VEKA EUROLINE differs little from the standard profile of a similar model, but in terms of its parameters, the height of the profile installed on the sash, frame and impost is significantly lower. This information can be viewed in a table.

VEKA EUROLINE profiles in comparison

The use of a narrow profile in the installation of plastic windows does not in any way reduce their thermal insulation qualities, which is important for a simple user during operation.

According to the table, the mounting depth of the standard and narrow profiles have the same size, namely 58 mm. The number of cameras used in both variants is three. And you can get an answer to the question of the topic "NARROW PROFILE" by phone (go to contacts) or by writing us a letter.

Production of PVC windows

To become a window PVC profile must be properly processed and connected in the same structure. The process of manufacturing a window or door block from plastic profiles is the same and represents a transport chain of a large number of operations.

Only strict adherence to technology and standards (GOST) at the assembly ensures quality finished products. But all of that is great.

In order to obtain a clean, regular window and a geometric window, it is important to build a manufacturing process based on quality raw materials. In particular, high-quality PVC profiles, reliable equipment and energy-saving double-glazed windows.

Supply of PVC and its storage

The PVC profile is supplied from the manufacturer in the store with a large pallet.

Frame, wings, impost, glazing - all these elements of the window are brought by whips packed in six-meter pallets. To make a window out of them, they must be cut into blanks with the required length in accordance with specifications for cutting. Previously, they were stored in processor rooms equipped for this purpose.

PVC profile storage

In the future, the profile will focus on production line for windows where a new plastic window or PVC door is being produced.

He saw the profile

The profile is cut at an angle of 45 degrees and then welded into a frame or sheet.

The profile used for the production of windows has an internal space, which makes it more resistant to freezing, but at the same time weakens the power properties. In order for the window structure to be more stable and resistant to possible loads, a reinforcing steel frame is inserted into the central chamber of the profile.

This is also called a rebar profile.

Installation of the steel layer

Reinforcing (or reinforcing) PVC is a mandatory process for all types of windows that stand on a side greater than 400mm.

Otherwise the profile will not be stable even in case of linear expansion in case of temperature drop or mechanical action. However, for the manufacture of certain types of plastic windows, a reinforcing frame can be excluded.

For this type of products, there is a round, round and arched image. Profile enhancement

Production of window plastic windows

Arched windows and other PVC windows with a certain radius of curvature are made by bending in special tables.

Before bending the plastic whip, it must be heated to a temperature of 150 degrees Celsius. The bend becomes compatible, keeping the shape and certain geometry of the internal reinforcement.

Profile bindings in frames and skirts

When plastic profiles of a certain size are cast and reinforced with a reinforcing coating, they must form one window box: a frame or a sheet.

The most typical variant of connecting profiles is welding. The blocks are placed on the welding machine in the required sequence, their edges are heated to the melting point and pressed together.

profiles of the compound angle between welding power not only turn out to be worse than the strength of the corresponding profile, but also more (as in tests carried out in experimental laboratories).

However, the plastic-filled profile looks extremely unaesthetic and the next step needs to be cleaned up. For this purpose, use special cutting machines (grinding).

Discs and sawing exercises (cleaning) are configured to remove excess plastic and do not touch the underlying structure. After this step, the window frame and wing are prepared for the next procedure - the installation of fittings.

How to install accessories on PVC windows

Fittings - a set of metal elements (hinges and locking devices) that allow you to open and close the wing.

This is everything without which the window cannot be moved - and there is additional equipment.

Elements of this type are mounted on the frame and on the sheet.

Which profile is better for modern plastic windows?

To ensure that each element on the window frame matches the frame lock - all these processes are carried out in accordance with pre-marked sketches in accordance with the recommendations of the accessory manufacturer.

At this stage, the window is almost finished with the look and functionality, the only thing that is missing until it is fully prepared is the clear glass, which is installed in the next stage of the conveyor belt.

Glazing, installation of double glazed windows

Speaking about the glass filling of modern metal-plastic windows, it is worth mentioning the double-glazed window.

A double glazed block, unlike ordinary glass, is not only one sheet, but several sheets of glass fixed at a distance and sealed.

That's why the name is double glazing.

Today, glass blocks are made from different glasses, and the filling of the gap between the glasses can also be different. In the warmest (energy efficient) inert gas double glazing models, argon is induced in the cavity between the glass plates. It is heavier than air, so in winter it is better to prevent freezing and hot summer sun in summer.

We can talk about how the window turned out to be good at the end of fixing the last glazing.

The design (window or door block) should now be validated correctly. This is the task of the QC inspector.

The product and the sealed unit show no signs of damage, the protective film is peeling off, the functionality is in the order of the state - this window is suitable for shipping to the customer and complaints are unlikely.

How to distinguish a high-quality window from low quality. Video.

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 when recycling 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 first need to take care of this part of the window structure. 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:

1. 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.
2. 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 area of ​​\u200b\u200bthe wings and frame, so a 5-chamber profile would be the best option.

To make warm windows with any type of double-glazed windows, it is necessary to use profiles with 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 the purchase quality windows eliminates 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.
