By purchasing plastic windows, we rely on their long and trouble-free operation. I want to avoid unpleasant surprises in the form of skewed frames or cracks in them after a few months or years. A well-chosen profile for plastic windows is a guarantee of strength and durability of the entire structure. What types of profile exist, how to choose the right one and what to look for?

Types of profile for plastic windows

GOST 30673-99 specifies the profile classification according to its design features.

By class (by wall thickness)

According to the thickness of the outer and inner walls, the profiles are divided into the following classes:

• A - the thickness of the outer walls from 2.8 mm, internal - from 2.5. The best indicators of strength and thermal insulation among all types.
• B - outer walls from 2.5, inner - from 2.0. Compared to class A, they retain heat worse, are more prone to deformation.
• C - all profiles that do not fit the parameters of classes A and B. There are no strict requirements for them. For window frames in apartments, this type is undesirable.

In non-residential industrial premises, frames from the so-called object profile are often installed. It is thin, poorly retains heat, easily deformed and therefore not suitable for an apartment. It happens that unscrupulous companies offer cheap windows made of such material. The “objekt” marking on the protective film will help to recognize the fraud. On other grounds, it is problematic to determine a fake at first glance.

By width

The profile has different widths:

• 58 mm - the most common, most often placed in apartments and houses.
• 70 mm - profile width for windows in high-rise buildings or buildings located in cold climatic zones.
• 90 mm - premium class with the best sound insulation and insulation characteristics. Piece products, which are not in the assortment of most companies that install plastic windows.

By number of cameras

The number of air chambers in it depends on the thickness of the profile:

• The 58mm has a maximum of three cameras.
• In a product with a thickness of 70 mm, there can be from three to five.
• With a width of 90 mm, the norm is six chambers.

The more internal chambers, the higher the thermal insulation and noise reduction performance. But in reality, the difference between frames, for example, with a 3- or 4-chamber profile is negligible.

The corporate profile is homogeneous in structure and color. To verify its authenticity, look for the factory marking on the inside. In addition to the name of the company, there should be numbers indicating the shift number, date of manufacture and other data related to production.

A few words about double-glazed windows

An important aspect is the number of chambers between the glasses in a double-glazed window. Do not confuse them with profile cameras.

• For glazing unheated premises (balconies, summer terraces), single-chamber double-glazed windows are used.
• For living rooms, a double package is optimal - three glasses separated by two air chambers.
• In cold winters, three-chamber structures are used. They have the best indicators of thermal insulation, but they let in less sunlight, and they weigh more. It makes sense to install such windows in the northern regions.

Read about all the intricacies of choosing the elements of a plastic window - profile, double-glazed windows, seals, fittings.

In Russian climatic conditions, where there are significant temperature differences between summer and winter, only reinforced frames are used.

Structurally, the reinforcing profile is a contour made of galvanized stainless steel. There are two types of contours:

• Closed, or O-shaped.
• Open, U- or G-shaped.

There are several important points to note:

• Manufacturers sometimes refer to O-shaped reinforcement as "warm". However, this is not the case: the thermal conductivity of metal is higher than that of plastic. Therefore, the more it is in the frame, the worse it will retain heat.
• O-shaped reinforcement is called closed, but to compensate for the temperature change in the dimensions of the metal in the circuit, a technological gap is necessarily made.
• A closed-loop frame is stronger, while an open-loop frame is lighter and warmer.

According to GOST, the wall thickness of the reinforcing profile must be at least 1.2 mm for standard systems and at least 1.5 mm for non-ferrous and frost-resistant structures (painted plastic heats up more).

Connection profile

Designed for joining individual frames that make up a single glazing structure, which are mounted at a certain angle. It is needed if it is necessary to glaze a complex broken structure with large windows: a winter garden, a loggia or a partition.

Depending on the required location of the elements to be connected, there are types of connecting profile:

• With connection angle 0˚.
• With docking at a right angle - 90˚.
• With a variable angle of rotation, or simply rotary.
• Firms producing docking elements unify them with the products of well-known companies (KBE, Rehau, Veka), so it is not difficult to choose the right profile for the frames.

Additional (expansion) profile

It is used to increase the size of the window frame, when the thickness of its plastic part is not enough, taking into account the insulation or decoration of the walls or ceiling. Most often, such an element is used for glazing balconies and loggias.

Important! It is strongly not recommended to use an expansion profile only to fit the frame to the dimensions of the window opening. No matter how competently an additional element is selected and installed, in terms of thermal conductivity and strength, such a design will still yield to a monolithic frame.

Additional profiles are produced with a width of 2 to 10 cm. The grooves in them are arranged in such a way that parts can be combined to obtain the desired height: simply insert one into the other. For example, to expand the frame by 8 cm, two 4 cm thick extensions are used. The standard element length is 6 meters.

For an insulated balcony, an extension is selected that is identical in quality to the main frame, including with the same reinforcement. Without it, the window unit will not have the necessary rigidity.

Stand (installation) profile

A detail that is often overlooked when installing plastic windows. If a substitute profile is included in the scope of supply, it is usually already attached to the frame. Its functions:

• Protects the frame from damage during transport.
• Strengthens the structure and prevents it from freezing in the lower part, where the window block adjoins the wall.
• Provides reliable fastening of a window sill and ebb.

Base element dimensions:

• The standard length is 6 meters.
• Width - from 2 to 4 cm.
• Height - from 2 to 3 cm.

Starting profile for slopes of plastic windows

Needed for fastening to the base and docking them together. This is a kind of plastic bracket mounted at the attachment points.

The variety of their types is due to the methods of mounting panels. The types of the starting profile got their names from the Latin letters that their sections look like:

• I-variety. It can be installed in any position so that the long central shelf is perpendicular to the surface on which the slope is mounted. Plastic panels are attached to a short profile shelf.
• The F-variety has two short shelves and one long one. Serves not only for fixing slope panels, but also covers the junction. With it, there is no need for a decorative corner.

• L-profile is the most versatile and popular. It is installed perpendicular to the plane of the window, with a wide shelf to the wall. The narrow transverse part adjoins the window frame, and the strip parallel to the opening masks the junction of the frame and the slope.

• The U-variant is very similar to the previous one, but has two wide shelves, which allows the element to cover a wider seam.

These starting elements are attached to self-tapping screws or glue. With their help, it is easy to mount plastic slopes without the complicated procedure of leveling the window opening with plaster.

color profile

Many people do not like the usual white plastic windows precisely because of their similar design. However, there has long been a way out of this situation: colored plastic windows. Technologies allow you to get a profile of any color, but shades of brown are the most successful: this is how different types of wood are imitated.

Get products of the desired color in several ways:

• Bulk lamination - color is added at the manufacturing stage, and a protective film is applied to the surface of the element to protect it from sunlight. The cost of such a window is from 14 to 21 thousand rubles.

• Film lamination - the white profile is covered with a multilayer durable film that imitates expensive wood species. The film can also be applied to the ends of frames, as well as to fittings, such as hinges. It costs less than the previous option: from 9 to 17 thousand rubles. outside the window.

• Coloring with acrylic paints. The most budgetary way: from 7 to 18 thousand rubles.

• Application of colored plexiglass melt using an extruder. From 15 to 20 thousand rubles.

Manufacturers of profiles for PVC windows: rating

A variety of window profiles makes it difficult to choose. On the one hand, I want the quality assurance that well-known manufacturers give. On the other hand, it is undesirable to overpay for the popularity of the brand.

All brands, with the exception of Salamander, are manufactured in Russia according to Western standards and on imported equipment. Therefore, the quality of products of the same brand, produced at different factories, may differ slightly.

• Veka. A German company, profile systems are manufactured at factories in the Moscow region, Novosibirsk and Khabarovsk. There is an ISO 9001 certificate, the products have been awarded the German RAL quality mark. The buyer can choose from 6 types of profiles with 3, 4, 5 and 6 chambers with a width of 58–90 mm.

• Rehau. A company from Germany has been producing profiles in Russia since 2002 at a certified plant in Gzhel. The leader in the number of products produced per year, offers 7 models with 3, 5 and 6 chambers and an installation width of 60, 70 and 86 mm.

• KBE. German company with factories in Voskresensk and Khabarovsk. 7 modifications of profile systems, there are 3-, 4-, 5- and 6-chamber options, width - 58, 70, 88 and 127 mm. At the same level of quality, KBE frames will cost about a quarter less than Veka and Rehau products. For the best window assembly companies, the manufacturer issues a Certificate of Official Partner.

• MONTBLANC. The manufacturer is an international company with 4 factories in the CIS. Produces 7 models from 58 to 120 mm wide with 3, 4, 5 and 6 chambers.

• salamander. The entire profile is produced only in Germany, so it costs more than competitors with Russian factories. It has an attractive design, there are 3 types of profile systems with a width of 60 and 76 mm.

• Grain. Domestic manufacturer with a factory in Ufa. In the line - 6 types of profiles with a width of 58 and 70 mm with 3 and 5 chambers. The most famous models are Vector70 and Vector58.
• Exprof. A large Russian company that manufactures a profile adapted to the conditions of Siberia using German and Austrian equipment. It offers 9 types of profile systems: 2-chamber for balconies and 4-, 5- and 6-chamber systems with a width of 70, 101 and 118 mm. 4 types have a built-in ventilation system.
• Proplex. A Russian company with a full production cycle from profile manufacturing to final assembly. The structures were designed jointly with Austrian developers. The range includes 6 models with 3, 4 and 5 chambers with a width of 58–127 mm.
• Deceuninck. The Belgian concern with a factory in the Moscow region produces a profile of 5 types, 3-, 5- and 6-chamber 60–84 mm wide.
• Kaleva. Moscow profile manufacturer and window assembler rolled into one. Offers 2 classic models and 3 designer models with the same installation width of 70 mm and 4 to 6 chambers.
• wintech. The Turkish company, which makes profiles and accessories for them on German equipment, has a certificate of conformity. The line includes 6 models with a width of 50-80 mm and the number of chambers from 3 to 6.

When choosing, beware of fakes and buy only from trusted sellers. A high-quality profile is the key to the reliability of a plastic window.

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

The ability to notice the first signs of fakes is a guarantee not to become a profit for scammers.

They entered the construction industry very firmly. Very soon, the wooden execution of windows will be a curiosity that you will not see anywhere. And there are explanations for that.

Benefits of plastic

Firstly, plastic is a cheaper material than wood, secondly, it is convenient to use, and thirdly, it is very easy to make repairs in such windows.

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

Specifications of PVC window

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

Brands

A company with a well-known name cannot afford absolutely disgusting products. Most likely, these will be one-day firms.

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

REHAU windows

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

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

VEKA

Also a representative of German, loved all over the world. They produce a white and colored profile that is able to not lose color when exposed to sunlight for a long time.

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

KBE

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

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

Trocal

The company is one of the pioneers in the production of PVC profiles. Offer a huge range for decorative possibilities.

MOTNTBLANK, PROPLESS, BRUBEBOX

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

You can even choose a forum and ask questions of interest to the owners of such windows. The main advantage here can be called an affordable price.

When installing plastic windows, the profile plays no less a role than the double-glazed window itself. The profile is the basis of the entire window structure. 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. The installed structure is hidden by a window and a 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.

Fans 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 respects. 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 on the markets of the 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 of 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 cash costs 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 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 a manufacturer of plastic window and door structures, important indicators when choosing a supplier of components are the quality of 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 the characteristics of the PVC profile - the basis for 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 a wooden frame that had dried up over decades of operation, which, due to impressive cracks, often had to be sealed with strips of paper for the winter in order to preserve heat, 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 of having 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 a chemical compound of 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.

Cases of household appliances, office supplies, car parts, children's toys, disposable tableware, medical supplies, food packaging - all this is made of plastic. The material does not emit harmful substances, is 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 white powder. 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 the geometric dimensions and weight of a 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 the thermal characteristics of 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 design.

   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 choose the color of the entrance group in accordance with the corporate identity of the enterprise. Plastic windows can be not only rectangular in 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, a PVC profile must be properly processed and connected in one 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 the quality of the finished product. 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. In order to make a window out of them, they must be cut into blanks of the required length according to the cutting specifications. Previously, they were stored in processor rooms equipped for this purpose.

PVC profile storage

In the future, the profile will be oriented to the production line for windows, where a new plastic window or PVC door is 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 according to 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 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.
