Plastic windows have long ceased to be a luxury item and have become a convenient and affordable option to replace traditional wooden frames. And naturally, every person wants to put himself in the house with the best plastic windows. However, the market offer of PVC window profiles is very large, and it can sometimes be quite difficult to choose the right option. Expensive and cheap, imported and domestic, three-chamber and five-chamber ... What should the buyer do? Carefully delve into the technical details of the production of window profiles? Not at all. It is enough to have some idea of how the profiles of plastic windows differ from each other.
Definition
Profile- the basis of the future window, we can say that this is its skeleton. The durability of the structure depends on it. And when the question arises, what is the difference between PVC windows, then most often it is the profile that is meant. The main difference between window profiles is the number of cameras and their design. According to GOST 30673-99, there must be at least two cameras in PVC windows. Usually produce three-chamber profiles.
Window profile chambers are air cushions located along the perimeter of the frame and provide a high degree of heat and sound insulation. What are the fundamental differences between three-chamber and five-chamber profiles?
Comparison
The five-chamber profile is much thicker, therefore, when installing such plastic windows, the likelihood of condensation and freezing of the structure is significantly reduced. In terms of rigidity, five-chamber plastic profiles are also superior to three-chamber ones. The greater the rigidity of the profile, the less likely it is that the geometry of the structure will change, as a result of which the window will let in cold, heat, and dust. Naturally, a five-chamber profile is more expensive than a three-chamber one.
3 and 5 chamber profiles
Also, the profiles of plastic windows may differ in the quality of the polyvinyl chloride used in their production. It is difficult to determine the quality of plastic when buying, all its shortcomings will come to light only during operation. Poor-quality plastic quickly wears out - scratches appear on it, the shine disappears and the product loses its attractiveness. To prevent this from happening, you should buy profiles made by companies with a good reputation.
To increase the strength and reliability, as well as for resistance to external influences, the profiles of plastic windows are reinforced. To do this, a metal profile made of galvanized steel or aluminum is laid inside the profile frame. Another important difference between plastic window profiles is their design and surface coloring. As a rule, these properties are determined by the method of the production process.

- The quality of the polyvinyl chloride used for their production;
- Reinforcement technology and materials used for this;
- The number of air chambers;
- Appearance;
- Mounting width of the profile.
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:
- Uniformity.
- Thickness.
- number of air chambers.
- 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 used 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 often order plastic window and door systems, office partitions and entrance groups from manufacturers.
For the consumer, the advantages of a PVC window over windows with wooden frames became obvious:
- in houses with plastic windows it became quieter and warmer;
- there was no need to insulate and paint a wooden frame every year;
- 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 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, stationery, 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 linear 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
- PVC profiles differ in scope: window, balcony, door and facade.
For each of the options, the corresponding profile designs have been developed.
- 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.
- 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.
- 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.
- 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 insulating glass unit to 25 mm.
- 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, with a rolled thickness and configuration that meets the system requirements.
- 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
- First, decide on the purpose of the future product.
- Study the climate in the area where windows or doors will be used.
- Create an order budget.
- 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.

Home / Windows and doors / New products / Narrow profile VEKA EUROLINE
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 frame made of reinforcing steel 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 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.
Currently, a wide range of different products is presented on the market of PVC-based windows. In order to attract the buyer of the company, manufacturers are developing new types of double-glazed windows, and also use different types of profiles from which plastic windows are made.
In this regard, the consumer has reasonable questions: what profile for windows to choose and what will serve as the criteria for his choice?
When choosing a profile used in the manufacture of plastic windows, it is necessary to be guided by the following criteria that determine the purpose of the window and its operating conditions, these are:
- The ability to provide the required level of heat and sound insulation of the room where it is planned to install a window of this design.
- The quality of the material used.
- Profile class.
- Possibility of installation of double-glazed windows of various design.
- Geometric dimensions of the profile (width and height).
- The presence of reinforcement.
- Possibility to install additional elements.
- Terms of use and care.
- Manufacturer's brand and its reliability.
- Price.
In practice, a PVC profile is used, which has a different number of chambers in its design, which ensure the ability of this structural element to retain heat inside the room and maintain the required level of sound insulation.
Structurally, this is expressed in the division of the internal space into several air chambers by means of partitions. There can be from three to eight such chambers (air cavities), of which the most popular among household consumers are three and five chambers.
By class, PVC profiles are classified as:
- Class "A" - wall thickness from 3.0 mm.
- Class "B" - wall thickness from 2.5 to 3.0 mm.
- Class "C" - wall thickness is not standardized.
Window profile materials
In the manufacture of windows, various types of profiles can be used, both in terms of its design and the material from which it is made.
It could be:
- Wood.
It is a natural and environmentally friendly material that has always been widely used in the manufacture of windows.
Currently, due to the emergence of new technologies and the high cost of natural raw materials, it is used less widely.
Wood species such as: teak, larch, oak, Canadian hemlock and teak wood are used in the manufacture of windows for individual orders and in the construction of premium class homes.
Coniferous trees are used in the manufacture of cheaper structures, but, nevertheless, they are still more expensive than products made from various types of plastics and some types of composites.
- Aluminum.
Pure aluminum is not a very successful material in terms of its use for the manufacture of window blocks. The reason for this is its high thermal conductivity and low elasticity.
In this regard, aluminum crane is rarely used in its pure form for these structural elements, but in combination with polyvinyl chloride materials it is an excellent component of such products.
- fiber composites.
Fiber composites are glass-reinforced plastics made on the basis of a reinforced profile and a fiberglass composite.
This material has good thermal insulation properties and strength indicators exceeding those of wood and metal, respectively.
The disadvantage that determines its rather narrow distribution is that under the influence of the external environment (precipitation, sunlight, etc.), this material delaminates.
When using a composite made on the basis of carbon fiber, this disadvantage is absent, but in this case the product is very expensive.
- Metal-plastic.
The use of aluminum, which serves as a frame in the manufacture of window profiles and plastic, made it possible to create a wonderful tandem of materials, which made it possible to combine their advantages and create a durable product with good thermal insulation properties.
It is metal-plastic profiles that are currently widely used in the manufacture of window blocks of various designs.
Hardware selection
The choice of fittings is an important point in the manufacture and equipment of the window, no matter how strange it may seem at first glance. In order to make the right choice, you need:
- Familiarize yourself with the types and purpose of fittings.
- Choose the most reliable manufacturer that produces quality products (based on user reviews).
- Decide on the needs of various types of fittings and their technical characteristics.
- Determine the ratio of price - service life of products.
The complete set and type of fittings for each particular window is individual, which is determined by its design and the method of opening the sashes (right or left, sliding or hinged type, blind or tilt-and-turn design, etc.).
The standard package of a window made of PVC profile includes the following elements, such as:
- Window hinges (lower and upper).
- Compensator.
- Protective mechanism (fuse) against slamming.
- Window sash lifters.
- Fasteners.
- Brackets.
- Tilt and turn mechanism.
In addition to the above products, the kit may include window sash rotation limiters, slotted ventilators, mosquito nets and locks that ensure the window is closed from the inside.
In the manufacture of fittings, various metals and their alloys are used, which characterizes their strength and reliability. From the outside, the fittings are covered with paint and varnish anti-corrosion materials.
The selection criteria for fittings are:
- Wear resistance.
- Resistance to external influences.
- Existence of a warranty period of operation and the certificate of conformity.
- Appearance (aesthetics) and usability.
Choosing a manufacturer of plastic windows
When the user is faced with a question related to the choice of plastic windows, in addition to the technical components that determine the characteristics of the window (the type of profile and the material from which it is made, the type of double-glazed window, the presence and quality of seals and accessories), there is also an organizational component - windows of which manufacturer to choose.
A large number of large and small companies of various forms of ownership operate on the domestic market for such products. However, the main manufacturers of metal-plastic profiles are only a few companies whose products have their own advantages and disadvantages, below are the most popular of them.

What profiles are most often chosen?
The type of selected profile depends on the purpose of the window and its operating conditions. In addition to this, an important factor influencing the choice is the service life and cost of the product.
When choosing, there are always personal preferences for a particular brand, as well as the presence of representative offices of the manufacturer in the region where the potential buyer lives. In the regions of our country, the products of various companies are popular, which is characterized by the presence of this type of production and competition between manufacturers.
For installation in residential buildings, 3- and 5-chamber metal-plastic profiles with a width of 58.0 and 70.0 mm, respectively, are in greatest demand. For the northern regions, 6 and 8-chamber profiles with a width of 90.0 mm are recommended.
It is not recommended to install plastic windows in residential buildings made from a profile intended for industrial buildings and objects, which must be marked on its surface (OBJECT, object, engine, Tender, etc.).
In addition to the fact that when choosing a window, you need to be careful and scrupulously familiarize yourself with the type and design of the profile, double-glazed windows and fittings, you need to take care of the quality installation of the purchased product. An incorrectly performed installation can cross out all the advantages of a window made of a metal-plastic profile.
