Which profile of plastic windows is better. Which plastic window profile is better to choose? Selection tips and manufacturer ratings What is a window profile

Plastic windows firmly occupy the leading position. They differ in the highest level of heat and sound insulation, in addition, they give the choice of fittings, window opening method and profile colors. It is also possible to choose a double-glazed window with the required number of cameras. However, not many people think that specifically window profile guarantees the strength and durability of the entire system. In this note we will compare profiles that differ in features and manufacturers plastic windows.

General information about the profile of plastic windows

On average, the profile thickness of plastic windows varies from 58 mm to 86 mm, but some companies create a product with a width of 127 mm.

Its internal shot is hollow, but is divided 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-saving characteristics. Another feature of the profile system is the width of the filling, which describes what type of double-glazed windows can be defined in the profile. They come in one- or two-chamber types, the width of the glass in a regular double-glazed window is 4 mm (grade M1).

Any cavity has a similar purpose:

for draining water;
fastening accessories;
gives an answer for strength, etc.

Profile paint can be varied; colors are applied using several methods:

co-extrusion method - multilayer films create a certain barrier that allows the product to endure dynamic overloads without defects;

lamination - imitating the structure, for example, marble or wood;
monochromatic coloring.

Properties of PVC profiles for plastic windows

Material

This piece is made from a variation of plastic - snow-white polyvinyl chloride.
The material used is distinguished by its highest resistance to chemical action by 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 produce frames for double-glazed windows that are not only rectangular or square shape, however, also in the form of arches, triangles, circles and so on. Thus, giving any elementary or complex configuration to the window, allowing even the most extraordinary ideas of artists and architects to be realized.

Design

The internal grain of the plastic profile body is divided by longitudinal fences; in their own order, they form cavities (weightless chambers). The smallest number of chambers in the profile is 3, the largest is 8. The number of chambers describes the level of thermal insulation and sound absorption of the window; the lighter the cavities, the greater these characteristics. It should be immediately noted that 3- and 5-chamber profiles are used for their reputation.

Reinforcement

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

L-shaped reinforcement category - an iron insert is installed along two walls;
U-shaped reinforcement discharge, where the alloy increases 3 walls;
Hidden reinforcement discharge - 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 thickness of the profile walls describes its accessory to a specific class:

Class A - the thickness of the profile walls must be at least 3 mm;
Class B - profile in which 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 the profile.

Comparison of manufacturers of plastic window profiles

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

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

SCHUKO windows are easy to use and have good anti-burglary properties.

MONTBLANC

There are 4 manufacturing plants for the production of profiles located in the Russian Federation.

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 the installation width ranges from 58 mm to 120 mm, chambers - from 3 to 6.
The durability of the profile system (60 years) is achieved with the support of deliberately created operational features for severe climates.

PROPLEX

The plant located in Podolsk produces the profile on German equipment in accordance with Austrian technologies.
This product is manufactured in widths that can range from 58 mm to 127 mm, chambers from 3 to 6.
The unique recipe allows us to produce quality profile, characterized by impact strength and special whiteness.

You can also compare the properties of plastic window profiles using the tables presented below.

Profiles of the German company KBE

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

The KBE company manufactures and supplies 2 types of more required 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 glass unit can be 34 mm;
3 chambers in the rim, sashes, impost (horizontal and vertical window bars);
can be used in severe conditions (-60°C);
service life - 40 years;
The production uses environmentally friendly materials and does not contain lead.

Pros:

with a profile width of 58 mm, it has 3 weightless chambers, their size and excellent condition guarantee resistance to heat transfer. These windows have the highest level of density, which exceeds the existing GOST requirements by 5 (!) times, as if guaranteeing a complete absence of dust and drafts in the room;
2 hermetic sealing gaskets guarantee good sound insulation (46 dB each). The profile is especially equipped with horizontal jumpers, thereby increasing the strength of the lock when closing the window;
The KBE profile is equipped with stiffening ribs, which guarantee additional strength of the window system. The hardness can also be increased by special stops, with the support of which a clear placement of the reinforcing iron insert is achieved.

KVE Specialist - five-chamber profile

The installation width is the same 70 mm;
width of external walls - 3 mm;
the thickness of the glass unit is 42 mm;
5 chambers in the rim and sashes, 3 or 4 in the impost (horizontal and vertical window bars);
Benign for use in severe conditions (-60°C);
seal silhouettes are suitable for class A;
service life - 40 years;
During production, environmentally friendly materials are used and do not contain lead in any way.

A five-chamber building allows for the best possible thermal insulation; this profile can retain heat 20% more than conventional three-chamber systems. It is possible to achieve excellent sound insulation by installing large double-glazed windows in a 70 mm profile;
The 13 mm profile groove allows you to install anti-burglary fittings, thereby ensuring the safety of the building;
KVE profile The specialist has additional skills horizontal lintels, thanks to which the handles and hinges will become firmly fixed;
with the device, the prefabricated seam is approximately 20% more spacious, allowing for additional insulation in its own right.

Approximate price of windows from KBE profile

An important reason when choosing this or another double-glazed window is its cost. It is often considered decisive, but German window profiles of the highest quality cannot be inexpensive. Below is the approximate market price in Russia.

On average, a single-chamber double-hung window with a volume of 140x130 cm, in which 1 sash has a dull appearance and the other is tilt-and-turn, will deserve:

from a 58 mm profile from RUB 7,500,
from 70 mm - from 10,000 rub.

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

from 58 mm profile 13,000 rubles;
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 no less than:

from profile 58 mm 10500 rub.
from 70 mm from 12,000 rub.

What to focus your interest on when choosing a plastic profile with double-glazed windows

To find the required profile thickness, you must have basic knowledge about double-glazed windows, since up to 70% of heat losses occur specifically through it.

This colorless substance consists of 2 or more glasses, which are hermetically combined with the frame. Between them a room appears (a light strip), filled with rarefied air or an inert gas, such as argon or krypton. This type 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 its incomplete form it is classified - 4-16-4. Thus, its installation width is the same 24 mm. The system, the same 36 mm, comes out of a two-chamber double-glazed window, which consists of 3 glasses of 4 mm each and 2 layers of 10 mm each - 4-10-4-10-4.

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

If the windows face 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, supplemented with a 32 mm double-glazed window with a protective noise-insulating film.

When a balcony (gallery) is connected to an adjacent space 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 conventional insulation of a balcony, a 60 mm 3-chamber profile and a 30 mm single-chamber double-glazed window are suitable.

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

A window profile is a frame that holds a glass unit. Different types of window profiles differ in the material of manufacture and internal structure. Let us consider in detail the differences and advantages of profile structures, their quality, cost and performance characteristics.

What types of windows are there?

Modern window profiles for double-glazed windows are made of polyvinyl chloride (PVC), wood or metal (aluminum profile). Each of the above materials has its own advantages, which determine its popularity and cost.

Wooden window profile

Wooden frames represent the most expensive, prestigious design window opening. Natural wood requires long-term drying, thorough impregnation with an antiseptic and protection from moisture. Therefore, the cost of a wooden window is an order of magnitude higher than a plastic profile. If the wood is not dried enough or treated incorrectly, expensive windows can collapse within a year of their installation.

The look of natural wood creates a prestigious design and attractive aesthetics. With proper preparation, wood is quite durable and reliable. The best wood for making window profiles is oak, larch; alder and pine wood are more accessible.

Let's summarize the advantages of wooden profiles:

aesthetics and prestige;
natural environmentally friendly material;
good heat capacity.

Flaws:

Possibility of warping, swelling, cracking and other types of damage;
Expensive;
High professionalism of the master manufacturer is required.

An option for using wood for double glazed windows is wood-aluminum profile. In it, the wooden material is covered on the outside with metal plates. From the inside, on the living side, the frame shows natural wood; on the outside, the frame is protected from moisture by metal.

Aluminum profile

Aluminum window profiles are made with a small number of chambers (two or three). Metal itself is an insufficient heat insulator, because of this metal windows cold. They are mainly used for glazing large retail areas, airports, but also balconies and loggias. "Warm" metal windows are equipped with a thermal liner that increases heat capacity profile design. The cost of such windows is significantly higher than “cold” ones.

A metal window is characterized by the following advantages:

strength;
low flammability;
durability.

Flaws:

low heat capacity (for “cold” profiles);
high cost (applies to “warm” structures).

Two main types of aluminum alloy profiles are in demand in various buildings. “Cold” aluminum profile is used where an inexpensive frame is needed, good strength, without special requirements for heat retention. The “warm” expensive profile is installed in heated rooms for durable operation in cold winter conditions.

PVC profile

PVC profile is called a plastic window. Its characteristics:

high thermal insulation;
moisture resistance;
various designs (thanks to gluing laminated film).

Thermal insulation properties are ensured by the presence of hollow chambers inside. Due to the resistance of plastic to atmospheric precipitation, it does not absorb moisture, does not swell, does not rot or crack.

PVC has some disadvantages:

flammability (characteristic of most plastics);
The more cameras, the greater the weight of the structure, the higher the requirements for window installation.

Due to its affordable cost, PVC profiles have become the most popular material for the manufacture of double-glazed windows. Dozens of different manufacturers produce PVC. Their profiles differ in the number of chambers and the thickness of the plastic wall. Let's consider what characteristics are used to evaluate PVC profiles.

Characteristics of PVC window profile

Popular manufacturers of window profiles

REHAU is a German manufacturer and has its own production in Russia. It supplies the Russian market with six models of profiles: 3-6 chambers, the width of a standard double-glazed window is 32–40 mm; in wide double-glazed windows (86 mm), special glass is installed and fiber is used. The heat transfer resistance coefficient is from 0.64 to 1.05 (for fiberglass profiles). The manufacturer regulates that a coefficient of 0.95 corresponds to the heat capacity of a brick wall one meter thick.
KBE is a German manufacturer with two subsidiaries in Russia. Produces 8 profile models with different characteristics: 3-6 cameras, glass thickness from 32 to 52 mm. The heat transfer coefficient of the KBE profile is 0.7 – 1.04.
VEKA is a Russian-German manufacturer, VEKA Rus is a subsidiary of VEKA AG. It produces standard blocks and non-standard design structures for window openings and balconies in accordance with the European RAL standard. The main models produced: Softline (for double-glazed windows from 4 to 42 mm, five chambers, heat transfer resistance coefficient 0.75), Softline 82 (glazing unit width 24-52 mm, seven chambers, coefficient 1.0), Euroline (three chambers, double-glazed window 32 mm, coefficient 0.64), Proline (four chambers, 4-42 mm, coefficient 0.75), Swingline (6-42 mm, five chambers, coefficient 0.77), Alphaline (elite 6-chamber profile with high coefficient 1.04).
MONTBLANC is a German manufacturer that supplies four types of profiles from 3 to 6 chambers (eco, thermo, nord and grand) to Russia. The width of the double-glazed windows is 32, 42 and 52 mm. Heat transfer resistance ranges from 0.6 to 0.82 mm. Frame thickness from 60 to 80 mm. Six air chambers are laid in a width of 80 mm. High heat-saving functions make the profile popular in Russia.
SALAMANDER (also Germany) - produces profiles of 3, 5 and 6 chambers with frame thicknesses from 60 to 92 mm. Dimensions of mounted double-glazed windows: 32 mm, 48 and 60 mm. The widest Salamander BluEvolution profile has a heat transfer resistance of 1.0. The manufacturer regulates high burglary resistance of windows(thanks to a closed reinforcement system).
Schuco is a German manufacturer that produces 3-7 chamber PVC profiles for standard and energy-efficient construction. The maximum heat transfer resistance coefficient is 0.94. Double-glazed windows up to 36 mm thick. In wide frames with a thickness of 82 mm, it is possible to install anti-burglary fittings. Schuco also produces warm aluminum profiles with a number of chambers from 3 to 7, steel profiles for cold glazing.
TROCAL is a German manufacturer, the founder of the industry, which introduced the first plastic window to the construction market (in 1954). Has been producing window profiles for almost 60 years. The width of the double-glazed windows is from 30 to 58 mm. Four to five chamber profile, 70 and 88 mm installation width. The heat transfer coefficient is 0.82. Lead-free technology allows you to install the profile in child care institutions (kindergartens and schools).

And finally: accessories

Fittings are a set of metal parts that provide a movable connection of various elements in the overall structure of the window. The durability of the window product depends on the quality of the fittings.. It is important to know that famous brand manufacturers have cheap lines of lower quality fittings for Eastern European countries.

Types of window fittings:

Tilt and turn (for opening the window and tilting the transom).
The lock and handle are a multifunctional design that locks the frame in any position using an internal axis.
Parallel-sliding (for retractable sashes).
Tilt-and-slide.
Vertical sliding.

In addition to fittings, the design of double-glazed windows uses. They provide the necessary insulation from noise and cold.

The selection of a window profile, its main characteristics and fittings is carried out in accordance with the required thermal capacity of the window and the price level for its manufacture. The quality of the profile and fittings determines the appearance of the double-glazed window and its performance characteristics: thermal insulation, sound absorption, strength and durability.

I am glad to welcome my readers!

I've installed a lot of windows in my career, but most of the time the quality wasn't very good.

The fact is that the main thing in a plastic window is the profile, but at first glance, all windows look the same. This is why I often encounter clients choosing a low-quality profile.

What is the main thing about plastic windows? The basis of plastic windows is a profile. A good profile is the key to high-quality and reliable plastic windows.

How to choose a high-quality profile and what to look for when choosing? I want to help you find the answer to this question in this article.

We go outside or take a newspaper and what we see are windows KBE, REHAU, VEKA, SALAMAHDER, LG, PROPLEX, BRUSBOX and the like. What is behind all these names? - These are the names of window profile manufacturing companies and nothing more, and your windows will be manufactured by completely different companies, and we know very well what our manufacturers can make from the best raw materials.

And yet a little about profile manufacturers. When ordering windows, you will hear from the manager that the windows (for example, KBE, VEKA, REHAU, SALAMANDER) are German windows made in Germany - naturally the best and highest quality. What is true in these words and what is not? Of all those listed, only SALAMANDER is 100% produced abroad (that’s why it has a corresponding price), the rest have been produced in Russia for a long time.

And about the production of window profiles itself. Most profile manufacturing plants have built their factories in Russia. I visited the KBE and VEKA factories - excellent factories, imported equipment, foreign specialists, imported raw materials, so where the profile comes from doesn’t make much difference (I think the situation is similar at other factories of European manufacturers).

True, as always, there is a “BUT”. This is a “BUT” profile system produced specifically for Russia, i.e. they don’t use it abroad - it’s only for us at “our request.” The advantage of this system is that it is cheap, the disadvantage is that to reduce the cost, the profile walls are made thinner, and therefore the thermal resistance is lower and the strength is lower.

For the south this is quite acceptable, in middle lane— It’s doubtful, they might freeze in the north. Typically, this profile system is called an object profile and is used for glazing large objects - multi-storey residential buildings, industrial enterprises, etc. There are also Russian and Turkish systems, but since we are going to glaze our house, we will not consider these systems in detail.

I can write further which profile I personally prefer.

Which profile do you think is better? Which is better Rehau or Brusbox? Century or Proplex? KBE or LG? etc.

The most difficult and annoying question, to which it is almost impossible to give a reasoned answer, I can only express my personal opinion. I emphasize once again that this is my personal opinion, not advertising, and the conversation will only focus on the profile systems with which I worked.

A few words about SALAMANDER (not in competition) – a good profile. The main advantage is made in Germany, the main disadvantage is that it is expensive. If it had been produced in Russia, it would have been among the average.

Now, in order, about profile systems produced in Russia:

Better than others for:

number of customer reviews,
the number of defects in the supply of plastic profiles,
seal,
conducting seminars, trainings and educational courses for window manufacturers.
Variety of profile systems.

Another advantage is that it sells the profile only to well-equipped enterprises producing plastic windows, which it regularly inspects and issues its certificate to these factories. Therefore, if you have chosen a plant that works with this profile, then the likelihood of getting into an unpleasant situation is less.

I give second place. This company sells its profile only to well-equipped plastic window production enterprises, which it regularly inspects and issues its certificate to these factories. Therefore, if you have chosen a plant that works with this profile, then the likelihood of getting into an unpleasant situation is less.

Well-deserved 3rd place.

Flaws:

There are failures in the supply of profiles, defective profiles are more common than with REHAU and VEKA
Sells the profile to any plastic window factories.

THYSSEN, LG, DIMEX

MOTNTBLANK, PROPLESS, BRUSBOX

Tied for last place in terms of quantity positive feedback people who installed windows, but are very well suited for glazing balconies and loggias, as well as domestic premises. The advantage is low price.

P.S. I haven’t worked with other profile systems, so I can’t say anything about them.

Which plastic window profile is better to choose? Selection tips and manufacturer ratings

The profile is the main element of any window; the durability and reliability of the entire structure depends on it. At first glance, the profile for PVC windows from different manufacturers looks almost the same.

The difference in quality becomes obvious after several months (or even years!) of use, when cheap windows begin to warp and cracks form in them. How to choose a good one plastic profile for windows? How are the products of different brands different from each other? And does it make sense to save on glazing by choosing an economy class profile?

Profile for PVC windows: characteristics and types

The profile is the basis of the entire structure from which window sashes and frames are made. They determine not only the appearance of the window, but also its strength. Common materials for window profiles are wood (cedar and larch) and aluminum.

But most often the profile for windows is made of PVC, or polyvinyl chloride. This profile is reinforced with metal inserts and has air cavities inside that increase the thermal insulation of the structure.

According to the European standard EN 12608 SR “Unplasticized polyvinyl chloride (PVC-U) for the manufacture of windows and doors” and the similar Russian GOST 30673-99 “Polyvinyl chloride profiles for window and door units. Specifications» profiles are classified according to a number of characteristics. In particular, according to the thickness of the external and internal walls, the following are distinguished:

Class A profiles - have outer walls with a thickness of 2.8 mm and inner walls with a thickness of 2.5 mm; they provide best thermal insulation and are considered the best choice.
Class B profiles - have outer walls with a thickness of 2.5 mm, internal walls with a thickness of 2.0 mm; such windows are not only “cooler”, but also 15% less resistant to deformation.
Class C profiles - all others that do not meet standards A and B; no strict requirements are imposed on them.

Note!

There is a so-called “object” profile, which is intended for installation in non-residential production premises. It cannot be used in houses and apartments - due to its thin walls it does not retain heat and is not resistant to deformation.

At first glance, such a profile is no different from a regular one - except that you can see the object marking on the protective film. Often, unscrupulous companies offering very low prices for their products sell windows made from exactly this profile.

Choosing the best profile for plastic windows

It is not easy to determine “by eye” which profile of plastic windows is better, but there are some features that can say a lot about its quality.

Profile uniformity

The plastic must be uniform and absolutely smooth. The grainy surface indicates that the windows were most likely made at home and are fake. The coating should also be uniform, without streaks or gradients.

By the way. To avoid buying a fake at the price of branded windows, pay attention to the factory markings on inside window box. It should have a stamp with the name of the manufacturer and a series of numbers: shift number, device for producing PVC profiles and date of manufacture.

Profile width

Most often, companies offer a plastic profile for windows with a width of 58 mm - this classic version, preferred for residential premises. There is also a profile with a width of 70 mm; this is often installed in high-rise buildings or where the climate is particularly harsh. The 90 mm wide profile is a premium offering and features excellent heat and sound insulation properties. However, not all companies work with such products.

Profile thickness

The profile thickness should be the same, from 2.5 mm to 3 mm. However, thin walls are not suitable for heavy window blocks - in this case, the welding seam is less strong, which means the reliability of the entire structure suffers.

Number of air chambers

The number of cameras also depends on the width of the profile. A 58 mm profile can have a maximum of three chambers - which, however, is quite enough for the windows to retain heat. 70mm - three, four or even five cameras. The last of those mentioned (70 mm) are most in demand for glazing apartments and houses.

The norm for a 90mm profile is six cameras. The more cameras there are, the warmer and quieter the house will be. However, in fairness it should be said that the difference between, for example, a three- and four-chamber package is not so significant.

Number of double glazed windows

The number of air chambers in a PVC profile should not be confused with the number of double-glazed windows. A double-glazed window is several sheets of glass connected to each other along the contour using a special frame and sealants. Sealed chambers with air or other gas inside are formed between the glasses.

Single-chamber double-glazed windows are the lightest; they consist of two glasses and one air chamber between them. Such double-glazed windows are very light, suitable for glazing large openings, so they are often installed on balconies, loggias and terraces. However, they are not suitable for windows due to insufficient thermal insulation.

For a home, cottage, office or apartment, it is better to choose a double-glazed unit consisting of three sheets of glass and two air chambers. Three-chamber double-glazed windows made of four sheets of glass are rare, they are heavy and transmit less light than other types of double-glazed windows.

Such windows are in demand only in the North, where temperatures in winter can drop to -40 o C and below. With more high temperatures There is almost no difference between two- and three-chamber double-glazed windows.

Helpful advice!

When choosing a plastic profile for windows, pay attention to the frame seals. There must be two of them, otherwise condensation will settle under the frame, and this spoils the insulation and creates a favorable environment for bacteria and mold.

Rating of window profiles: comparison of products from key manufacturers

Rehau
One of the most famous companies, which has been producing reliable windows for more than half a century and is considered the main innovator in this field, Rehau engineers are constantly improving the design and configuration of the profile - thus, the company pays great attention to environmental friendliness and energy-saving technologies. The company produces a profile with a width of 60-70 mm. Rehau products belong to the middle class.
VEKA
Another German “giant” whose products are valued all over the world. VEKA produce white and colored profiles that do not fade or turn yellow when exposed to direct sunlight. The seal is made of natural rubber, which does not freeze even when exposed to very low temperatures - a valuable quality for the Russian climate. The line includes models with widths from 58 to 90 mm. In terms of price, VEKA windows are comparable to Rehau.
Trocal
This is a company with a long history, one of the pioneers in the production of plastic windows. The first model was released in 1954. For decorative finishing the company offers a wide range of options - from lamination to acrylic coating. The profile is manufactured using environmentally friendly Greenline technology and provides impeccable thermal insulation. Profile width – 70 mm.
Salamander
This German company is not as famous as KBE or VEKA, but Salamander products are in no way inferior to them in quality. The profile is produced exclusively in Germany, which means that when purchasing such windows, you can count on truly European quality - at a European price. The company produces bags with widths from 60 to 76 mm.
KBE
One of the most popular German brands that produces environmentally friendly windows recommended for installation in children's institutions and hospitals. KBE windows are of high quality and durability (can last up to 50 years!), and the line includes both luxury models and economy options. Profile width – from 58 to 70 mm.
Proplex
Proplex is a Russian company that, despite its youth, has already managed to establish widespread production and significantly modernize window systems. The profile is being developed with the participation of Austrian specialists and taking into account Russian conditions. With very good quality products, the company has so far managed to maintain affordable prices. Proplex offers models in widths from 58 to 127 mm.

This is only a small part of the manufacturers of plastic windows, in fact there are dozens, if not hundreds. Which plastic windows are better? When choosing glazing, you should give preference to well-known brands, but be sure to check all the documentation - famous brands are often counterfeited. Branded windows at too low a price are a sign that they may be trying to deceive you.

Editorial opinion

Even the best windows will not last long if mistakes were made during their installation. Simple economy class windows installed by professionals are better than expensive German windows installed by amateurs.

Which profile of plastic windows is better?

What is a quality profile?

The key to the quality and durability of a metal-plastic window is a high-quality profile. Even if at first glance the entire profile for plastic windows is the same, in reality this is far from the case. Which profile for plastic windows is better, and how to choose the right window will be advised to you by specialists from VEKA Rus.

Certificates

The entire profile from which windows are made is certified. The most significant is the RAL Certificate, which certifies not only the type of product, but also the place of its production. In other words, a profile of the same brand, but manufactured at different factories, will not always have this certificate.

The ISO 9001:2000 quality management system certificate is issued to production facilities that have a well-organized management system in compliance with all technological, economic and organizational requirements typical for production in developed countries. Both Russian VEKA plants have this certificate.

If the profile is wider, is it more reliable and warmer?

The width of the profile is one of its main characteristics. Many window manufacturers promise a couple of extra millimeters to the profile width in their advertising campaigns, but is there really any benefit from them?

The most common offers on the market are:

classic profile 58 mm;
70 mm profile with increased installation width;
VEKA ALPHALINE profile 90 mm.

The width of 58 mm is due to the “classics of the genre” - wooden frames, which were replaced by plastic windows. Today, the EUROLINE 58 mm profile allows us to produce modern warm windows that meet the requirements of most buyers in different climatic zones. Given that correct production and installations, this best profile for windows in any room.

The 70 mm wide profile is a proposal that appeared in the 80s of the last century. Having higher heat-saving and sound-insulating characteristics, this profile is especially loved by Russian consumers. In the product group of VEKA profiles with a width of 70 mm, there are SOFTLINE, SWINGLINE and PROLINE.

The 90mm wide profile is a premium product introduced about 5 years ago. The VEKA ALPHALINE profile allows the use of double-glazed windows up to 50 mm thick and is currently the unsurpassed leader among window profiles with increased energy-saving characteristics.

Note!

The choice of profile width largely depends on the installation location (office window, vestibule door, Entrance door to a store, windows in a country house) and climate.

Now another new product has appeared on the market - the SOFTLINE 82 profile. An innovative multi-chamber system, elegant style and the ability to choose from more than 40 modifications guarantee satisfaction of the needs of the most demanding client. The SOFTLINE 82 system provides the best insulating properties, is fully compatible with 70 mm profiles and can be installed in any home.

Number of cameras

The second characteristic of a window is the number of cameras in the profile. There are three of them in the standard. The first is for removing condensate, the second is for placing a reinforcing metal liner, and the third is for securing parts of the fittings and creating an additional air gap for better sealing of the window. The number of chambers depends on the profile width. So, a 58 mm profile can have a maximum of three cameras, but a 70 mm profile can preferably have four. For a 90 mm profile, the norm is 6 chambers.

Three and six chamber profile systems

Increasing the number of cameras with the same profile width does not significantly change the characteristics of the window. To improve heat-saving characteristics, a wider profile is needed, and not a larger number of partitions in it.

Full package

Another important point- double-glazed window. The number of glasses in a window affects its characteristics and cost. The most common are double glazing, but you can also order single glazed or triple glazed windows.

“Triple” windows are warmer. However, they weigh more and require high-quality installation and stable construction. Single-glazed windows are the coldest. It can be used for glazing unheated balconies, as well as summer houses. Double glazing is optimal for technical specifications, and allows you to maintain indoor comfort all year round.

Profile class

There are two classes metal-plastic profiles. The first, class A, with a thickened external wall, is certified by the RAL system as the optimal profile for windows, doors and frame glazing.

Helpful advice!

The second, class B, is a lightweight profile with a thinner outer wall, the so-called “object” profile. It has a slightly lower cost, but does not guarantee that the characteristics of the window will be maintained throughout its operation.

Windows made from an “object” profile, as an economical option, can be offered by absolutely all manufacturers, but you must remember that such a window may have weaker corner connections, worse dimensional stability, lower energy-saving characteristics, the risk of premature wear of fittings, and a shorter service life.

conclusions

To summarize the discussion on the topic of choosing a profile for a metal-plastic window, we emphasize:

The presence of certificates confirms quality.
According to the installation width, all profiles are divided into two main classes: 58, 64 mm and 70 -76 mm. Within the class, the thermal characteristics are the same. The 68 mm wide profile and the 72 mm wide profile do not differ from each other.
The number of cameras affects the quality of the window only if the profile belongs to different width classes.
The most common is double glazing.
Class A profile is a leader in reliability and quality.

When choosing windows, be able to hear the necessary information and filter out advertising. The quality of your windows depends on your choice. Take your time to make the right choice!
