These products have long been a good alternative to traditional timber window frames. The debate about which plastic windows are better and how to choose high-quality ones are endless. Both supporters and opponents of "plastic" give the most, from their point of view, weighty arguments. And at the same time, no one denies that plastic windows are much more convenient to operate and maintain.
However, few potential Buyers know that from the entire wide range of these designs, not every product is suitable for a particular room. And here some difficulty arises - which profile of plastic windows is best suited for your house or apartment, with all its features - number of storeys, location on the ground, prevailing winds, climate, finally.
Firstly, the same models (profile type) cost differently, depending on the Manufacturer, although there seem to be no structural differences.
Secondly, if it is not possible to mount the "plastic" yourself, then you have to turn to specialists. And numerous companies engaged in the installation of windows specialize only in a specific type of profile. Therefore, they themselves determine what they will mount. But the question is - is this product suitable for us? Let's consider which profile is better for plastic windows based on the 2017-2018 rating.
Which profile of plastic windows is better?
To understand the subtle nuances of the assessment, we had to study a considerable amount of informational texts, a huge number of all kinds of amateur and professional reviews, and conduct a little research of our own.
The product, about whose description so many copies have been broken, is in fact the most ordinary plastic stick, but, however, with a complex surface and internal structure. To give strength inside the profile, there is a metal insert made of galvanized steel, and internal plastic partitions create air chambers that ensure heat retention. Everything. It seems, what is there to argue about? Steel, it will remain steel, so as not to be done with it, and the plastic used by all companies is the same - polyvinyl chloride (PVC). It follows that the window profile of any production must be of the same quality. Is it so? And how do you choose the best of the same by definition?
Profile selection criteria
Country of origin of the profile
Any company that recycles a window profile indicates its origin. In this case, very often you can find the word "German" in the descriptive part. We recommend that you clarify what is meant by this word, since to them sellers like to justify the high price of the finished window. The lion's share of this profile is produced in Russia using German technology. In this case, relatively cheap energy resources and labor are used, therefore, the cost of the product should differ from the profile produced in Germany.
Number of heat-insulating chambers
By far the most important criterion. It is believed that the more chambers, the better the thermal insulation. However, do not forget that an unnecessarily large number of chambers can lead to the fact that the thermal conductivity coefficient can, on the contrary, increase, due to the plastic partitions, which will act as a cooling radiator. Therefore, we must pay attention to the following criterion.
Profile width
When choosing a profile for a living room, it is better not to save on this parameter. Everything is simple here, the wider, the warmer. It should only be noted that small-chamber wide profiles can be easily deformable, because have few stiffening ribs.
Number of chambers of a double-glazed window
We advise you to choose only two-chambered ones, even for glazing loggias - do not forget, a miser pays twice. However, the choice of a double-glazed window is a topic for a separate article.
Reinforcing steel insert
It happens with an open or solid circuit. If there are no restrictions on strength, then we advise you to choose an open one, it is warmer.
ISO 9001 certificate
Gives a guarantee of control over the production of window profiles according to the quality management system.
Useful Tips
Choosing the “right” profile is not a guarantee of the quality of the entire window structure. The main thing is who made it? Well-known Manufacturers of profile products only supply them to the market, and many organizations are engaged in complete assembly (profile + double-glazed windows), some of them - and installation. By the way, how well do they do it? The question is very significant.
Therefore, if a defect is discovered during operation, the same KBE has absolutely nothing to do with it. Claims - to the Manufacturer of the window itself (or the Installer). Therefore, before purchasing a product or concluding a contract for its installation, it is advisable to collect some information. Much can be learned through acquaintances, from the Internet, and based on the reviews, and draw appropriate conclusions.
By the way, experts point out that there are no specific quality criteria for window profiles. For example, quality factor, strength. Who figured it out, by what criteria the testing was carried out is unknown (again the question of the "promotion" of the product).
Practice shows that “quick and cheap” offers often turn into big problems in the future. A plastic window is a product of long-term operation, so there is no point in saving too much on this.
On many sites there are articles where the profiles of individual manufacturers are compared and "prize" places are almost distributed. We consider this approach to be incorrect and just want to remind the reader that by definition there is no universal “remedy for everything”. In addition, the information on many sites, unfortunately, is just a marketing gimmick, hidden advertising of their products and veiled "groaning" of competitors.
The best profile is the one that neighbors and colleagues speak well of when they talk about their windows that have already been standing for several years. Yes, and the information given is quite enough to understand for yourself what is best for glazing your home.

Profile of SOK Syzran
Listed as a permanent figure in Internet ratings. From the information gleaned on the website of the company SOK (Samara Window Structures), you can easily find out that the company does not have its own production of window profiles. The "branded" profile is manufactured at the Profine concern plant (see KBE). This means that the profile is produced in accordance with international requirements and is ISO certified, which is not bad. But the question immediately arises about the high cost of windows from this profile, the price of which is much higher than KBE windows. The choice of configurations is very small, only two types:
- Corporate profile SOK-470 - 4 chambers, width 62 mm
- Branded profile SOK-570 - 5 chambers, width 72 mm
What plastic windows are better to install?
And in the end, the main thing is that the best profile is a careless window manufacturer or an armless installer who can turn it into disgusting trash. Therefore, before ordering windows, consult with neighbors, friends or simply acquaintances who have already contacted the company of your choice. Remember that a profile is just a piece of plastic, which, although it is an important component of a window block, nevertheless, its choice must be justified in combination with factors such as reliable fittings, good double-glazed windows and the conscientiousness of the craftsmen.
The companies Rehau and Proplex have a good reputation in the modern market of plastic windows in the middle price segment, but which is better - the indisputable and respectable German quality, time-tested, or Russian ergonomics according to Austrian technologies - it is difficult for an ordinary buyer to understand. Judging by the reviews on the network, the products of both companies are worthy of attention. To understand all the intricacies of choice in order to wisely spend savings and get the warmest, quiet, strong, durable, safe plastic windows, a detailed comparison of their designs will help.
Plastic windows from PROPLEX-Premium, Exprof and PROPLEX-Lux profiles
Having chosen one combination of a profile for a window frame and, in fact, a double-glazed window, all windows of the same type are ordered. We answer: the confidence that with such windows your attic will become an impregnable fortress for the intrigues of bad weather. The second important element of wooden euro-windows is a two-chamber double-glazed unit, which consists of three parallel glass sheets, connected by a hollow aluminum profile.
Thirdly, plastic panels retain heat better than their wooden counterparts. A trip to the firm is the best way to be sure of the decency of the advertiser. Due to the widest color range of fabrics used and the ability to adapt to any shape of the window, they successfully fit into any modern interior and go well with the fabrics used for decorating windows.
As such, they can be wiped off while staying at a safe distance from the edge of the balcony railing ..
Rehau and Proplex product range
To get a more complete picture of the strengths, weaknesses of the products of Proplex and Rehau, it is worth starting with a brief historical background and acquaintance with their range.
Rehau Profiles

Proplex profiles
The Russian company Proplex is one of the five largest manufacturers of profiles for plastic windows in the country. Its plant is located in the Moscow region and has been operating since 1999. The production is carried out using unique Austrian technologies. Today Proplex's offers are:
- OUTLINE - 42 mm two-chamber profile from Proplex, which has a not too high coefficient of resistance to heat transfer of 0.405, but which, in combination with a glass unit up to 22 mm, is quite enough for the second line of glazing (balconies, loggias, verandas, terraces) or non-heated non-residential premises.
- Basis- affordable, reliable 58 mm three-chamber design with decent heat-saving properties (0.64 m2 ° C / W). It can be used with a glass unit up to 32 mm for glazing office or industrial premises, as well as residential buildings located in warm areas or operated mainly in the summer (summer cottages). Can be combined with anti-burglar fittings.
- Optima- 58-mm budget three-chamber version, which has basic safety, but at the same time warmer (0.70 m2 ° C / W) due to internal structural features (special arrangement of chambers and reinforcing liner).Designed for use with a double-glazed window up to 34 mm for glazing living quarters, withstands significant temperature fluctuations.

Which profile of plastic windows is better?
To date, companies engaged in the production of plastic windows have presented many different modifications of windows from a huge number of PVC profiles. In this article we will figure out which plastic profile is better for glazing your home.
As a rule, most often people, under the influence of advertising, want their windows to be glazed with the profiles of companies that actively promote their brands - Exprof. KBE, Proplex, LG, etc. But as the result has shown - a big name does not mean good quality.
There are many differences between brands of window profile systems. Modification of the PVC profile is responsible for the rigidity of the structure, in addition, the profiles differ in geometry, the number of chambers, which determines the thermal insulation properties and sound insulation.
PVC window profiles must comply with GOST 30673-99 "PVC profiles for window and door blocks".
One of the most important characteristics is the number of internal chambers. Most often, companies offer ready-made windows with a 3-chamber structure. Such windows fully satisfy the needs of the customer, and have shown themselves excellently in the climatic zone - the Volga region. In addition to the 3-chamber system, 2, 4 and 5-chamber PVC profiles are presented. The two-chamber profile is practically not used for glazing residential buildings and apartments, its characteristics are noticeably inferior to the 3-chamber system and do not meet the stiffness standards.
Systems of a four-chamber and five-chamber profile are usually used for glazing buildings in harsh climatic zones, as a rule, these windows are supplied with energy-saving or 2-chamber double-glazed windows.
PVC profiles from different manufacturers can also be compared in terms of thickness, maximum width of the glass unit, number of seals, heat transfer and noise resistance. The following table will present systems that fully meet the requirements of the thermal protection coefficient. The best indicators of this ratio have PVC profiles - KBE, Proplex, Novotex. These plastic profiles can be considered the warmest, and they have the best noise protection.
The table below shows the main characteristics of the physical and mechanical properties of plastic profiles of a 3-chamber system.
As can be seen from the table, the indicators of all the given PVC profiles correspond to the norm. The profiles KBE, Novotex, Proplex have the highest tensile strength and softening point, and Novotex plastic windows have the highest impact strength.
Remember that when choosing plastic windows, the most important thing is to take into account the climatic conditions of your region and the type of room where you are going to install them.

Ordinary glazing - installation on the balcony of frames (metal, wood, plastic) with glasses inserted into them (ordinary, tinted, stained glass, etc.).
Moreover, you can order not only transparent glasses, but also tinted ones. In this regard, when installing such windows, you need to pay a lot of attention to the rules and technical conditions of installation. These parts are also designed to strengthen the window, which can withstand much higher loads (this is how, for example, suspended facades are installed).

The main differences between Rehau and Proplex
Windows from the Rehau profile differ significantly from Proplex products, which becomes visible even with a superficial comparison of competitors' offers:
- The range of the German concern is much wider, and for 60 years of vigorous activity it has developed more branded and unique manufacturing technologies than the Russian one for 20 years of existence on the market.
- The minimum thickness of the window profile for Proplex is 58 mm, it has 2 or 3 chambers, the largest possible width of a glass unit is 24-34 mm, the resistance to heat loss is from 0.405 to 0.70, and for Rehau - 60 mm, 3 chambers, 0, 64-0.65 m2 ° C / W.
- The maximum performance of the products of the Russian manufacturer - frame 70 mm, 4 or 5 chambers, glass unit 42 mm, resistance 0.80 - 0.82, German - 80-86 mm, 6 chambers, glass unit 51-54 mm, resistance 0.90 - 1 , 05.
- The Proplex company has a profile with minimal characteristics and cost in the lineup, intended for secondary glazing, for example, balconies or verandas, that is, in those places where aesthetics or cost savings are more important than warmth and silence.
- Rehau has a unique code on each product by which you can check the originality.
Plastic windows from the Brusbox, Exprof, PROPLEX-Premium profile
The wood species is also important. Condensation and moisture can form inside, between the glass panes. Spikes and grooves must be cleaned of dust and old glue.
And ventilators are fresh air with reliably closed windows .. In the era of the emerging post-industrial society, a person again turns his gaze to nature. The pattern of these lattices resembles the finest lace ..
In cold windows, single glass with a thickness of up to 12 mm is used. It can be of the required thickness for the client (double-chamber, single-chamber), while the glass is produced in compliance with advanced technologies. The entire load during a burglary attempt must fall on the outer walls.
And we have?! From year to year, with the arrival of the next winter, we are painfully struggling with the same question: how to caulk the windows so that it doesn't blow? It's good if you have plastic profiles with double-glazed windows, seals and other bells and whistles. It does not destroy the architect's idea in old and elite houses and does not aggravate the diversity of facades of ordinary apartment buildings .. But they have revealed the traditional "disease" for this capricious material: if even a small crack formed and moisture got into it, the windowsill "swelled".
If a room with plastic windows is not ventilated every now and then, then the air in it stagnates and becomes stale. Air exchange. Everyone has the right to solve this issue in his own way.
But the main difference is that in domestic frameless glazing systems, glass sashes are attached by means of movable carriages not only to the upper, but also to the lower guide aluminum profile, so that the sash acquires four points of support at once - above and below. Remains of glue are removed with a spatula. It was necessary to inquire in the most attentive way with which profiles the firm works.
This glass is safe: if, God forbid, it breaks, it will not stick out with sharp edges, but gently crumble, turning into small "cubes". Usually, when buying windows, sellers themselves advise which fittings to give preference to in each specific case separately.

Comparison of Rehau and Proplex profiles by characteristics
The main thing that you need to pay attention to when choosing a manufacturer is the technical characteristics and features of its products. To decide between Rehau and Proplex, it is necessary to conduct a detailed comparison of their profiles.
To lean in favor of one of the manufacturers, you should compare their offers for the following characteristics:
- wall thickness of window frames;
- number of cameras;
- the quantity and quality of the sealing contours;
- type of reinforcement;
- mounting width;
- thickness of double-glazed windows;
- appearance;
- operational period.
Waterproofing and quality of used seals
Good waterproofing is a guarantee that the window will subsequently not fog up, accumulate condensate, "grow" mold, and freeze.Waterproofing of pvc windows is carried out using a special seal located in contours, at Proplex, for example, in most structures there are two of them. Rehau also has basically two sealing circuits everywhere, except for the latest Geneo novelty, in which there are three of them.
An important role is played by the material (mainly EPDM) of the seal, as well as its shape. Rehau has two-lobed sealing gum without internal cavities. It does not collect moisture, does not stretch, does not age, retains all its properties unchanged, being in the temperature range from -40 to +120 degrees.
Sound and heat
First of all, a plastic window should be warm, and secondly, it should be good to isolate the room from street noise. These properties are determined by the structure of the structure - its depth, wall thickness, number, size, location of air chambers, quality, quantity of the sealant. If we compare the maximum indicators of thermal insulation of plastic windows Proplex and Rehau by class, then the Russian manufacturer in the premium category is noticeably inferior to the German one - 0.81-0.82 versus 0.95-1.05. In other classes, the difference in resistance to heat transfer is not too obvious:
- economy - 0.64-0.65 for Rehau versus 0.64-0.70 for Proplex;
- the standard is 0.80-0.85 for the Germans versus 0.80 for the Russians.
As for sound insulation, Rehau also keeps its reputation here. In their budget models, this figure is 30-35 dB, in more expensive models - 45-47 dB. Proplex, on the other hand, does not specify the sound insulation parameter for the types of pvc profiles, but claims that in any of them it is at least 30 dB.
Reinforcement type
The strength of the window structure is determined by the presence of a reinforcing base inside it, made of steel tape with a thickness of at least 1.2 mm for small and at least 1.5 mm for large windows. An important nuance is the shape of the reinforcing insert. It can be P, G, G-shaped or square. The last is the strongest, but the G-shaped base is only slightly inferior to the square one.
Basic models of the Proplex window profile are made with U-shaped, and premium versions - with square reinforcement. For Rehau, the situation is similar - in budget variations, P-reinforcement, in more expensive G-reinforcement. One could count as a draw, but thanks to its latest development, the RAU-FIPRO fiber reinforcement technology, embodied in Geneo, the German manufacturer is taking the lead. The bottom line is that the reinforcing mesh is placed in the structure itself during its production, so additional reinforcement with a steel liner is no longer required. At the same time, the strength characteristics remain the same, but the weight drops by almost half, which expands the range of application of such frames and extends the service life of the fittings in them.
Installation depth of PVC profiles
The installation depth is the thickness of the frame in the opening. All properties and technical parameters depend on it. Considering the proposals of competing manufacturers, the following can be noted:
- German budget models have a frame of 60 mm, Russian ones - 58 mm;
- Rehau also has designs in 70, 80, 86 mm with heat conservation coefficients 0.80-0.85, 0.95, 1.05, the deepest Proplex profile - 70 mm, heat saving index - 0.80-0.82 ...
It follows that Rehau products are significantly ahead of Proplex products in this parameter.
Profile outer wall thickness
The thickness of the outer wall of the window frame largely determines its strength, durability, wear resistance, as well as resistance to various mechanical damage. World standards and Russian GOST (30673-99) set out the minimum values of the wall thickness from the outside for classes A (the best, at least 3 mm in the world, from 2.8 mm in Russia), B (from 2.5 mm), C (less than 2.5 mm).
At Rehau, all standard and premium types have a wall thickness of 2.8, 2.9, 3 mm, respectively, belong to the highest class. Walls in budget variations with a thickness of 2.7 mm, which allows them to be ranked as class B.At the Proplex plant, only the Premium pvc profile belongs to category A, the rest to B or even C.
Number of air chambers
The main technical characteristic of the window profile is the number of chambers, which for Proplex varies from 2 to 5. Rehau has options with 3-6 chambers. Air chambers, more precisely, their number and size, are responsible for keeping the rooms quiet and at a comfortable temperature. The more there are, the higher the energy-saving and noise-insulating performance.
For Proplex windows, the leaders among the proposals (Hit, Premium) have five chambers, and the heat savings rate is 0.81-0.82. Rehau is doing much better. Their five-chamber Delight, Brillant, Grazio have heat loss resistance equal to 0.80, 0.81, 0.85, and six-chamber Intelio, Geneo - 0.95, 1.05. The difference is obvious.
Maximum thickness of a glass unit
The thicker the glass unit is used in the window, the quieter and warmer it will be in the room. Thick double-glazed windows can only be installed in a deep frame.
The German concern has offers:
- 60 mm for double-glazed windows up to 32 mm (Blitz, Euro);
- 70 - 41 mm (Delight, Brillant, Grazio);
- 80 - 51 mm (Intelio);
- 86 - 54 mm (Geneo).
The profile from Proplex lags far behind in this regard, it has:
- 58 mm and allows you to install a double-glazed window 24–34 mm (OUTLINE, Basis, Optima);
- 70 - 42 mm (Comfort, Premium, Hit).
Appearance and service life
Competitors' windows also differ in appearance. Rehau's designs are as smooth as possible, shiny, glossy with a bright white surface that does not turn yellow, does not turn gray, does not fade over time. At the same time, dirt practically does not linger on it, which makes it possible to replace the thorough washing of the frame with wiping it with a damp cloth just a couple of times a year.
The profile for plastic windows from Proplex does not have a bright white color, it is rather milky with a semi-matt non-shiny surface. Looks stylish, but somewhat dull. But on it scratches are practically not visible. The dirt retains, but is washed off quite easily.
In terms of service life, both companies guarantee that the profile will retain all its quality characteristics for 60 years.

It is also important to find out the parameters of the durability of the adhesive joints and the possible deviation from the nominal geometric proportions. This frame is solid, not divided into parts. The basis of the binding is a frame-binding with folds for glass, they are fixed with small blocks-glazing beads with the help of small nails.
Skylights, also made of laminated veneer lumber and double-glazed windows, are used for glazing attics. After removal, wipe the window. lay insulation around the entire perimeter of the balcony, as well as on the floor and ceiling;
First, you need to determine the brand of fittings, which is written on the metal lock. Euro-lining and Euro-floor are the most popular materials for finishing balconies. Secondly, the dubious appearance - restoration will not be much cheaper than replacement.
Battery, Greater Greater !. By applying metal oxides or crystals to the glass surface, solar-protective or heat-saving glasses are obtained. When planning the number and type of flaps, it should be borne in mind that flaps that open in a pivoting way should not be wide, so as not to “eat up” an already not too large useful area when open balcony.
The need for painting, etc. The thermal conductivity of this gas is lower than that of air, so that the windows save heat better .. As a rule, aluminum profiles look catchy (since they are not painted), and are used for window frames on balconies and terraces , verandas, as well as stained-glass windows and showcases ..
Wooden windows do not have this disadvantage. But the price is made up of many components. On the inner plane of the upper loop of the designer G-U, a groove was provided for a rubber seal, which is evenly pressed by the loop, and does not bend at the edges.
How to put a window block. If the new window frame has tabs at the ends of the rails, cut them off. The dimensions of the quarter depend on the construction of the walls.The first thing to remember is that frameless glazing makes it impossible to increase the room temperature.
