Plastic window profiles: what do you need to know to make the right choice?
The key element of a plastic window is its profile. In fact, the strength, reliability, durability of the entire window structure, as well as the comfort and convenience of its use depend on its choice. The modern market is literally inundated with such goods of all stripes and brands, and in such a situation a completely logical question arises: how to choose the profile of plastic windows? How can you determine which one is best for your specific situation, and how to avoid making a mistake and regretting your decision? In this article we will try to give you key information that will help you find the answer.
Plastic profile Grunder 60
GRUNDER 60 is a budget option for plastic windows of European quality. They have excellent technical characteristics, reliably protect against noise and retain heat. Such double-glazed windows are the best option for glazing a balcony, apartment or office.
The high quality of Grunder 60 windows is confirmed by certificates of conformity, and the absence of harmful lead ensures increased environmental safety. High technical characteristics are harmoniously complemented by an elegant design that will be relevant in any interior style.
Main types of profiles
So, if you want to figure out how to choose plastic windows: which ones best suit the parameters of your room, then first you should understand their main types. There are four of them (three main and one additional):
- Class A. This is traditionally the best option, the thickness of the internal walls is at least 2.5 mm, and the external walls are at least 2.8 mm. Class A profiles are characterized by good thermal insulation and resistance to deformation.
- Class B. The thickness of their internal walls is from 2.0 mm, and the external ones - from 2.5 mm. Accordingly, they demonstrate slightly lower thermal insulation abilities and are also less resistant to deformation.
- Class C. These are window profiles that do not correspond to the characteristics of the structures of the two classes indicated above.
- Object . This is the name of a special type of profiles with thin walls, which very easily allow cold to pass through and become deformed under adverse external influences. Such options are intended exclusively for use in industrial non-residential premises, and most often - in principle, they do not involve the presence of people.
Accordingly, if we talk about which window profile to choose from the standpoint of their class, then the best option would be class A. In some cases, class B options are also suitable for residential premises.
Technical features
launches two variants of Gründer brand window profiles on the market:
- Five-chamber.
- Three-chamber.
In the first case, the consumer receives a system with a profile thickness of 70 mm, which allows it to be installed in regions with particularly frosty winters. The second option has a profile thickness of 60 mm. It retains all the characteristics of the five-chamber version, but is more affordable.
As for the wall thickness, it is also available in two versions:
- Class "A": 3 mm.
- Class "B": 2.8 mm.
The technical characteristics of the Grunder profile are relevant not only for window structures. Door groups are produced with the same parameters, so we often fulfill orders for installing the Grunder profile on balconies and loggias.
Aesthetic characteristics
Regardless of the wall thickness and price category, the Grunder window profile is marketed in white. Moreover, due to the unique frequency of the shade, the profile received a second name: “blue ice”. Grunder window designs and door groups have unsurpassed design characteristics. Snow-white, strict and elegant, this profile can decorate any interior.
The classic, clear proportions of the product ennoble the room, imbuing it with grace and nobility. At the same time, the snow-white shade of Grunder does not change over time, since the profile is endowed with ultraviolet resistance.
The frames are made of material that is not susceptible to aggressive chemical environments. They can be cleaned with any detergent, avoiding metal brushes.
Resistance to acidic compounds makes it possible to install the system even in industrial areas where the atmosphere is poisoned by industrial or factory exhaust. Nothing can damage the original aesthetic properties of Grunder. “Blue Ice” will remain in the same design after three decades.
The front side has a bevel of 15 degrees, which gives the design a special elegance. It is also important that profile lamination allows you to stylize the window in any color scheme.
The most popular options that are often ordered from Oknotech specialists:
- Under the tree.
- Under natural stone.
However, the flawless glossy surface of the frame in an ideal white shade is attractive in itself without additional decoration.
Soundproofing and thermal insulation
The main quality for which Grunder is valued by consumers all over the world is its increased sound insulation and heat insulation qualities. All products of this brand comply with RAL and GOST criteria.
Heat transfer of the product: 0.63m2°C/W, so Grunder window designs are ideally suited to the Russian climate. Experts enhance the insulation using high-quality sealant. The double-circuit seal is ideal protection not only from moisture, but also from drafts.
Security level
Each offer on the window and technology market is valued not only for its ability to retain heat indoors, but also for its level of safety. In this regard, Oknotech window frames can be called a quality standard. The window structure does not contain lead. Calcium and zinc compounds are used as stabilizers. In addition, the design is free of other toxic compounds. This is explained by the fact that the developers put the environmental friendliness of their product at the forefront.
Therefore, Oknotech window frames are appropriate for use:
- In educational institutions.
- In the institutions of the Ministry of Health.
- In residential buildings.
The smell of heated plastic is not characteristic of the Grunder window profile, even with intense exposure to ultraviolet radiation. This is a truly environmentally friendly, aesthetic and practical product.
In addition, the Grunder profile has a fire safety certificate and meets sanitary and hygienic standards. Caring for the window frame is not difficult because it is resistant to corrosion processes. Microorganisms or bacteria do not take root inside the profile due to the moisture resistance of the materials used.

Which window is better to choose: profile characteristics
Just choosing a class may reduce the number of options, but not by much. To finally decide which PVC windows are best to choose, you will also need to evaluate potential options in terms of several characteristics.
Number of chambers and profile width
A chamber is an area with a hollow air space enclosed between partitions. The more chambers in a profile, the greater its thickness, and the higher the thermal insulation properties it has. Typically, the number of chambers varies from 3 to 6, with a three-chamber profile having a thickness of about 60 mm, and a six-chamber profile about 90 mm. If we talk about which plastic windows to choose for a private house or apartment, then it is better to give preference to profiles with 5-6 cameras.
Profile wall thickness
We have already mentioned this characteristic when we talked about the classes of plastic window profiles. The thickness of the walls is important, first of all, in order to guarantee the resistance of the structure to deformation. The larger it is, the stronger the profile. It is highly desirable that its outer walls have a thickness of at least 3 mm, otherwise the long-term operation of the windows in the Russian climate will be doubtful.
Number of double glazed windows
A double-glazed window is sheets of glass hermetically connected to each other, between which there are chambers with air or other gas. Do not confuse the number of double-glazed windows with the number of cameras in the profile. The degree of thermal insulation of the entire structure, and in addition to it, the degree of light transmission also depends on this characteristic. Therefore, answering the question of which plastic windows to choose for a private house, apartment or office space, the team of Stroy.Direct specialists recommends choosing two-chamber options (these are three sheets of glass and two air cavities between them). On the one hand, they are quite good in terms of heat retention, on the other hand, they do not absorb too much light and weigh relatively little.
Authenticity
This is not so much a characteristic of choice as a parameter that needs to be checked when purchasing profiles directly. Firstly, there must be a stamp on the inside of the box indicating the brand, shift number, equipment used to produce the structure, and the date of its release.
In addition, it would not be superfluous to inspect the products and evaluate the quality of the plastic. It should be uniform and one-color, without streaks, smudges or graininess. If you notice such imperfections, you should refrain from purchasing, since they indicate violations of the technology made during the manufacture of the double-glazed window.

All about windows
Profile system
is a series of profiles developed for specific purposes of use (for example, budget or luxury, for different climatic conditions) and possessing certain qualities (for example, specific design, profile and glass width, increased heat and sound insulation, burglary protection). About
Profiles
– parts of window blocks made by extrusion, with specified shapes and cross-sectional dimensions.
Profile width
– the largest size between the front outer and inner surfaces of the profile.
Profile height
– an indicator characterizing the maximum cross-sectional size of a window profile in the perpendicular direction relative to the width of the profile.
Camera
– hollow compartments inside the window profile, separated by partitions. The camera may consist of additional sub-chambers. Profile chambers and subchambers can perform various functions: for installing a reinforcing profile, as self-ventilation channels, and others.
fold
– part of the profile surface formed by the protrusion of one of its parts.
Backlash
– the gap between the sash and the frame of the window unit, established based on the conditions of normal operation of window fittings
Narthex
– the place where the sash connects with the frame bars (main vestibule), with the impost (impost porch) or with the sash (impostless, frame porch).
Floating
- a protrusion in the narthex assembly, formed by the protruding part of the frame (sash) and overlapping the sash (frame) by the size in the narthex under the overlay.
Reinforcing liner
– a profile steel element installed in the internal chamber of the main profile to absorb operational loads.
Profile combination
– a connection unit for mating profiles (for example, a frame profile - a sash profile with a glazing bead, an impost profile - a sash profile with a glazing bead, a sash profile with a bead and a glazing bead - a sash profile with a glazing bead).
Main profiles
– profiles of frames, sashes, imposts, frames, which perform a strength function as an integral part of window and balcony door structures.
Additional profiles
– profiles that do not perform a strength function as an integral part of window and balcony door structures.
Glazing beads (layouts on glass)
– additional profiles intended for fastening double-glazed windows. Glazing beads can be manufactured with a co-extruded sealing gasket.
Connection profiles (connectors)
– profiles designed for blocking window and balcony door frames with each other in structures consisting of two or more products. Connectors can connect box profiles at different angles and are selected taking into account strength requirements.
Expansion profiles (expanders)
– profiles designed to increase the height of the window frame profile.
Gorbylki
– profiles intended for dividing the glazing fields of sashes.
Decorative overlays
– overhead decorative profiles, glued to the double-glazed window from the inside and outside and forming a false binding.
Low tides
– profiles designed to drain water from the window structure.
Cladding profiles
– profiles for finishing window slopes (corners, trims, trims, etc.). Cladding profiles can form various systems.
Adjustable ventilation
— organization of ventilation of rooms with different air exchange rates due to design solutions of products.
Self-ventilation
– a system of limited air exchange through the channels of profile chambers or through climate valves built into window units in order to regulate the air humidity in the room and prevent condensation on the internal surfaces of the windows.
Durability
– characteristics of products that determine their ability to maintain performance qualities for a given period, confirmed by the results of laboratory tests and expressed in conventional years of operation (service life).
Double glazing / Infills
Double-glazed windows are three-dimensional products consisting of two or three sheets of glass connected to each other along the contour using spacer frames and sealants, forming hermetically sealed chambers filled with dried air or other gas.
Double-glazed windows depending on the number of cameras
divided into types:
- SPO – single-chamber
(two glasses), - SPD – two-chamber
(three glasses).
Sandwich panel is an opaque filler made of two sheets of plastic with a layer of thermal insulation boards made of foamed polystyrene. Has high heat transfer resistance.
The chambers of double-glazed windows can be filled with:
- dry air,
- inert gas (argon - Ar, krypton - Kr, etc.),
- sulfur hexafluoride (SF 6 ).
Depending on their purpose, double-glazed windows are divided into types:
- double-glazed windows for general construction purposes,
- double-glazed windows for construction purposes with special properties,
- shockproof,
- energy saving,
- sun protection,
- frost-resistant,
- noise-proof.

What are the main advantages of plastic windows?
Modern plastic windows have a number of distinctive features:
- durability,
- resistance to all types of weather influences,
- tightness and sound insulation,
- fire safety, since the plastic formulation includes substances that do not support combustion,
- environmental friendliness - the production of plastic windows is harmless and does not pollute the environment. In addition, in the production of window profiles, a non-toxic CaZn formulation is used, which is environmentally safe for human health.
In addition, plastic windows do not require special care and retain their original appearance throughout their entire service life.
What is the main difference between modern wooden and aluminum windows?
All modern windows, regardless of the materials used, have excellent performance characteristics. Wooden windows have an attractive appearance and look very solid, but their cost is quite high. Such windows require more frequent and careful maintenance. Aluminum windows are excellent for glazing non-residential and utility rooms, but they are not recommended for installation in residential premises, since they do not protect rooms well from freezing due to the fact that aluminum (like any metal) transfers heat well.
What is the window made of?
The main elements of a window are the frame, sash, fittings and glass unit.
Frame
– a fixed plastic part of the window on which the sashes are attached. The frame consists of a plastic three-chamber or five-chamber profile, inside of which there is a galvanized steel reinforcing profile having a U-shape.
Sash
– necessary for the window to have opening parts. The sash, like the frame, consists of a three- or five-chamber plastic profile, inside of which there is a U-shaped galvanized steel reinforcing profile.
Double-glazed window
– glasses hermetically connected to each other in a special way. Depending on how many glasses are used, a distinction is made between single-chamber (two glasses and one chamber between them) and double-chamber (three glasses and two chambers) double-glazed windows. Along with the profile, the double-glazed window is responsible for the thermal insulation, safety and soundproofing of the window.
Accessories
- these are all the moving mechanisms of the window: hinges, handles, locks, latches, as well as other parts hidden from view inside the profile. It is needed in order to ensure the connection between the frame and the sash, as well as to ensure a tight fit of the sash to the frame in order to avoid blowing at the junction. In addition, the fittings allow you to open the window sash in various options: rotary or tilt-and-turn. In modern windows, fittings are responsible for the safety and reliability of the window structure - after all, the fittings have an anti-burglary function.
Window structures are made from a set of standard profiles.
There are several main types of profiles:
- Frame profile
- used to create the main structure (frame), usually along the contour of the entire window. - Sash
- sashes and other opening elements are made from it. - An impost
is a frame profile used for the rebate of sashes and the hanging of sashes in three or more casement windows. - Glazing bead
is a plastic strip that holds the glass unit in the window. - Flashing
is a flat and wide profile installed outside the window and designed to drain rainwater from the window. - Slope
is a flat and wide profile used for neat finishing of the side surfaces of a window opening.
What is the average lifespan of a window?
Service life – 40 years. Tests have shown that the service life, for example, of the Gründer window profile actually exceeds 40 conventional years of operation.
Is it true that plastic windows can come in a wide variety of shapes?
This is true. The window profile allows us to produce windows of various shapes, from rectangular to complex arched structures.
Can windows only be white?
As a rule, windows are snow-white with a matte (non-glare) surface. Such windows look very neat and modern. If you want to give individuality and a fresh look to familiar interiors, you can choose laminated windows. Such windows are harmoniously combined with the furniture, the overall color scheme, and the design of the facade. The rich color palette and texture of laminating films, including those imitating the texture of valuable wood species, will allow you to bring to life even the most daring design projects. The profile can be laminated on one side - external or internal - or on both. Lamination films are durable and resistant to atmospheric fluctuations and UV radiation.
Can plastic turn yellow over time?
A high-quality profile does not turn yellow. Windows from German, Austrian and Finnish manufacturers are of the highest quality. A low-quality profile could not become known: window manufacturers would quickly abandon such a profile.
How to properly care for windows?
Ventilation of the room.
Ventilate all rooms 3-4 times a day for 15 minutes and every morning for 20-30 minutes. During ventilation, windows should be opened as wide as possible (rather than tilted), which ensures effective ventilation in a short period of time. Do not lower the room temperature below 15 degrees C. Plastic windows require almost no maintenance; they only need to be occasionally cleaned and the moving parts of the fittings lubricated.
Primary cleaning.
After installation, it is necessary to remove drops of cement and whitewash. Otherwise, seals and parts may be damaged.
Regular cleaning.
For cleaning, only non-abrasive cleaning products are used to avoid damaging the profile surface. Also, do not use solvents, which can damage the profile and seals.
PVC profile frame care.
The chemical composition of PVC is unstable to acid solutions. Therefore, the frame must be cleaned using a regular soap solution, or using special detergents that do not contain solvents, abrasives or acetone. It is better to purchase the cleaning product in liquid form. It is applied with a soft linen cloth to the surface of the frame and left until completely dry. Then rub the frame with a dry or damp cloth. Do not hit or scratch the outer surfaces of the PVC profile.
Caring for rubber seals.
The seals are made of modern material, which is nevertheless subject to natural aging. To extend its service life, i.e. maintaining elasticity and the ability to retain any drafts and moisture, it is necessary to clean them from dirt once or twice a year and wipe them with special means. For processing, use a highly absorbent cloth. After this, the seals on your window will remain elastic and water-repellent.
Window handle care.
If the window handle is loose, you need to lift the decorative strip underneath it and tighten the screws.
Drainage
Each plastic window has drainage channels to remove moisture accumulated inside it. The drainage channels are located at the bottom of the frame - they can be easily found by opening the sash. It is necessary to monitor the condition of these channels and clean them from dirt from time to time.
Caring for fittings.
Your windows are equipped with high-quality fittings. To increase its service life and maintain an impeccable appearance, you should lubricate all moving parts at least 2 times a year with oil that does not contain acids or resins. Also, these products should not destroy the protection of elements from corrosion.
Pros and cons of Rehau profiles
Familiarization with the range of Rehau profiles helped to get an idea of the options for future windows, as well as to see the difference in models. To complete the picture, it is worth analyzing the pros and especially cons of the company’s products.
Pros of profiles
A comparison of Rehau profiles with offers from other popular manufacturers (Veka, KBE) made it possible to identify their main advantages:
- A huge range of models , each of which has its own purpose. Both people with average incomes (economy class products) and financially secure buyers (standard and premium class models) can easily choose the best option for themselves.
- Excellent thermal insulation performance , even for basic models - maximum - 1.05 m2°C/W.
- High noise insulation characteristics - up to 47 dB.
- The strength of the profile is at the highest level , which means that windows made from it will be safe throughout their entire service life.
- The use of innovative technologies (RAU-FIPRO) allowed the manufacturer to reduce the weight of the frame, which expands the range of applications of its windows and causes less wear on the fittings.
- The waterproofing of Rehau window structures, in comparison with the products of all other manufacturers, occupies a leading position in terms of performance, and all thanks to the special shape of the seal (double-leaf).
- The special composition of the profile (over 50 components versus 20 for most competitors) makes it stronger and ensures the preservation of whiteness and shine throughout its entire service life.
- The particularly smooth surface of the profile contributes to its less contamination, that is, it significantly facilitates maintenance - the windows practically do not need to be washed, it is enough to wipe them with a damp cloth 1-2 times a year.
- The manufacturer provides a maximum guarantee for the profile - 60 years, confirmed by numerous tests in an accelerated time chamber.
Disadvantages of profiles
A comparison and description of Rehau windows will be incomplete if we are silent about their disadvantages, namely:
- Lots of fakes. The best has always been counterfeited. Rehau products did not escape this either. However, the company has found a way to protect its customers from scammers. Each of their products is marked with a unique serial code. To check the originality of the profile, call the hotline (for Russia it is 8-800-555-33-55) and give this code.
- Expensive. Most of the manufacturer's models have a higher price compared to the products of domestic and Chinese competitors. This is especially true for those profiles that are produced directly in Germany. However, quality products with a 60-year warranty cannot cost the same as cheap, low-grade products that will have to be replaced every 10 years.
- Deviation from norms. Not all of the company’s models in terms of outer wall thickness comply with existing international standards and Russian GOST 30674-99, according to which this parameter should not be lower than 3 mm. In some Rehau economy class models, the wall thickness is 2.8 mm. A deviation from the norm of 0.3, even if insignificant, affects the strength of the product, although at the same time it can significantly reduce its cost (by 10-15%).
Food for thought
Reviews criticizing brand products do not always give an objective picture. Many users who complain about the poor quality of manufacturing and installation of products do not always indicate the name of the company with which the contract was concluded. But it’s one thing if Grunder plastic windows are manufactured in the official representative office of the brand, and quite another thing when we are talking about a third-party company that uses materials and components purchased from the parent company.
For erroneous measurement results, poor installation, and damage caused by improperly functioning equipment or unsatisfactory training of operating personnel, it is not the manufacturers of plastic windows, but the direct performers of the work who are responsible. They are in demand. Therefore, before placing an order, study reviews not only about the Grunder brand, but also about the company with which you intend to enter into an agreement.
