Popular window systems are copied no less than clothes from famous brands. Developing, implementing and promoting your own is long and expensive - it’s much easier to take advantage of someone else’s success. The real REHAU profile is faked more often than others. BRUSBOX, MONTBLANC, Plafen, ARTEC are similar in appearance and geometry, but these profiles are much cheaper. How to distinguish a copy from the original? Tips from will help you do this yourself.
How to check the authenticity of the Rehau profile on the official REHAU website?
- On the official website of the German concern for the Russian-speaking audience, select the “Check profile” section.
Reconciliation web page on the REHAU website
- Find the article number of the current PVC. This is a combination of letters and numbers of the REHAU brand, containing the profile series code.
Variant of the original marking. The article numbers of systems produced since 2015 contain 7 digits, the first of which is 1. Earlier systems have article numbers of 6 digits.
The placement of articles on the frame profile, sash, impost is indicated by arrows:
Stamping of Rehau articles on the original profile (web page on the REHAU website)
Placement of REHAU symbols on a PVC box. The symbolism is found in the bead groove when the sash is opened.
In a blind window, you will have to remove the glazing bead to view the markings. It is better to dismantle when installing windows. In front of it, specialists remove the glazing bead and remove the double-glazed windows from the sashes. It is very difficult to dismantle the glazing bead in an installed window. Manipulation requires special tools, a qualified craftsman, the profile and glass unit may be damaged.
Sash - the marking located inside the system is visible on the sash after removing the glass package.
Impost (window lintel) - contains a branded stamp, available for viewing after opening the sash and removing the sealing rubber from the impost. You can see the impost markings in a blind window after removing the glass bag and seal. In accordance with the State Standard, a company stamp is placed on the profile at intervals of 1 meter.
Extract from GOST 30673-99 - PVC profiles for window and door blocks
After opening the sash of the 1.4 m high window system, a couple of markings are visible, including partially applied ones. At a window already 1 meter long, the PVC markings may not be visible. It needs to be viewed on the longer side of the window.
- Enter the detected article in the appropriate field.
- Click on the “Define” button. Next, two message options are possible. If the profile is fake, the marking is not from the manufacturer, then the content of the message will be: “Article not found.”

That is, the window is not made of German PVC Rehau. In the case of the original, the message contains the phrase “Your window is made from a profile” and the series number. That is, the Rehau PVC system. Similarly, it will soon be possible to determine the origin of glazing beads, seals, connectors, and other parts on the manufacturer’s website.
Is it possible to fake profile markings?
When checking the Rehau profile, the window owner may have the following question:
Question: Can a profile made “under REHAU” have markings that repeat the REHAU marking?
Answer: Technically yes. In practice, no, because the marking contains the REHAU trademark name, which is protected by patent law.
Neither the manufacturer nor the window seller can change the profile markings.
The method of checking windows from Rehau's profile on the company's official website allows you to 100% verify the authenticity and dispel all doubts.
Developments in technology make it easier and cheaper to create counterfeits of packaging, labels and other attributes of identifying a product and its belonging to a particular brand. Creating mechanisms that allow the buyer to verify the authenticity of a product is an important task for well-known brands. The Rehau profile verification system makes it possible to do this.

How to determine the original by the protective film?
REHAU protective film with a special design helps to identify genuine plastic. On white PVC, REHAU inscriptions are printed on the film inside and outside the profile; on laminated PVC, this has also been available since 2018. If there are such inscriptions, this is a guarantee of high quality surfaces. There are no PVC model names on the film. To verify it, additional information is needed.
It is extremely rare to dare to fake the design of a film to protect plastic. There is not always a protective film on the windows when they are already in use. Therefore, it is safer to rely on a protective system implemented using proprietary markings of parts.

The German company Rehau is today a world leader in the production of polymer products.
Windows from the Rehau profile consist of many elements. This is a box, glazing bead, stand profile and more. Many companies that sell Rehau windows save on these elements; all that remains of a Rehau window is the box. By the way, these elements affect the strength, thermal conductivity, sound and water resistance, environmental friendliness and durability of the entire structure.
Differences between the original REHAU profile and the fake
It is impossible to see what is inside the profile, so we will consider only the obvious signs of the original windows of the German brand visible from the outside.

- Laser marking . It is located at the end of the opening sash - an inscription with its name is engraved on the profile every 25 cm. For example, REHAU Euro Design 60. Cheap copies, similar in thickness and configuration, do not have it.
- Certificate of conformity . It will not be available for a finished window - it is impossible to obtain a certificate for each product with individual sizes. The document is issued separately for the profile, fittings and double-glazed windows. There is a possibility that the seller, having demonstrated one certificate, will ship completely different products. For a real REHAU, the markings on the document and on the end of the sash are identical. The same goes for fittings. This certificate must have a brand name with a hologram, protection in the form of a special mesh and a validity period (no more than 12 months).
- Indication of GOST, batch number and profile series. You can see small markings with this information only before installation. The place where it is applied is the frame and imposts. You can distinguish a fake from an original REHAU profile by the absence of such data.
- Compliance of the product with the declared profile width . For a window made from REHAU Intelio 80, the frame thickness is not 75 or 78, but precisely 80 mm. The manufacturer strictly adheres to the declared values.
- Connecting and additional elements of the same shade with the main profile . This is clearly noticeable when ordering a pair of balconies or windows with extensions.
- Serial number matching . You can check the authenticity of the delivered products by calling the German company’s hotline. Provide the serial number and find out whether this profile is a company product.
- Gray or red REHAU Quality logo . It is placed on the sash. The presence of a sticker nearby indicating the name and contacts of the selling company indicates that the latter is an official representative of the manufacturer.
- Closed sealing circuit . REHAU windows do not have cut seals.
- Only rubber for sealing . The choice in favor of this material is due to its durability, elasticity and adaptation to any temperature.
- Invisibility of seals . You can also distinguish a real REHAU profile from a fake by its invisible seals. They are not conspicuous due to the well-chosen angle of inclination.
- Price . A standard double-hung window equipped in accordance with the manufacturer’s requirements and with a profile from a leading German brand cannot cost 5,000 rubles. These are not budget products at all.
is the official representative. The manufacturer works only with authorized partners. Companies specializing in cheap economy-class products are not one of them. Simply buying such a profile and equipping it with cheap double-glazed windows and fittings will not work. The manufacturer strictly monitors sales of its products and compliance with packaging requirements.
Signs of counterfeiting of already installed Rehau windows
- Rapid depressurization. For the first few months after installing cheap PVC windows, the buyer will most likely have no complaints about the product. Problems with the appearance of condensation, drafts, and heat loss from the room appear when the temperature and humidity levels change both in the room and outside the window.
- The appearance of fungus and mold. Owners quickly pay attention to darkening at the joints of profiles, the connection of a window sill, or the transition to slopes on windows. But problems with the glazing of a balcony or loggia are attributed to the microclimate and are rather blamed on the developer. This is not entirely true. Rehau profiles are designed for use in conditions of high humidity: in swimming pools, kitchens, sauna dressing rooms, gazebos, etc.
- Cracks and drying out of the sealant. It is responsible for the tight fit of the sash to the frame and plays a significant role in ensuring the long service life of other parts and components. Since an incorrectly closed window loads the entire system.
- Problems with fittings. The “scissors” responsible for the transition from the swing to the folding position of the sash can slip the required clutch. As a result, the window will be open at an angle. Poor quality hinges sag quickly and require frequent adjustment. The handle loses its smooth movement.
- Plastic turns yellow over time. The appearance of stains and difficult to wash off natural dirt on the profile is not the norm. Fading of painted, laminated or originally colored profiles is also not the norm.
Advantages and disadvantages of Rehau windows
Rehau windows have the following advantages:
- Wide range of colors. You can make the frames and sashes multi-colored or imitate natural materials, such as wood.
- Resistant to temperature changes. When creating windows, Rehau specialists took into account the fact that their designs must work well in any temperature and weather conditions, so PVC is designed for a range from -50ºС to + 80°С. Not all manufacturers of plastic windows can say the same about their product.
- Good sound insulation. Even the simplest basic model of a Rehau window can save a city dweller from street noise and ensure silence in the house.
- High burglary resistance. Even basic budget window models are provided with good protection: it is almost impossible to break the sash fastening. Also, if desired, you can install additional protection - special mechanisms on the handle or fittings.
- Nice appearance. Rehau window manufacturers care not only about the technical characteristics of their products, but also about the design. The soft rounding of the window bevels is all pleasing to the eye.
- Easy care. All models have a perfectly flat surface, the material itself does not collect dust, so the windows are easy to clean. To do this, you can use water, a neutral detergent and a soft sponge or cloth.
- Variation and variety. Rehau windows are produced in various shapes and sizes, which means that any design idea can be brought to life.
The disadvantages include the high price, but the high European quality of Rehau windows fully justifies their cost.
Choosing accessories
Window sashes can be fixed, rotary or tilt-and-turn, and also have a micro-ventilation function.
The quality of window fittings plays an important role when choosing a product. Locking mechanisms, hinges and handles are under constant load. By skimping on these components, you risk needing repairs in the near future.
Reliable German fittings from the Roto brand, in addition to durability (the estimated number of closing-opening cycles compared to budget options may differ significantly), increases burglary resistance and ease of use.
If we talk about the choice of handles, the Linea Design series from REHAU has an ergonomic shape and can optionally be equipped with a locking mechanism. Think about their convenience, because this is the component you come across every day.
A handle with a lock is especially relevant for children's
As for aesthetics, standard hinges can be replaced with hidden ones (invisible from the outside), and the glass can be decorated with sprockets.

Rehau Blitz
The Rehau Blitz three-chamber profile differs from previous models by its affordable price. The PVC window profile combines an acceptable level of performance in both heat and sound insulation. The low price of the Rehau Blitz window is dictated by the low resistance of its profile to burglary.
Because of this feature, this window model is not entirely suitable for installation in private houses, as well as in apartments located on the first floors of the building. For the rest, purchasing a Rehau Blitz window would be quite appropriate.
Rehau Geneo
Recent technical advances have allowed the company's engineers to widely use the Geneo profile to produce windows of non-standard shapes: round, oval, triangular and even trapezoidal - now plastic windows from Rehau can be anything. This profile specificity is fully used by architects when designing buildings under construction (mainly private sector houses), as well as by designers who bring to life the owners’ ideas for creating an unusual style of room.
However, the advantages of the Rehau Geneo profile are not only the large number of possible shapes. The Geneo double-glazed window, equipped with two chambers, has excellent thermal insulation and is also able to reliably protect the adjacent room from the penetration of extraneous sounds from the street.
Branded fittings installed in the Rehau Geneo window model are responsible for the operation of the sashes in three positions: turning, tilting and turning and tilting. The weight of the Rehau Geneo profile is 2/3 less than the weight of a standard PVC profile. This feature has a beneficial effect both on the installation work and on the load produced by the profile on the fitting mechanisms - their trouble-free service life becomes longer.
Choosing a double-glazed window
A double-glazed window is glass directly that is inserted into the profile. Depending on the number of glasses, a double-glazed window can be single-chamber, double-chamber, and so on. The number of cameras in most cases will be equal to the number of glasses minus one. The exception is triplex - laminated glass.
The value of the chamber width has a direct impact on the quality characteristics of the double-glazed window as a whole and directly correlates with the width of the selected profile. To avoid the spread of the phenomenon of sound resonance, double-glazed windows with asymmetric chambers are installed. This means that the widths of the chambers will not match, resulting in resonance damping. Also, to increase sound insulation, you can install triplex (laminated glass with a polymer film), which will significantly increase acoustic reflectivity.
Double-glazed window with triplex and asymmetric cameras
We recommend choosing energy-saving double-glazed windows. A special silver coating is applied to the inside of the glass and prevents heat from leaving the room in winter and reflects external thermal energy in summer. Comfortable balance.
Operating principle of energy-saving coating
Double-glazed windows can also be armored, sun-protection, tinted or mirrored. Heat saving is achieved by spraying the outer surface of the glass, and also filling the chambers with argon. Thanks to these technologies, heat is perfectly retained indoors.
