The plastic window market is one of the most competitive. The most important part of a plastic window is the window profile. It forms the window frame into which the insulated glass unit is inserted. Here are the top manufacturers of PVC profiles for plastic windows in 2025.
9. Brusbox
From its inception, the Bryansk-based company has been committed to import substitution. It acquired production lines from KraussMaffei (currently 28), established supply chains for imported raw materials, and began producing high-quality profiles for plastic windows that meet the most stringent European standards. Some say Brusbox is copying Rehau, especially their renowned Basic line, but we would say: good things shouldn't be hidden, but rather shared! Moreover, Bryansk-made PVC profiles, while offering virtually identical quality, cost 15% less. Brusbox also offers premium lines, as well as windows with increased light transmittance. Brusbox windows are impact-resistant, feature strong seams, resist bending and breaking, and are resistant to cold winters.
8. Proplex
One of the pioneers in the plastic window profile market, Proplex began its existence under the guidance of Austrian window makers. More than 20 years have passed since then, and Proplex has flourished and flourished, currently supplying around seven different window types, each designed for the diverse climates of our very diverse country. Proplex windows are versatile and compatible with any hardware. Quality meets European standards – according to Proplex's technologists, products are inspected at least 20 times from start to finish.
7. Montblanc
The company currently owns one of the largest window profile manufacturing plants. The Moscow-area plant is equipped with state-of-the-art, full-cycle production equipment. The company's products include several dozen profiles, both basic and additional. Montblanc has its own R&D facilities and holds several patents, such as a special frame design that distributes heat evenly across the interior surface. The windows are beautifully designed, with smooth, elegant curves; these give even economy-class windows a distinguished look.
6. KBE
These are among the highest quality plastic windows available. Their key feature is maximum quality for the money spent. Despite their moderate price, KBE spares no expense on innovation – the Germans currently hold 35 patents for window profiles, some of which have been widely distributed across the window market. This company's windows have a good reputation; judging by reviews, any problems that arise are usually due to improper installation procedures. Quality control is extremely strict, and according to the manufacturer, the profile is completely identical to that produced at the company's factory near Berlin.
5. Kaleva
The only company in the best plastic window ratings that operates full-cycle – it manufactures, supplies, and installs its own windows. On the one hand, this is a good thing – it reduces logistics and resale costs, leading to lower prices for the average consumer. On the other hand, not all Kalewa factories are capable of maintaining the quality standards set by the parent company. The company's engineers create their own innovations, such as an original design that not only alerts its owners to the weather outside but also advises them to bring an umbrella if rain is expected. Privateglass is also available, which can be frosted on command (controlled by a remote control, like a TV), protecting those inside from prying eyes.
4. Exprof
The list of the best plastic window manufacturers includes a company that uses imported raw materials (German and Italian), but also develops its own innovations. Exprof's engineers developed a proprietary mixture that allows windows to withstand extreme cold and prevent yellowing under UV rays in the summer. Currently, the company is among the top five largest plastic window manufacturers, and its product range includes more than 74 items.
3. Deceuninck
A rare exception among the German companies flooding the window market, Deceuninck is a Belgian company. One of its key selling points is frost resistance. Their PVC profiles can withstand severe frosts, down to -60°C, making them indispensable for the harsh northeastern regions of the country. Deceuninck profiles are often installed in hospitals and kindergartens due to their completely safe and environmentally friendly nature. These windows boast excellent sound insulation, convenient handles for opening, and secure fit of vents and windows in any position. However, there is a downside: the company is overly packaging, resulting in a significant amount of waste after installation.
2. Century
This plastic window manufacturer is a subsidiary of the international company VEKA AG. For over 20 years, Veka has been installing windows throughout our country. According to unofficial data, German companies hold more than half the market, and Veka is one of the leaders. Naturally, all Veka window profiles meet European standards for both ecology and thermal and acoustic insulation, and have received the German RAL quality mark. The quality of the seals is particularly noteworthy – thanks to a special composition, they do not crack in hot weather or freeze in cold weather. Veka's burglar-resistant windows are particularly well-known – there are no equivalents on the market. The profile is called Veka Softline; in addition to the standard energy-saving material and design, the window engineers added several special features, including reliable vandal-resistant hardware and impact-resistant glass. It can withstand a moderate impact – for example, if someone threw a stone at a first-floor window. If desired, the level of protection can be increased by installing four glasses.
1. Rehau
It's one of the world's leading window profile sellers. According to various estimates, Rehau accounted for approximately 191,000 rubles (3,000 rubles) of the plastic window market. It's said that getting a defective Rehau window is impossible – the company's quality control is so thorough.
