Top quality at the best price

Looking for the perfect premium windows for your home? GM PLAST Window and Door Factory, with over 25 years of experience, offers the highest quality windows on the market, at the most competitive prices. As a window manufacturer, we care about maximum comfort, security and modern design that fits perfectly in any type of home. Our products are not only aesthetically pleasing, but also functional.

Our windows are 7-chamber systems with three gaskets including a centre gasket with an installation depth of 88 mm, which guarantees excellent thermal and acoustic insulation. The centre seal used is an innovative solution that contributes to excellent thermal and acoustic performance. Can be used for passive houses according to ift-Richtlinie WA-15/2.

Our windows use the renowned German Kömmerling profiles, which have a history of over 100 years. This is a guarantee not only of prestige, but also of the highest quality workmanship. Our products are equipped with branded Roto NX hardware with microventilation included in the hinge and burglary protection (RC 2 or RC 3).

In addition, our windows are eco-friendly with lead-free profiles. Excellent value for money, easy care and maintenance, fast production and aesthetically pleasing design make our windows an excellent choice for anyone who values durability and comfort.

With thermal insulation at Uw=0.72 W/(m²K), our windows are energy efficient, saving on heating costs. In addition, sound insulation at 35 db improves the quality of life, guaranteeing peaceful sleep and living comfort.

Our products offer simple and professional installation thanks to a wide range of additional profiles, and the micro-ventilation integrated as standard in the hinge eliminates the need for additional elements on the frame, which increases living comfort. Long service life and ease of use are features that distinguish our top quality windows.
