A window system with energy efficiency in mind

MasterLine 10 windows have been designed in line with contemporary and future trends: energy efficiency, maximum daylight access, top performance and security (burglary protection class 3).

The MasterLine 10 window range is truly unique in its versatility: windows that open inwards, a full range of profiles and frames, connecting profiles for sliding and curtain wall systems, and the design freedom offered by the Renesans and Deco profile design variants. The windows are Passive House certified so they are suitable for passive houses.

The MasterLine 10 series uses many elements already familiar from the MasterLine 8 system: corner joints, glazing seals and the same central seal. This makes it possible to achieve identical performance, production efficiency and durability.

All these properties make this system undoubtedly the ideal solution for residential and public buildings.

Modern, sophisticated, robust and easy to use - these are without doubt our aluminium windows. GM PLAST is one of the leading manufacturers and suppliers of high quality aluminium windows in Poland. We offer a wide range of windows that are designed to provide a minimalist and ultra-modern style.
