MasterLine 10

Window system for low-energy buildings
Top quality without compromise

A window system with energy efficiency in mind

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

The MasterLine 10 window range is truly unique in its versatility: windows that open inward, a full range of profiles and frames, connecting profiles for sliding and curtain wall systems, and the design freedom offered by the Renaissance and Deco profile design variants. Windows have Passive House passive building certification

The MasterLine 10 series uses many of the elements already known from the MasterLine 8 system: corner joints, glazing seals and the same central seal allow identical performance, production efficiency and durability.

All these properties make MasterLine 10 an ideal solution for residential and public buildings.
