High insulation window and door system

Global Homez System® 77 is a high insulation window and door system that meets elevated requirements regarding thermal insulation, stability and security. The system’s HI+ variant achieves Uf values down to 1.2 W/m2K. The Uf value of a frame/vent section with 115 mm visible width is 1.7 W/m2K.

GH 77 is available in a variety of aesthetic styles to match the current trends whilst offering all types of both inward and outward opening windows and doors. An additional asset is a possibility to combine this system with Ventalis®.

The system’s performance regarding acoustics, water- and air tightness, but also for specific applications like Bullet – and Fire Resistance, meets the most severe European standards. Moreover, GH 77 is available in different burglar resistance levels (RC2 & RC3) making it an extremely secure system.
