Passive House Institute - Certificate
Certificate type
Aluminium window and door system.
Designed for all passive house buildings, including residential, commercial and office buildings, university campus buildings, hospitals and all zero energy buildings.
The GVG90 aluminium window and door system has the distinction of being the worlds first monolithic vacuum glass-aluminium alloy window to become a Passive House Institute certified component. The GVG90 known as the "window of the future," because of the impressive thermal insulation co-efficient enabling whole window U-values starting from Uw 0.64 W/m2.K. When combined with Werkman Techs hybrid vacuum units, the window will achieve a sound reduction of 44 dB. Accolades include the GVG90 system winning the prestigious Component Special Award at the 23rd International Passive House Conference.
