walchwindow04 - Heat insulation figures
Tested and awarded the highest marks
Outstanding heat insulation properties thanks to the slim frame design and the second external sealing plane with permanently elastic silicone seals.
Heat insulation according to EN ISO 10077-1 and EN 10077-2
The Uw values are considerably improved for larger formats due to the narrow frames and the resulting very low proportion of frame with regard to the overall window size - an advantage which often plays a major role in the property sector.
The excellent insulating properties of the silicone foam glass edge bond (psi = 0.033 W/mK) considerably improve the noise and heat insulation properties.
