Designed squared-edged window frame available exclusively with the classic white UPVC or with an aluminium clad attachment which highlights reduced architecture. Three-sided rendering of the frame fulfils your dreams of almost frameless glass architecture. I-tech glazing, all-round fixing of the glass pane ensures better stability, thermal insulation and security.

The thermal insulation of a window depends on the frame material, the glazing and the impermeability. The parameter is the U value – the lower the figure, the better the thermal insulation.
The soundproofing of a window depends on the frame material, the glazing and the joint permeability. The parameter is the dB value – the tighter a window closes, the better the insulation performance.
|U w =||Thermal insulation of the window acc. to EN 10077-1 (calculated) or acc. to EN 12567-1 (tested) (is stated in watts per square metre kelvin = W/m2K); the following tables state this value per Internorm window system – with stainless alu or ISO spafers respectively|
|U g =||Thermal insulation of the respective glazing|
|R w =||Soundproofing of the window acc. to DIN EN 20140-3 (stated in decibel = dB)|
