This is a very slim window with a construction depth of 74 mm. The rounded edges of sash and frame match design style home soft perfectly. The new 6-chamber frame profile ensures even better thermal insulation. Three continuous gaskets protect the inside area from the wet and improve thermal insulation and sound reduction at the same time.

Glazing systems

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.

Uw 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
Ug Thermal insulation of the respective glazing
Rw Soundproofing of the window acc. to DIN EN 20140-3 (stated in decibel = dB)
