KF410 Window profile

You always take the right decision with KF410. The square-edged design of frame and sash matches the design style of home pure. Due to the new I-tec insulation technology, the frame is insulated continuously and thereby thermal insulation is improved considerably.

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.

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)
