With the ASS 80 FD.HI folding/sliding door, Schuco offers a unique folding/sliding system, which achieves an Uf value of down to 1.6 W/m²K and a Uw value <1.3 W/m²K. The requirements of EnEV 2009 are therefore fulfilled with ease. The outstanding Uf values are achieved by extending the insulation zone, integrating a centre gasket in the outer frame and using glazing rebate insulation.
