Opis
PU - high performance insulation (0.024 W/(mK)) betweeen two thin coated chipboard panels. 6-point windowframe-locking with circumferential TPE-gasket. Metal-fittings mounted at the hatch box of chipboard. In order to reduce the thermal bridge of the installation, a polystyrene-particle foam granulate (0.033 W/(mK)) is inserted in the joint.
