wall access hatch / rectangular
DWK,DWF & DWT
The L-shaped door DWK is intended to be built into L-shaped walls. Superb thermo-insulating parameters (U=1.1 W/m²K) along with high air tightness keep heat-loss to a minimum. The L-shaped doors may be installed in right or left opening versions. As standard the door is provided with lining slats.
