For applications benefiting from small construction depths, there are a double seal and a centre seal system available.
Window & residential door systems : 70 mm system
Double seal systems are fitted with two sealing levels. The outer weather seal is inside the frame leg, the inner inside the sash leg.
In addition to the outer and inner weather seal, centre seal systems are also fitted with a third, centre sealing level. This contributes to enhanced thermal and sound insulation values.
KÖMMERLING residential door systems come in both inward and outward opening versions. In addition to textured glazing, design elements can also take the form of prefabricated panels and modern intersash residential door panelling.
