Double seal systems are fitted with two sealing levels. The outer weather seal is inside the frame leg, the inner inside the sash leg. This includes the latest outward opening windows for the UK market including the impressive flush sash.
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 in these tilt and turn windows.
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.
