KBE 88 also offers a wide range of PVC residential doors supplementing the balcony, terrace, and parallel sliding/tilting versions. They are particularly characterised by their high stability and good thermal insulation, ideal for all standard installation conditions.
KBE System_88mm double seal
The KBE System_88mm is a combined system, i.e. the standard version features two sealing levels and is a so called double seal system. The window is sealed with an outer and an inner sealing level at the extended leg.
