Window & residential door uPVC systems

76 mm systems

The 76 mm double and centre seal systems are ideal for renovations and new buildings. The small construction depth and the slender profile sight lines offer the best advantages for renovations.

Double Seal

Double seal systems are fitted with two sealing levels. The outer weather seal is inside the frame leg, the inner inside the sash leg.

Centre Seal

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.
