The KÖMMERLING 76 mm double and centre seal systems are ideal for renovations and new construction. Both systems feature steel reinforced European uPVC profiles. Available with double and triple glazing in a number of different profile finishes, the 76 mm systems are the preferred choice for high-quality window and door manufacturers.
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 also feature a third, centre sealing level. This contributes to enhanced thermal and sound insulation values.
