TROCAL offers many 76 mm variants for its double seal, centre seal, and residential door systems of PVC-U.
Window & residential door systems : 76 mm systems
-
Double seal
A double seal system is defined by its two sealing levels. Both an internal and external permanently elastic weather seal provides the perfect protection between the sash and window frame.
-
Centre seal
A centre seal system not only has an internal and external weather seal, but also features a third sealing level that is fitted at the centre of the outer frame and is therefore invisible. This safeguards better thermal insulation values.
-
Residential door
In addition to its window and balcony, terrace, sliding, and lift/sliding door systems, TROCAL also offers a wide range of PVC-U residential door variants.
