TROCAL provides several 88 mm variants for its PVC-U centre seal and residential door systems.
Window & residential door systems : 88 mm systems
TROCAL 88 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.
TROCAL 88 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.
