Window & residential door systems 76 mm systems

TROCAL offers many 76 mm variants for its double seal, centre seal, and residential door systems of PVC-U.

  • Double seal

    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

    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

    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.
