  • Double seal

    Double seal

    A double seal system is generally understood to be a window system with two sealing levels. The window is sealed with an outer and an inner sealing level at the extended leg.

  • Centre seal

    Centre seal

    In the centre seal system, the outer, and hence more important sealing level is in the middle of the profile. KBE normally offers the centre seal systems with only three seals, for a further enhancement of thermal insulation properties.
