  • All sills and sashes are composed of two aluminum sections with polyamide thermal barriers, which are assembled through laminated-crimping process. This offers increased rigidity and a perfect seal of the sections.
  • Sills available in 3 depths:
    • 150mm (6”) – 8560
    • 100mm (4”) - 8540
    • 75mm (3”) – 8530

  • Product conceived as per rain screen principle with three rows of weather stripping along the perimeter.
  • Air/water barrier system along the perimeter of the sealed units eliminating rebate joints often the cause of important deficiencies.
  • Euro groove design allowing the use of all European hardware.
  • Choice of square or round glass retaining snap-on mouldings in either horizontal or vertical position.
  • Dry gaskets (dual density coextrusion) eliminating polyisobutilic gaskets that lose their properties with time, not considering the mess they create.
