Advantages
  • Outstanding thermal insulation with a volume fraction of 60% of the innovative material used for THERMORIT bars: Uw = 0.77 W/(m²K) / Uf value = ≥ 0,89 W/(m²K)*.
  • 
Real wood cladding on the inside as a decorative element, perfectly suited to the optical appearance of the curtain wall. Wide range of different types of wood.
  • 
One piece coextruded medial gasket with insulating foam percentage.
  • 
Individual design options for the interior outer frame profile by using colour adaptable cover profiles.
  • 
Safe glazing technology in conformity with the standards offering large ventilation spaces and an exterior gasket frame with corner vulcanisation.
  • 
Insulation of the glazing rebate by glazing rebate insulating block with large ventilation spaces and insulation of the hollow profile sections by high thermal insulating insertions.
  • 
Fitting variants:
    – Concealed fitting, thereby invisible parts, low-maintenance.
    – Surface-mounted fitting with enhanced version of the standard corner bearing enables higher sash weights and increased stability.
