Passive house curtain wall

A passive house does not require an active heating system and therefore relies heavily on the thermal insulation and air-tightness of the façade. Based on the standard series, WICTEC 50 is certified for aluminium/glass façades suitable for passive houses at minimal additional cost. The thermal insulation is improved to passivehouse quality with a Uf value of 0.74 W/(m²K) when using triple glazing and an easy-to-install thermal break profile.

Technical Performance

System width: 50 mm
Basic system: WICTEC 50
Thermal insulation: Uf= 0,74 W/(m²K)
Infill thickness: up to 51 mm
Glass weight: up to 5.6 kN
Polygon façade: up to ±5°


System technology:

  • Extension to WICTEC 50 with optimised thermal insulation
  • Certified by the ift Rosenheim as a passive house component according to the ift guidance paper RI WA 15/1, with a Ucw value of 0.7 W/(m²K)
  • Triplex glass construction suitable for passive houses, infill thickness from 45 mm to 51 mm
  • Thermal break profile made of elastomer foam for posterior installation
  • System construction identical to standard WICTEC 50
  • Individual design thanks to a wide range of profile geometries for the structural and glazing profiles
  • Reliable glass load transmission (up to 5.6 kN), with adapted transom-joint technology
  • Overlapping and secure drainage at the cross point, without mechanical mullion processing, ensures tried-and-tested impermeability
  • Filigree look without any change in appearance to the inner mullion and transom gaskets
  • Broad selection of profiles enables economic adaptation to structural requirements, with the additional option of internal reinforcement
