WICTEC 50 EL is a unitised version of the WICTEC 50 stick system. This range combines the advantages of the stick system structure with the assembly benefits of unitised curtain walling and creates extremely narrow sight lines of only 50 or 65 mm. The external profiles are mitre cut, achieving a particularly elegant “picture frame” appearance. Where there are stringent requirements pertaining to thermal insulation, WICTEC 50 EL offers the appropriate solution.

System technology

  • WICTEC 50 EL is a basic unitised system and can be adapted individually to meet specific project requirements
  • The complete units are produced in the workshop, avoiding the influence of weather conditions and assuring a constantly high level of quality
  • Fast, efficient and projectable assembly on site
  • Aluminium profiles using mullion-transom technology, with insulating profiles that provide a high level of thermal insulation
  • Narrow sight lines for maximum transparency
  • Mullions and transoms have the same profile depth
  • Efficient thermal performance, up to Uf = 1.4 W/(m²K)
  • Reliable corner connection with systemised brackets
  • Fast and easy installation on site using a dedicated anchor system
