AWS 75.SI+

The Schüco AWS 75.SI+ window was launched in 2005 and since then has been improved in terms of compliance with statutory requirements and thermal insulation. In AWS 75.SI+ aluminium windows, the heat transfer coefficient has been reduced by 0.1 W/(m²K) to Uf = 1.2 W/(m²K), thus eliminating the installation depth requirement and introducing the product into serial production.

We replaced the assembly system with a central seal. With the new generation of Schüco AvanTec fittings, the time required for window installation is significantly reduced.

  • Central seal and glazing frame insulation
  • Application of profiles, resulting in reduced assembly time
