Concealed sash window
The option “Concealed Sash” in the aluminium window System WICLINE evo features a special glazing bead fixed directly in the thermal break zone. As a result the system achieves an extremely slim frame elevation, superior thermal insulation values and a groove-free profile design from outside. The improved ratio between frame and glazing surfaces leads to very good Uw-values, increased light transmissions and panoramic views.
Technical performance
Profile technology:
- High insulation multi-chamber system in symmetric design, quality assured thermal insulator connection
- Patented corner and butt joint connection technology for high rigidity of frames and sashes
- Infill thickness up to 42 mm
- Optionally with integration frame for stick curtain walls
Thermal insulation:
- Uf values: until 1.5 W/(m²K)
- Uw values: until 0.94 W/(m²K) with triple glazing
Sealing concept:
- Voluminous centre gasket with three installation methods
- Circumferential centre gasket, avoiding joints in the corner areas
- Formed corners, avoiding adhesive in the joints
- Corner vulcanised frames
