Casement windows / Skylight 75 TOP

WICLINE 75 TOP is a  highly thermally insulating window system with optimal performance, reliable fabrication and performance figures at passive house levels – combined with the familiar slimline appearance of a 75 mm window system.

Technical performance

Profile technology:

  • Highly thermally insulated multi-chamber system with ETC Intelligence® thermal break zone, which implements window designs with only 75 mm frame depth to pas-sive house standards.
  • Patented corner and butt joint technology for high rigidity of components
  • Infill thicknesses up to 65 mm

Thermal insulation:

  • Uf values 0.79 to 1.3 W/(m²K) for fixed glazed units with external sight lines from 48 to 155 mm
  • Uf values 1.0 to 1.2 W/(m²K) for sash-frame combina-tions with external sight lines from 74 to 142 mm
  • Uw values less than 0.80 W/(m²K)

Sealing concept:

  • Large-volume central seal in three variants:
    - Linear gasket insertion without corner butts
    - With formed corners, no sealing of joints
    - Corner vulcanised frames


  • Concealed single-handed operated fittings, optionally with:
    - face-fixed, coated or anodised in all colours
    - concealed hinges with integrated end position damping, opening angle max. 105°
  • Sash weights:
    - Concealed hinges: up to 160 kg
    - Visible hinges: up to 200 kg
    - On request: up to 300 kg
