Concealded sash 75 TOP

In the concealed sash variant of the WICLINE 75 TOP aluminium window system the glass is held directly in the thermal break zone by a special glazing bead. This gives extremely slim frame profiles which also have excellent insulation values and joint-free external frame sight lines. The improved ratio of frame to glazing proportions enables Uw values to passive house standard, and increased light transmission with panoramic views.

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 standard.
  • Patented corner and butt joint technology for high rigidity of components
  • Infill thicknesses up to 50 mm

Thermal insulation:

  • Uf values 0.97 to 1.3 W/(m²K) for fixed glazed units with external sight lines from 48 to 155 mm
  • Uf values up 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 seal without corner joints
    - With formed corners, no adhesive processing of butts
    - Corner vulcanised frames

Hardware:

  • Concealed single-handed operated fittings, optionally with:
    - surface mounted hinges, coated or anodised in all colours
    - concealed hinges with integrated end position damping, opening angle max. 105°
  • Sash weights:
    - concealed hinges: up to 130 kg
    - Visible hinges: up to 130 kg
  • Sash formats (W x H): up to 1,300 mm x 2,250 mm
  • Optionally with opening limiter

System combinations:

  • WICLINE 75 TOP windows can be combined with WICLINE 75 evo windows, and using integration sash-frames, with current WICTEC curtain walling
