Systems for wooden windows and French windows

The wood of the IV80 Gutmann Mira-TWT wooden window and French window system is 80 mm wide. The overall width of the frame is 100 mm at the double rebate point. The innovation of this system is that the window and door manufacturer can produce a complete window with a 80×80 mm wood cross-section. Frames, sashes, rails or stiles – all components can be machined to a thickness of 80 mm. All the most common types of openings are possible.

Advantages and distinguishing features of this system

  • 80 mm wood width with drip edgeand aluminium frame threshold
    For the first time, it is possible to produce the 80 mm wide wooden window base frame in a combination of weather bar and aluminium frame L-profile. This makes slim-line constructions possible.
  • High thermal transmittance values
    Thanks to the improved rebate geometry, an excellent Uf value is achieved in the lower part of the frame. This factor, together with the larger glass surface area, results in a low Uw value of the entire window.
  • Optimized proportion of glazed area
    With this system, the glazed area increases in proportion to the total area of the window. This allows more natural light into the room and thus improves visual comfort. The latter feature is especially appreciated in renovations.
  • Optimized geometry for ETICS systems and CNC machining
    With the standard wood width, an Alubank parapet with height of up to 40 mm is possible, which simplifies use in ETICS (External Thermal Insulation Composite Systems). The geometry of the rebate is adapted to CNC clamping technology.weathw
