The energy-efficient high-performance windows with the turn&tiltµ-ventilation opening.
Sizes start from 480 X 480mm and go to 1500 X 1500mm. If needed larger sizes are possible with a limit guarantee meaning in practice the sash must be supported while opening.
Also only tilt ventilation allows the size to be considerably larger.
The fixed frame version is starting from 400 X 450mm going all the way to the 6m2 size with colored frames and 8m2 with white frame.
