AC20-OR window

AC20 OR Wood-aluminium window


The wood aluminium AC 20 OR system represents the classic in our window portfolio. Whether it’s an office, residential building or school the sharp-edged, offset profile geometry on the outside transforms your building into a real eye-catcher.

Give your windows a unique, aesthetic highlight by implementing the aluminium frames on the outside with welded corner joints, thus generating a uniform and seamless surface that will give your windows that special something.

All known constructions of a window or different opening types (tilt-turn, awning, casement, fixed, hopper windows), as well as individual window shapes (angled windows, round, segmental or pointed arches), can be created with the AC 20 OR effortlessly.

Fully concealed hardware? This is no problem for our factory The hardware disappears completely into the window frame and can be used with particularly heavy window sashes.

Hidden millings in the aluminium frame profiles provide controlled and indirect drainage and keep incoming water away from the construction. Due to its durable, classic appearance and reliable, technical quality, the AC 20 OR has become an indispensable window system in sustainable architecture The interplay of the energy-efficient laminated timber frame on the inside and the weather-resistant aluminium cladding on the outside fulfils the Zeitgeist of sustainable building 101.

Create your own space to feel good with the incomparable warmth of our types of wood.
