AC20-CS energy saving windows

AC20 CS Wood-aluminium window


Its completely concealed sash profile renders the AC 20 CS wood/aluminium window a real architectural highlight The sophisticated technology of the integral system enables an enlarged glass surface of the window, thus increasing the incidence of light and creating an incomparable feel-good atmosphere.

Design your room freely according to your wishes. Like all our wood aluminium windows, the integral system AC 20 CS can also be configured with a wide variety of wood types from regional forests so it can be easily adapted to your interior design.

You are free to decide on the colour of your window whether the wood should be naturally stained on the inside or painted according to RAL colours and which colourful eye-catcher the exterior aluminium cladding should add to the building on the outside.

Be it powder coated according to RAL, NCS, DB colours or a matt metal look via anodising – we make everything possible for you. Invisible millings in the aluminium frame profiles ensure controlled and indirect drainage and keep incoming water away from the construction.

The special feature of our integral systems is the uniform appearance in the external view of fixed glazing and openable elements This design feature of the AC 20 CS system is widely used, especially for metre long window sections in office buildings and schools.

The sophisticated technology of the integral system allows for an enlarged glass surface of the window, thus increasing the incidence of light and creating an incomparable feel-good atmosphere.
