Superior design, quality and performance
Our ultra thin wooden aluminium windows are guaranteed to stand out with their stunning contemporary design. Designed and handmade by Italian craftsmen, the lightweight and durable frames can make up large openable sashes while maintaining a frame as thin as 3.7 cm.
Our luxury range of slim-frame wooden aluminium windows by far outperform aluminium and composite windows with a similar form factor and boast a significantly better energy efficiency, thanks to the warm timber frame.
