Wooden and aluminium

Combination of the beauty of wood and indestructible properties of aluminium

Aluminium overlays are mounted on the external side of woodwork only. Owing to this solution, we can enjoy the beauty and warmth of wood staying at home. The external structure is resistant to any atmospheric conditions, including wind, water and even high salinity in the sea belt areas.

Unlimited design opportunities

We offer a wide range of shapes of aluminium overlays, their colours and even structures. Aluminium sections can imitate natural wood or have unique hues. There are numerous sections ranging from minimalistic, through slightly rounded to styled milling cutters in Retro windows. Owing to this selection, customers may match appearance of aluminium and wood structure to every design of a building.

Exceptional durability

Aluminium sections are anodised and powder painted. This eliminates necessary maintenance and painting after several years of use. A longer guarantee period is granted for aluminium and wooden windows.
