Aluminum clad gemini classic windows

GEMINI aluminum-clad windows are modern constructions combining the beauty of wood and the durability of aluminum.

Aluminum-clad windows are based on three basic profiles: IV 68, 78 and 92mm. Aluminum cladding is placed on the outside to protect wood against adverse weather conditions. The wide range of design and colours of aluminum cladding enable perfect matching of windows to the building facade.

The assembly of the aluminum cladding allows the use of thicker, warmer glass packages (Ug = 0.7-05 W / m2K). Due to this the aluminum -clad windows are highly energy-saving constructions.
