COto Terrace and Balcony doors are made of a wooden frame with composite material and aluminum claddings on the outside. Terrace & Balcony doors can be used in all type of buildings: private houses, apartment houses, as well as public and office buildings with a wide range of architectural, functional and visual requirements.
Terrace & Balcony doors include an indestructible composite material, which breaks the cold bridge, minimizes heat loss and provides higher temperatures around the edges of the glass. In addition, the risk of internal condensation is greatly minimized.

Even if moisture gets underneath the sash, it cannot damage the window, thanks to the composite part.
