A simple structure and great opportunities
The sashes and fixed elements operate on two parallel planes. The sashes slide on fixed elements. This type of structure ensures intuitive and easy operation even for a child, regardless of the window size. In HS windows there is no risk of catching or damage of the window by wind gusts.
Maximum width of a sash is 3.33 m. Using an extended “L” scheme, we can obtain even 13 meters of free space with the window opened as part of one structure.
