Aluminium thermal break window
The 77 IS series is the evolution of 77IW, created in order to meet the demands of a minimalist modern market.
Sash is hidden by the frame, allowing for the reduction of the visual impact of aluminum and the increase of the brightness of the interior.
These systems have high thermal insulation, which is obtained through the use of polyamide alveolar bars of 39 mm and reinforced by the insertion of special insulating strips. The solution allows for the reduction of convective motions inside the cavity of the profiles and gives performance values thermal acoustic certificates of considerable value.
It is characterized by sectional profiles from 77mm frame to 87 mm sashes and provides customers with the most demanding solutions and better performance in the AluK range.
