Block windows under passive building standards.

Aluminium windows AWS 90 BS.SI+ represent another block windows with increased thermal insulation. AWS 90 BS.SI+ window system combines aesthetics, modern design and passive building standards in terms of thermal insulation. Heat transfer at the level of Uf= 1.2W/(m²K) along with narrow profiles give the possibility of installation, making window sashes invisible.
