It is an inward-opening system with thermal break, designed to be fitted with perimeter hardware featuring multi-point locking.
Albio 129C Advanced is the only system with a sash depth of 78.3 mm offering superior thermal insulation properties, with Uf = 1.48 W/(m²K) and Uw = 1.4 W/(m²K) when using glazing with a Ug value of 1.0 W/(m²K), thanks to the use of special polyamides for the thermal break.
The system’s straight-line design provides a minimalist look and enhanced aesthetics. Additionally, there is the option to use a frame that is flush with the sashes not only on the exterior but also on the interior side.
