The Casement windows with concealed sash of the Schüco AWS BS.HI+ series are an aluminum solution designed for those who want a modern, minimal and clean aesthetic, without giving up performance. The “block” design with concealed sash minimizes the visible elements from the outside, increasing the glazed surface and enhancing transparency: more natural light inside the rooms and an elegant and contemporary architectural impact.
These systems stand out for their design versatility, adapting easily both to new buildings and renovation projects. Depending on requirements, they can be used as a single window, ribbon window or façade insert element, offering a wide range of configurations and opening types. Beyond design, the aim is to guarantee a high level of living comfort in every season. Thermal and acoustic insulation, the possibility of using triple glazing and the integration of concealed fittings make the window suitable also for more advanced performance-driven projects. In addition, compatibility with TipTronic automation solutions expands application possibilities in residential and commercial contexts, improving operation and functionality.
Within the category, two main variants are available — AWS 65 BS.HI+ and AWS 75 BS.HI+ — which share the same aesthetic and design philosophy, but differ in insulation levels, glazing capacity and overall performance, in order to offer the most suitable solution for the specific project requirements.
