High performance 50 mm curtain wall

ConceptWall 50 is a 50 mm stick curtain wall and roof system for projects that need slim sightlines, design flexibility and reliable performance. It supports a wide range of façade geometries and looks, from standard mullion transom grids to structural glazed and slimline variants, with options for roof glazing and combinations of vertical and inclined planes. Highly insulated versions can approach Passive House level performance while still allowing large spans and high glass weights.

The system is engineered for demanding conditions, with low frame Uf values, excellent air, water and wind resistance (up to AE 1950 / RE 1950 / E 2400) and dedicated fire rated and burglar resistant variants. A full range of inward and outward opening elements lets you integrate windows, doors and vents without breaking the façade design, keeping one coherent logic across the envelope.
