Ściana osłonowa is a term used in architecture and construction, referring to a light exterior facade of a building that does not support the roof or other floors. It is a kind of exterior wall that hangs, like a curtain, from the structural frame of the building. Curtain walls are usually made of metal, glass or composite panels and are mainly used in modern office buildings and other large constructions. This technology allows you to create large glazed surfaces, ensuring maximum use of natural light and aesthetic and modern design of the building. Curtain walls also provide thermal and acoustic insulation while being light and allowing for greater design flexibility compared to traditional supporting walls.
