A curtain wall is defined as thin, usually aluminum-framed wall, containing in-fills of glass, metal panels, or thin stone. The framing is attached to the building structure and does not carry the floor or roof loads of the building. The wind and gravity loads of the curtain wall are transferred to the building structure, typically at the floor line.
There are a wide range of possible infill panels for curtain wall systems, including:
Vision glass (which may be double or triple glazed, may include low-e coatings, reflective coatings and so on).
Spandrel (non-vision) glass.
Aluminium or other metals.
Stone or brick veneer.
Fibre-reinforced plastic (FRP).
Louvres or vents.
