Curtain Walling is a non-load bearing glazing system which is generally hung on a buildings structure (hence the curtain reference), but can also be dead loaded. Curtain walling forms an integral part of a buildings envelope and there are a number of factors that must be taken into account during its design including; weather tightness (air permeability, water tightness, wind resistance), acoustic requirements, thermal performance, solar shading, and ventilation. Curtain walling is usually characterised by a square or rectangular grid of mullions and transoms, however designs can be further enhanced to incorporate facets, curves and sloped roofs, Curtain wall facades can also incorporate a variety of inserts including; Windows (parallel opening vents, concealed vents, tilt & turn, pivots, top/side hung), photo voltaic panels and Doors. The curtain wall facades aesthetic appearance can be manipulated to offer a flush appearance with the exclusion of face caps (SSG), or can be given enhanced vertical or horizontal emphasis using a Trame/Aerofoil face cap.
