Unitised external cladding The term refers to pre-assembled story height façade systems. The walling envelope consisting of cold formed, light weight steel framing is manufactured off-site. A variety of claddings are available which are fixed to the external envelope. Unitised façade systems are particularly beneficial on large scale housing schemes and commercial projects in terms of construction time (600% faster than wet trades e.g. block-work). The design benefits are bespoke external finishes and a wide range of external façade options. As well as ‘conventional' render brickwork and glass finishes, rain-screen technologies are particularly innovative and offer robust, long-life solutions. These include terracotta tiles, aluminium and enamelled steel cladding, timber and colour photovoltaic systems.
