Code of practice for the use of profiled sheet for roof and wall cladding on buildings. | Status: Confirmed, Current

1 Scope This British Standard gives recommendations for the design and construction of external cladding assemblies for roofs and walls of buildings in the UK, using longitudinally profiled sheeting as the external surface, including standing seam. It is not applicable to profiled sheeting used as a supporting substrate, decking, structural liner trays, fully supported profiled sheets, structural composite formations of profiled metal sheeting and concrete, small element cladding or exceptional applications, such as buildings for cold storage. The principal profiled sheeting materials covered by this British Standard are steel, aluminium, fibre cement, bitumen fibre and plastics, including insulated sandwich panel assemblies of profiled sheeting, thermal insulation and linings. In addition to referencing performance recommendations, materials and components identified by other British Standards, advice on other materials and components which are in common use but not covered by other British Standards is also given. This British Standard is intended for use by designers, manufacturers and installers of the roofing products. This British Standard includes profiled metal sheets which conform to the scope of BS EN 14782 but excludes profiled metal sheets used for structural purposes, which come within the scope of the BS EN 1090 series of standards.
