Defines requirements for the design, fabrication and performance of windows and glazed doorsets made from PVC-U extruded hollow profiles.

This British Standard specifies requirements for the design, fabrication and performance of windows and glazed doorsets made from PVC-U extruded hollow profiles. This British Standard applies to windows and doorsets manufactured from PVC-U hollow profiles incorporating fusion welded corner joints. It applies to windows and doors fabricated into frames in a factory, to be installed vertically (within 15°) into the external face of buildings, as single or multi-light units, in coupled assemblies when appropriate, of the following types: windows: hinged: side-hung (open in or out), top-hung (open out), bottom-hung (open in), tilt and turn or turn before tilt; projecting: side-hung (open in or open out) and top-hung (open out or reversible); pivoted: horizontal and vertical (hung centrally or off-centre) including reversible; sliding: horizontal and vertical; side-hung: fully reversible; fixed light; doors: single leaf single-swing doors with or without side lights and top panels; double leaf single-swing doors with or without side lights and top panels. It is applicable to assemblies in which any frame member is not longer than 3m. It does not apply to curtain walls that span across horizontal structural members of floors but is applicable to windows within a curtain walling system. It is applicable to assemblies up to the point of installation. NOTE Guidance on the evaluation of conformity is given in AnnexA. Guidance on durability and recycling is given in AnnexB.
