Gives recommendations for design, properties and maintenance of sloping glass and plastics glazing sheet materials in overhead situations in the envelope and interiors of buildings.

This part of Bs 5516 gives recommendations for design, properties and maintenance of sloping glass and plastics glazing sheet materials in overhead situations in the envelope and interiors of buildings. It includes those situations where the sloping glazing extends down to floor level. These recommendations apply only when the glass is installed in an appropriate glazing system. These recommendations do not apply to: vertical glazing (see BS 6262); glazing for commercial greenhouses (see BS 5502-21); glazing for domestic greenhouses; sloping glazing which is to be used as a walking surface (see Bs 5516-3); profiled plastics sheets. NOTE There are occasions, as with some curved glazing, where parts of a pane might be vertical, while other parts might be sloping. In this case, attention is drawn to both BS 6262 and BS 5516. Requirements for standards of workmanship for glazing have been published separately as BS 8000-7 and, therefore, this subject is not within the scope of this standard. Since the correct selection of materials to be used in glazing for buildings depends on many factors, attention is drawn to the recommendations in the other parts of this standard.
