Rainscreen and masonry façades are popular building envelope specifications, particularly in high–rise applications. They allow architectural freedom, whilst providing suitable protection against the elements.
However, choosing the best route to compliance, with current fire safety regulatory requirements in Great Britain, requires a clear understanding of the complexities and the common misconceptions that surround the use of insulation in these constructions. The route that best serves the purpose of the building and the needs of stakeholders, whilst producing a well–balanced result, may not always be the most obvious option.
Our technical bulletin on façades and fire safety examines the use of insulation in the façades of buildings with a habitable storey 18 metres, or greater, above ground level in England. It also advises on how to interpret the guidance given in Approved Documents B Volume 2, for meeting the fire safety requirements of the Building Regulations for external fire spread including the most recent Amendment to Approved Document B.
