The Statutory Instrument is titled ‘The Building (Amendment) Regulations 2018’ and amends Schedule 1 to, the Building Act 1984. This amendment applies to buildings in England only. The requirements of the amendment to Part B of the Building Regulations are detailed in Amendment to the Approved Documents dated November 2018.

A brief summary in relation to Glass, Glazing and Fenestration materials is that there is no change to most materials except where these are used in Window Spandrel Panels and Infill (opaque) panels. Window Spandrel Panels and Infill panels must all meet the requirements of non-combustible, i.e. A1 or A2-s1, d0.

Membranes used as part of the external wall construction should achieve a minimum classification of European Class B-s3, d0.
