Approved Document B of the Building Regulations covers fire safety matters within and around buildings. Published in two volumes, Volume 1 deals solely with dwellings, including blocks of flats, while this volume – Volume 2 – deals with all other types of building cover by the Building Regulations.
The aim of each volume is to set out the guidelines that need to be followed in order to prevent the spread of fire over linings, such as walls and ceilings. Each volume also states what materials can be used and what British Standards each should conform to, to ensure that they provide the required level of protection.
This new, revised edition of Approved Document B incorporates the May 2020 amendment booklet which takes effect on 26 November 2020.
