Publisher's Synopsis
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 and comes into effect on 30 August 2019.

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.
