IHS BRE Press Fire Performance of External Thermal Insulation for Walls of Multistorey Buildings BR135

Understand the principles and design methodologies for fire performance characteristics of external cladding systems with the third edition of this authoritative BRE guide, fully updated to reflect current materials and technologies. Author: S Colwell and T Baker Publish Date: 3/15/2013 ISBN: 978-1-84806-234-4 Abstract: External cladding systems offer a potential route for fire spread through multistorey buildings. This third edition of BR 135 sets out the principles and design methodologies related to the fire spread performance characteristics of non-loadbearing cladding systems, and provides revised guidance in the light of the growing market for cladding systems and increasing thermal performance requirements. It also updates the guidance on fire performance of currently used materials and technologies.The illustrations and scenarios given are based on typical examples of current practice, but, in view of the rapid changes in designs and materials, the guidance aims to enable designers to understand the parameters relating to fire safety design and construction of external cladding. It also consolidates the fire performance classification systems for full-scale fire tests in BS 8414.
