From our Norfolk & Suffolk branch
Join us for this
free, online webinar discussing fire suppression in mass timber construction.
This event is presented by Dale Kinnersley, convenor of RISCAuthority Sprinkler Rules and Suppression & Detection Working Groups. Dale will start with the core presentation for 45-50 minutes before hosting a 10-15 minute Q&A session.
Overview
This session explores the fire safety challenges posed by mass timber construction and presents new research on sprinkler performance and fixings under fire conditions. As exposed CLT and other engineered timber products become more common, traditional sprinkler assumptions no longer ensure effective protection. The session reviews insurance concerns, knowledge gaps, and the need for adapted suppression strategies. It summarises recent PhD research examining sprinkler spray behaviour, ceiling/wall/floor wetting, and the suitability of CUP-type sprinklers for protecting combustible timber surfaces.
Complementary testing on screw fixings in CLT highlights significant strength loss during fire. The findings support updated standards and improved installation methods to enhance the resilience of modern timber buildings.
