2025 research
Among the most significant research completed in 2025 was the culmination of a four year programme examining sprinkler protection in mass timber buildings. As engineered timber systems are increasingly adopted as part of modern methods of construction, they bring environmental benefits and construction efficiencies, but also introduce fire behaviours that are not adequately addressed by existing sprinkler design rules.
Traditional sprinkler standards assume non combustible ceilings. They are not designed to control fires involving combustible structural elements overhead, nor to account for the progressive weakening of timber fixings during fire exposure. This creates potential failure modes where pipework or ceiling mounted fixtures could detach and fall while a fire is ongoing. A risk highlighted starkly by incidents such as the Shirley Towers fire in 2010.
Our research explored how fixing strength reduces during fire exposure, how different fixing types perform, and how sprinkler wetting patterns can be optimised to achieve effective ceiling and wall coverage in mass timber buildings. The work provides an evidence base that directly addresses known gaps in current sprinkler rules.
The research has been nominated for an industry award, and this significant contribution to fire science has also formed the basis of a PhD by its lead author, Dale Kinnersley. This research will be incorporated into the LPC Sprinkler Rules (available from the FPA website) and hopefully inform fixing guidance, not just for sprinklers, but for any fixings into timber ceilings.
During 2025, we also delivered a wide range of practical guidance and tools supporting passive fire protection, risk control, business continuity, and security. These included:
- Passive Fire Protection: BDM30 – Elements of construction
- Risk control: RC69 (Wind Turbines), RC70 (Switchgear and Transformers)
- Business continuity: Business Continuity Template (free online); What Does Good Look Like in Business Continuity Management; and a comprehensive guide to running BCM tabletop scenario exercises
- Security: Electronic Call Handling Operations (ECHO), Supply Chain Resilience, and Alarm Transmission Systems guidance
