FSi Promat highlights key steps for selecting tested passive fire protection systems for lightweight modern building façades.
Choosing the correct fire stopping systems for lightweight modern façades remains a complex challenge for installers and specifiers. Passive fire protection manufacturer FSi Promat, via fire stop manager Paul Nash, has set out a simplified framework for selecting passive fire protection designed to prevent fire spread through exterior wall cavities and lightweight structural systems.
Building safety regulations have tightened significantly, placing strict accountability on installers to ensure all passive fire barriers match tested configurations. Modern lightweight façades often present complex movement joints and varying cavity sizes. Using mismatched or untested fire cavity barriers, sealants, and fire-rated wraps risks failing building control inspections and creates life-safety hazards.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for? For dryliners, joiners, and façade installers buying fire-stop mastic, intumescent seals, and insulation from trade merchants like Travis Perkins, Wickes, or B&Q, it means specification must take priority over initial cost. Installers must avoid buying piecemeal components from different manufacturers to save money. Buying complete, third-party tested system kits from a single manufacturer ensures full regulatory compliance and avoids costly retrofits during building control sign-offs. Always check manufacturer data sheets to match the exact sealant or barrier product to the substrate and cavity width on site.
