It expands rapidly under heat, sealing ventilation gaps to prevent flame and smoke from spreading through wall cavities. At just 4mm thick and measuring 1 Meter in length at 35x1000mm, it fits neatly into narrow spaces. The barrier features fire rated intumescent (swells when exposed to heat) materials, meeting stringent UK fire regulations.
