Sealants & Mastics

Intumescent sealants and mastics are used to seal gaps and service penetrations in fire-resisting walls, floors and partitions. When exposed to heat, the sealant expands to close openings, helping to maintain the fire integrity of the compartment. Our range of intumescent sealants and mastics is suitable for use around pipes, cables, trunking and small movement joints in commercial and residential buildings.
