Fire resisting compartments work to prevent fire and smoke spreading within a building. But most hidden cavities are, by nature, interlinked. Most of the gaps are used for services, many through walls and floors. Some are left to allow the structure to flex a little, but others are simply down to poor construction.
In some cases technological openings are future-proofed, so any new services added throughout the life of the building can be accounted for up front, throughout the building’s lifespan. The voids left for future use are treated and sealed using materials like intumescents, cementitious mortars, silicone, firestop pillows, mineral fibres and other fire preventing compounds.
Compressible Intumescent strips allowing up to 50% movement.
Water Resistant Intumescent strips.
Water based Intumescent Sealants for internal application allowing up to 15% movement.
Solvent based Intumescent Sealants for external use.
