Intumescent Sealants & Fire Rated Foam

Intumescent Sealants for Joints, Gaps and Penetrations

Intumescent sealants are commonly used where a flexible, neat, and durable fire-stopping solution is required. They are suitable for linear joints, movement joints, and service penetrations where ongoing movement may occur. Once cured, these sealants remain flexible while continuing to provide fire resistance if exposed to heat.

Typical applications include sealing around pipes, cables, ducts, window frames, and construction joints in both new builds and refurbishment projects. Many intumescent sealants also offer additional benefits such as acoustic sealing and smoke control, supporting overall building performance.

Fire Rated Foam for Rapid and Effective Void Filling

Fire rated expanding foam is ideal for filling larger or irregular gaps quickly and efficiently. It is widely used around door and window frames, service penetrations, and structural openings where speed of installation is essential. Once cured, fire rated foam can be trimmed and finished to provide a clean and compliant seal.

When installed in accordance with tested systems, fire rated foam helps to maintain fire resistance for a specified period, supporting compliance with fire safety requirements while also offering thermal and acoustic insulation properties.
