Fire Sealants

Fire sealants are designed to help protect buildings by sealing gaps and joints where fire, smoke and gases could spread. Suitable for both domestic and commercial installations, they play an important role in meeting fire safety and building regulations across a wide range of construction and renovation projects. Commonly used in walls, floors and service penetrations, heat-resistant sealants help maintain compartmentation and improve overall fire resistance in a building. They’re designed to stay flexible after curing, allowing for natural movement in building materials without losing performance.

The range includes different formulations to suit the job, including intumescent acrylic sealants that expand under heat and hybrid fire-resistant sealants for more demanding applications. Many options also provide acoustic benefits, helping to reduce sound transfer between rooms, while still delivering a clean, professional finish in white or grey. Choose from popular brands including Everbuild and Bostik.
