Essential components for fire doors

Intumescent door seals are designed to close the gap between the fire door and frame in the event of a fire, thereby preventing the spread of smoke and hot gasses.

Our range of intumescent fire seals is suitable for use in a variety of fire door applications.

Fire doors help protect lives and property by slowing the spread of fire throughout a building. Intumescent fire seals are a key component in fire doors, used to protect the gaps between the door and frame as well as encasing certain door hardware. Intumescent fire seals help resist fire by expanding during fire conditions to fill gaps and provide a degree
of insulation.

The range consists of several intumescent materials including graphite-based, silicate-based and phosphate-based solutions depending on your technical preference. As well as a choice of material, our products can be chosen with or without a protective PVC casing. Our encased intumescent fire seals can be supplied with integrated brushes and fins for additional smoke and acoustic protection.

Thinner, more flexible intumescent options are available if required.
