Intumescent Fire Grilles

Fire grilles look just like ordinary ventilation grilles, but can stop air from flowing into a fire by self-sealing as the temperature rises. Every intumescent grille contains a moisture-resistant intumescent core held in a galvanised steel frame for security and long-lasting use. These grilles also have a 6mm vermin proof mesh fitted to both faces, so unwelcome visitors can't get in!

Our fire-resisting grilles can be easily fitted in solid timber fire doors & solid block walls, and come in a variety of sizes and shapes. You can also combine our straight-sided grilles in a variety of ways to cover larger apertures, by fixing grilles in a space with steel straps. Properly fixed, our grilles can provide up to 60 minutes of fire protection.

If air transfer is required but fire protection is not, our range of air transfer plates do the job nicely, made from 20swg mild steel and available in a range of shapes and sizes.
