Air movement in a building is important. Stale air is bad for both the building and its occupants. Our intumescent grilles combine air movement with fire protection. In everyday use, air can pass freely through the grilles to allow good ventilation. In a fire, the intumescent expands, fusing the grille into a solid block that stops fire spreading.
