Air Transfer Grilles
Air movement in a building is important. Grilles are fitted into walls and some doors; and ductwork to keep fresh air circulating. But wherever air moves, fire and smoke can travel too. In a fire, our intumescent grilles expand to form a solid block that stops fire spreading.
Wherever ventilation is needed through a fire-resisting wall or where ductwork runs through that wall, an intumescent fire damper should be fitted at that point to maintain fire compartmentation. Smoke protection is also vital. We offer a range of intumescent grilles and dampers with an added smoke control shutter: our Talkback system.
