Lorient Air Transfer Grille Datasheets

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 air transfer 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 air transfer grille 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.
