Fire rated intumescent grille

RCI intumescent grilles have been developed to allow free circulation of air at room temperature in building ventilation systems, while also providing protection against flames, smoke and gases in the event of a fire. When exposed to fire, they swell, covering the openings and forming a physical and thermal barrier.
Tested in accordance with EN 1364-5 and EN 1363-1 standards.
