COR CFR GRILLE ventilation grilles are made of a material that expands when exposed to temperatures above 140 °C. Intumescent inserts seal the ventilation openings during a fire, preventing the spread of flames and smoke

APPLICATION:

COR CFR grilles are installed in ventilation openings in walls and floors. The material’s expansion during a fire completely fills the opening, preventing flames and smoke from entering adjacent rooms.
