Fire-resistant grates (custom-made)
COR CFR GRILLE fire-resistant ventilation grilles allow air circulation between compartments and help prevent the spread of flames and smoke in case of fire. Made of intumescent material, they expand at temperatures above 140°C, automatically closing the ventilation openings. They guarantee airflow of up to 80% and can offer fire resistance of 60, 120 or 240 minutes, according to applicable technical documentation.
