FAQs about Fire Rated Ventilation Grille
1、Where are fire rated ventilation grilles typically used?
- They are commonly installed in:
- Fire-rated doors
- Plant rooms and service shafts
- Electrical rooms and data centers
- Commercial and industrial buildings
2、How do fire rated ventilation grilles work?
Under normal conditions, the grille allows air transfer between spaces. In the event of a fire, the intumescent core expands rapidly , sealing the grille openings and preventing the spread of flames and hot gases.
3、How do I select the right fire grille for my project?
- Required fire rating (FD30 / FD60 / FD120)
- Airflow requirement (free area)
- Opening size and door thickness
- Installation location (door or wall)
