Intumescent Ventilation Grille
Mcr Silgrill
- Free airflow
Intumescent fire protection ventilation grilles allow free airflow at room temperature through a structural element (e.g., walls and doors). - Effective fire protection
The grilles provide reliable protection in the event of fire. - Expansion under heat
When exposed to fire, the grilles expand under high temperature, forming a layer of non-combustible foam. - Insulation against flames, smoke, and fire gases
The foam layer acts as insulation, preventing the spread of flames, smoke, and fire gases into the non-affected parts of the building.
