Intumescent Ventilation Grille
  • 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.
