This Air Transfer Grill is designed to allow air to be circulated throughout the building. In the event of a fire, the Air Transfer Grill will close and provide a barrier to restrict the passage of hot gasses. This happens once the intumescent material within the grille reaches the required temperature, it will expand to form a seal in order to protect against hot smoke and fire. A Matching Face plate can be found in the related products section below.
