Air Transfer Grilles
When ventilation is required through a fire door intumescent grilles are able to be installed to keep the integrity of the door intact. They have been vigorously fire tested in accordance to AS1530.4 to achieve a 2 hour fire rating with most proprietary fire doors that compile with AS1905.1.
The Damper will be installed with decorative face-fixed powder coated cover grilles that provide a
clean, neat appearance in standard sizes
