LVH Intumescent Fire Door Grilles

The Lorient LVH Intumescent air transfer grilles are specifically designed for use in fire rated door assemblies where pressure relief or extra ventilation is required.

Providing free airflow at ambient conditions; when exposed to elevated temperatures the intumescent material in the slats expands to create a physical barrier to fire and hot smoke.

Fire tested in accordance with AS1530.4 on most AS1905.1 proprietary fire door types, providing up to 4 hour fire resistance.
