Firestop Intumescent Strip Fire Only - White

Intumescent door seals are designed to close the gap between the fire door and frame in the event of a fire thereby preventing the spread of smoke and hot gasses. Once installed the seals can lay dormant for many years only activating when exposed to the rising temperatures and pressures in a fire situation.

The high performance intumescent core contains intercalated graphite which in the event of a fire expands multi directionally up to 10-15 times its original size sealing the gap and holding the fire door in place. combined intumescent fire and smoke seal provides additional cold smoke protection sealing off the gap around the door and providing a permanent seal to the passage of smoke.
