What is Intumescent?

image30

Intumescent material is a thin (normally 0.5mm - 2.0mm thick) protection strip or sheet that is placed between the fire door ironmongery and the door itself, to provide passive fire protection.


Passive fire protection is ONLY activated in the event of a fire and works to seal any gaps created between the door and it's frame (to slow the spread of the fire through the doorway).
