The word ‘intumescent’ refers to substances that expand and decrease in density on exposure to heat. This behaviour can be used as a coating to protect materials from damage or failure during a fire, or can be used to seal gaps to prevent the spread of fire and smoke.

An Intumescent fire and smoke seal is defined in [https://www.firecode.org.uk/ The code of practice: Hardware for fire and escape doors, Issue 5], (published by DHF and GAI in November 2024) as 'A combined seal designed to enhance the performance of a fire & smoke door assembly, generally by virtue of an intumescent core in the seal profile along with a flexible smoke sealing element (fin or brush).
