Intumescent means tumour forming. What on earth would you want one of those for in DIY?

Intumescent Materials are used for fire protection. On exposure to fire, the items swell up to form a fire and smoke resisting foam that will block fire spread for anything upto an hour.


Intumescent Products

Door seals

These are strips that go into grooves routed into the sides and top of a door. These are a common sight in large buildings.

They prevent fire spread from room to corridor, or vice versa, and protect occupants in other rooms from the smoke, which can be toxic.

Downlighter hoods

These hoods sit on downlighters fitted in ceilings. These fittings penetrate the plaster fire & smoke barrier, and the intumescent hood restores this layer of protection.


Paint

Flammable surfaces in need of fire protection where no visible bulk would be acceptable can be painted with intuescent paint. It isnt cheap.


Varnish

Woodwork can be painted with clear intumescent varnish to create an invisible fire barrier.
