Product Description

The circular intumescent fire block will fit 200mm dia spiral ducting

Intumescent Fire Blockers provide protection against the 
spread of fire and hot smoke through doors, walls and ductwork. They differ from regular fire dampers in that they have no moving parts; instead they expand to many times their normal size upon exposure to elevated temperatures indicative of a fire, forming an incombustible mass which seals its aperture, preventing the spread of fire and hot smoke.

- No moving parts therefore low maintenance required
- Slim Design 38mm thick
- Tested in timber doors rated up to 60 minutes
- Tested in walls and ductwork rated up to 120 minutes
