Intumescent block for fire stopping gaps around pipes, cables as well as services. Fixing blocks into walls or floors creates a temporary or permanent fire stopping solution. Clad with foil and intumescent strips, the block expands in a fire, which locks in place to seal the void and furthermore prevents firespread.

Each fire stop intumescent block is 1200mm long, designed with intumescent on either side. The fire stop blocks are also compatible with EW Intumescent Wraps. It’s flexible, soft material is easily cut with a sharp blade to fit into any space where required. Ideal as a fire break under suspended computer floors, or between screen walling and concrete floors. In the event of maintaining services, the blocks can also be easily removed for access of services. Designed with self-adhesive tape to join together and fixate into spaces.

– Great for fire-stopping voids in compartmentalised walls and floors- Easily installed around existing services and can be cut to shape to accommodate new ones

– Can be used in conjunction with intumescent wraps or collars to provide 2 hours protection or more for services passing through walls and floors

– Can be used between screen walling and concrete floors as a firebreak
