The intumescent trunking sleeve from Astroflame is suitable for penetrations through a wide range of fire partition walls and floors. Available in two sizes, the sleeve can be used with standard uPVC trunking or wire cables passed directly through the sleeve. In the event of a fire, the intumescent material expands to seal the penetration, blocking the passage of smoke and flames.
