Description
Flexible Cavity Barrier for Timber
The flexible cavity barrier for timber is a PVC and foil-clad intumescent strip with self-adhesive backing to adhere to walls. Designed especially for timber frame buildings. High expansion intumescent locks against the external side of the internal wall in a fire without affecting the outer wall. Blue plastic sleeve robust enough to prevent damage by water or pests. Under heat the intumescent creates a fire seal, thus providing full fire protection. Cut the seals to any length using the joint sleeve supplied for sealing off the ends.
Specify the overall cavity size and required ventilation gap when ordering.
Cavity Barriers are pieces of fire-stopping material. They fit within the cavity of a building at each floor horizontally and party wall in a verticle position. The material provides compartmentation. Both the flames and heat cannot be transferred to other compartmental areas. Throughout the life of the building, the Cavity Barrier will remain fixed in place. In the event of a fire, the intumescent material expands and seals off the gaps. Additionally, the horizontal barriers allow for a ventilation gap within the cavity. Subsequently closing when the intumescent expands.
