FyreBOX Cast-In


Trafalgar FyreBOX Cast-In is a simple multi-service passive fire penetration system that can be cast directly into the floor slabs of a building that will prevent the spread of fire through service penetrations whilst reducing the footprint needed for riser shafts and cupboards.

The FyreBOX Cast-In is an intumescent lined system designed to prevent the spread of fire through service penetrations. Think of FyreBOX Cast-In as a fire-rated hole, and as a fire takes hold the intumescent material expands to close off the penetration, forming a tight seal around the services and crushing off plastic pipes and pipe insulation. Intumescent foam plugs are also fitted, giving the FyreBOX superior reliability and acoustic properties, and the ability to allow for adds, moves and changes.

The FyreBOX Range has been tested to AS1530.4-2014 for a range of mixed services and is one of the most fire tested products in the world with industry-leading FRLs of up to -/240/240 (system specific).
