Description
Corofil C500X Intumescent Expansion Joint is a highly compressible strip formed by laminating fire retardant foam to a graphite based intumescent polymer.
Corofil C500X Intumescent Expansion Joint is delivered to site in pre-formed sections. The section size depends on the joint size and the fire rating that needs to be achieved (See Fire Rating).
Corofil C500X Intumescent Expansion Joint is simply compressed by hand and is then pushed into the gap. Adjacent pieces of the product are simply butted together. There is no need to use any adhesives or intumescent sealant in conjunction with the product.
In a fire, the graphite based intumescent material swells to form a hard char which prevents the passage of fire and smoke through the joint.
Corofil C500X Intumescent Expansion Joint is suitable for use in:
- Blockwork cavities
- Expansion joints
- Structural joints
- Curtain wall/Concrete slab interfaces
