Description
Intumescent Movement Joint is a highly compressible strip formed by laminating fire retardant foam to a graphite based intumescent polymer. The material 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 table).

The material is simply compressed by hand and is then pushed into the gap. Adjacent pieces of the product are tightly 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.

Intumescent Expansion Joint is suitable for use in:

• Blockwork cavities
• Expansion joints
• Structural joints
