Xpanfoam is made from an open-cell fire retardant foam, which is then coated both sides with an expandable graphite intumescent sealant,

containing special binders which maintain complete flexibility. The material is non-toxic and installers need no special protective clothing for installation work

Please refer to the table in the technical pdf download which shows a straightforward way to fire-stop movement joints with Xpanfoam. To identify the depth of Xpanfoam required for any application, cross reference the width of joint with the integrity to be maintained.

For example: if the requirement is 20mm joint with a two hour rating, specify Xpanfoam 20mm joint x 2 hours.

The chart represents worst-case scenarios. Where depth of fill is in excess of customer requirements (ie 30mm in the above example) our experts will be pleased to advise on the precise volume needed in specific instances.

Xpanfoam functions as a filler for movement joints, and is completely unaffected by normal environmental conditions or atmospheric moisture. At the designed temperature, the intumescent coating begins to expand on the fire side of the joint. During this reaction, the fire resistant foam gradually compresses and is replaced by the expanding mass of intumescent graphite. Thus fire is prevented from penetrating rapidly into the joint.

Independent fire resistance tests to BS 476: Part 20: 1987 have proved Xpanfoam’s integrity for periods up to four hours. These cover pipe penetrations, cable tray assemblies and apertures in blockwork ranging from 20mm to 100mm. Report data is available on request.
