Promaseal IBS Rod (IBS)

IBS foam strip is a flexible fire resistant backing rod for sealing joints and gaps plus ideal at sealing various services that require movement. This product is ideal for use around pipes, cables and ducts through masonry, plaster walls or floors and movement joints eg as a fire resistant wrap around pipes that require movement due to hot and cold contractions. IBS foam strip is coloured for ease of identification and is easy to install by compressing and inserting it into the joint or gap. The addition of sealant is optional. IBS foam strip is of particular use where the size of the opening around services would result in the slumping of a sealant. It forms a slip joint at the service penetration so that when services move, the integrity of the opening is maintained. This is unlike many solid barriers where cracking can occur due to movement.
