Promaseal IBS is a fire resistant, flexible foam strip which, when placed in joints and around service penetrations in floors and walls, will maintain the fire resistance of the separating element. In most instances the addition of Promaseal-A Acrylic Sealant is necessary. On some occasions a non fire resistant sealant can be applied.
Promaseal IBS is a factory made product and can be easily verified as being installed in the correct manner. Generally used in lieu of a fire resistant sealant where the specifying authority or certifying body is concerned that the correct depths of sealant or the correct type sealant may not be applied by the contractor.
Promaseal IBS accommodates movement in building services, e.g. the expansion or contraction of metal pipes, while maintaining the integrity of the penetration. It can be used for external wall joints in conjunction with an exterior grade sealant. Promaseal IBS is not designed for use in control joints that are designed to accommodate high or ongoing movement.
