PROMASEAL® Bulkhead Sealer System BHSB is made using high density mineral wool that is coated with an ablative coating. The coated mineral wool remains in-situ during a fire situation and forms a barrier against the passage of flame, smoke and toxic gases.
The system is the simplest of all fire stopping products to install. It is also one of, if not the most economical product to use. It can be installed in both concrete/masonry floors and walls (with an equal or greater fire resistance level) and has been tested up to 120 minutes with various penetrating services.
