Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

The main purpose of the edge of slab fire protection is to prevent fire spreading between linear gaps and the building substrate. The integrity requirements for cavity barriers of such form is different than the one for penetrations. In the event of fire such barriers should act as a closure. Often such barriers are concealed to the naked eye and are in hidden areas such as bulkhead spaces.
