Fire resisting compartments are created to contain fire and smoke from spreading within building structures. However, the principle of compartmentation can also present a parallel threat as most concealed cavities between fire resisting walls and floors are interlinked.

Such gaps are typically at service penetrations through walls and floors but would also include gaps left for structural movement and gaps left due to poor workmanship.

The development of effective solutions to seal gaps at service penetrations has increased over the past few years and Promat has become a world leader  in  supplying
