A specially formulated gypsum based product intended to provide a fire rated seal around service penetrations in fire rated walls and floors. Supplied as a powder to be mixed with water, the resulting compound is load bearing and provides a smoke seal and good acoustic insulation.
The compound is trowelled or poured around the service penetration and can be used in floors and walls.
Existing Firestop Compound installations can be easily drilled or sawn to allow the provision of additional or replacement services and subsequently re-sealed. Recommended minimum clearance between services and surrounding structure: 50 mm, or half the diameter, whichever is greater.
