Sealant helps minimise sound transfer

The firestop sealant was formulated to dry and form a monolithic seal that also acts as a barrier to airborne sound transmission. 3M Fire Barrier Sealant – CP 25WB+ – is a red, one-component, gun-grade, latex-based, intumescent firestop sealant. This fire barrier sealant helps control the spread of fire, smoke and noxious gases before, during and after exposure to a fire.
