Firesound is formulated primarily to perform as a barrier to the incursion of fire through expansion joints and wall penetrations such as pipes or cables. Firesound is also an effective acoustic sealant.
It is ideal for sealing exterior and interior construction joints that
are subject to movement (up to +/-20%) in pre-cast concrete panels, block work and brickwork. Also suitable for filling gaps around cables, metal pipes, conduits, busways and ducts that penetrate walls, floors and ceilings. If joint movement is not required, Firesound can
be used as a putty for filling holes in fire rated substrates.
