Description

A one-part intumescent acrylic sealant that provides a firm, but flexible seal to joints in a variety of fire rated structures, as well as providing a good acoustic seal. It cures to form a tough tack free seal with excellent adhesion to a wide variety of building surfaces including plaster and wood. It is suitable for internal movement joints and perimeter pointing in acoustic partitions and structures, lap joints in fire rated cladding, sealing between fire doors and fire rated walls, sealing cable and pipe penetrations and for filling joints, voids and irregular holes in fire walls, partitions and other structures.

It has been specially formulated to give sound reduction properties when sealing and bonding plasterboard and other insulation boards. To seal potential air paths a continuous bead of the sealant should be applied to the perimeter of the partition and at all service penetrations.

The products have been tested to BS 476 Part 20 and BS EN ISO 140-3:1995.
