Intumescent & Acoustic Sealant

Intumescent and acoustic sealant is designed not to support combustion and when subjected to heat, chars and intumesces preventing the spread of smoke and fire through joints.

Designed for sealing joints, voids, and irregular holes in fire walls, floors, partitions and other structures and for maintaining their inegrity when sealing around pipes and cables that penetrate them. Also ideally suited for perimeter pointing of fire rated door and window frames.

Formulated to work in joints up to 25mm wide with no slump and having excellent application and tooling properties. Available in white and grey as standard colours. Other colours can be supplied upon request. The sealant has Certifire certification with a wide field of application which can be included as part of the product features of your brand. Tested to BS 476: Part 20:1987 and EN 1366-3 for fire protection joints and in accordance with BS EN ISO 140-3:1995 for acoustic performance.

Customers who conduct their own tests can be reassured that the sealant will perform both acoustically and in a fire.
