Intumescent Mastic : Fire Rated Sealants & Foam

Standard construction foams and mastics provide little or no fire resistance. These products are used where fire stopping properties are required, for example, mastic sealing around other fire rated products and foam for gap filling.

Where reduced noise transmission is required these products have good acoustic properties.

The Low Smoke & Toxicity Sealant is specially formulated for use in passenger tunnels and similar situations where the fire stopping intumescent should not create additional smoke or toxicity hazards for evacuees or emergency services.
