Mastics & Foams

Stormflame Mastic, Fire Rated Sealants & Foam products

Intumescent Mastic, Fire Rated Foam & Sealants.

Standard construction foams and mastics provide little or no fire resistance. The range of products on this page can be 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 some of these products have good acoustic properties. For more information browse our range of sealing products.
