The SpecSeal Series SIL Silicone Firestop Adhesive is a one-part, balanced silicone sealant that performs very well in projects requiring the sealing of gaps in walls and floors to restrict the spread of fire, smoke, poisonous gases, and water under fire conditions

The SpecSeal Series SIL Silicone Firestop Adhesive is intended for use in firestop systems to seal through penetrations and joints. This product shines in areas requiring increased water resistance.

SpecSeal Series SIL Silicone Firestop Sealer interacts with ambient moisture to generate a high-strength, long-lasting seal that adheres to most construction surfaces without the need for primers. Asbestos or PCBs are not included in SpecSeal products.
