How do you choose the right firestopping sealant? When the measuring stick is product performance, versatility, ease of application, and shear breadth of tested systems, STI SSS Firestop Sealant has been and remains the reigning champion of industrial-strength firestopping sealants!

Unmatched Performance: STI SSS Firestop Sealant reacts to heat using our patented and proprietary two-stage intumescent technology to expand rapidly to close off the path of smoke and hot gasses ahead of the advancing fire. Using active ingredients that are insoluble in water assures performance that is unaffected by humidity or moisture.

STI SSS Firestop Sealant adheres to all common construction surfaces and dries to form a tough yet flexible water-resistant seal that can be sanded and painted to match its surroundings if so desired. As little as 1/2″ is required to provide up to a 4 hour rating when tested to the rigorous requirements of UL 1479 (ASTM E 814).
