SpecSeal SSS Firestop Sealant is a premium grade water-based Intumescent firestop sealant. SpecSeal SSS Sealant incorporates our proprietary two-stage intumescent technology making it the go to choice for any combustible or non-combustible penetrants. As little as a 1/2" applied depth of SSS Sealant is required to provide up to a 4 Hr Fire resistance rating when tested to ASTM E814/UL 1479.
SpecSeal LCI Firestop Sealant is a water-based intumescent sealant intended for a wide range of through-penetration and construction joint applications. SpecSeal LCI Sealant has excellent caulking properties making it easy to apply in vertical applications as well as overhead.
SpecSeal SIL300 Silicone Sealant is a high performance silicone firestop sealant tested to resist the passage of smoke, flame and water through construction joints and through-penetrations. SIL300 Sealant cures to form a flexible seal and carries a Class 1 W Rating for water resistance (Per ANSI/UL1479).
SpecSeal LC Endothermic Sealant is a latex-based gun grade firestop sealant for construction joints and non-combustible penetrations. After application, LC Sealant cures to form a flexible seal against the propagation of fire. Under fire exposure, LC absorbs heat and release water vapor resisting the progress of smoke and flame.

SpecSeal ES Sealant is a latex-based gun grade elastomeric firestop sealant designed for construction joint applications. Once cured, ES Sealant forms a flexible shield against the passage of fire and smoke. In dynamic joint conditions, ES Sealant is tested to accommodate up to 25% compression/extension of the installed joint width.

SpecSeal Smoke 'N' Sound Sealant is a high quality acrylic latex sealant designed for sealing through-penetrations (such as pipes, conduits, cabling, busways, openings), membrane penetrations (such as p-traps and outlet boxes) in smoke rated walls. SpecSeal Smoke 'N' Sound may also be used in linear applications such as wall-to-wall and head-of-wall joints where joints are designed to be either static or minimally dynamic. SpecSeal Smoke 'N' Sound Sealant is available in a single grade that has excellent caulking properties as well as high build properties on vertical or overhead surfaces. This single grade may be caulked (standard cartridge or bulk loaded), knifed or troweled. In addition, SpecSeal Smoke 'N' Sound contains no PCB's nor asbestos.
STI leads the industry in developing innovative fire protection systems that help stop the spread of fire, smoke and hot gases. For over 30 years, our team has worked hand in hand with the construction industry to create simple solutions to complex firestopping problems. Our SpecSeal® and EZ Path® product lines are engineered to deliver powerful performance. Because our system designs are user-driven, they are easier to apply. The result is simply designed, outstanding fire protection systems which often result in lower installed costs. STI products and systems offer innovative firestop solutions for all types of new construction and retrofit applications. Since firestopping is our only business, we concentrate all our resources on providing the highest quality, fully tested, innovative firestopping solutions.
