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 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).
WF300 Intumescent Firestop Caulk is a latex-based firestop caulk designed for residential wood frame construction. WF300 Caulk is tested for addressing penetrations through wood/frame construction such as wood stud walls and floor/ceiling assemblies. Under fire exposure, WF300 expands to up to four times its original volume.
Designed for easy installation in non-rated floor, ceilings, and walls, EZ Path Series 33NEZ Smoke & Acoustical Pathway provides exceptional cable capacity with tested and approved cable capacities ranging from 0 up to 100% visual fill. A single unit installed in a wall exceeds the cable carrying capacity of a 4" (102 mm) sleeve utilizing typical putty firestop systems (35% cable loading).
Designed for easy installation in non-rated floors and walls, EZ Path Series 44NEZ Smoke & Acoustical Pathway provides exceptional leakage and acoustical performance with tested and approved cable capacities ranging from 0 up to 100% visual fill. A single unit has equivalent cable capacity to the Series 44+ Fire-Rated Pathway providing consistency of performance across the low-voltage pathway regardless of barrier type.
