Tremco TREMstop® Fyre-Sil SL is a self-leveling, neutral-cure silicone firestop sealant designed for floor joint and through-penetration applications in fire-rated assemblies. Its self-leveling formula flows freely around multiple penetrations and into large or irregular joints, significantly reducing installation time in congested mechanical and electrical floors — no tooling required in most cases. With a Shore A hardness of just 15 and ±33% movement capability (UL 2079 Class I, II, III), it handles both static and dynamic joint conditions while maintaining a code-compliant firestop when installed per a tested system. Zero VOC, antifungal additive included, and rated for protection against washout conditions.
Ideal For: Floor penetration firestopping of metal and plastic pipes, cables and cable trays, ducts, and static and dynamic joints in concrete, wood, gypsum, and floor-ceiling assemblies — especially around multiple or congested penetrations where self-leveling saves time.
