Tremco Commercial Sealants & Waterproofing (CS&W) has introduced a new and improved formula for TREMstop®IA Intumescent Acrylic Firestop Sealant. TREMstop IA+ provides more coverage and requires less material for fire-rated applications. TREMstop IA+ is the only UL-classified intumescent acrylic firestop sealant on the market that can be installed around a four-inch plastic pipe without requiring a collar, sleeve or backer rod.
TREMstop IA+ is a high-performance, single-component, water-based firestop sealant that will expand to fill the voids left when combustible materials burn and deteriorate in a fire. This product has undergone third-party testing from Underwriters Laboratory Inc. and Intertek Group PLC to challenge its ability to perform under extreme conditions of water pressure and flames. TREMstop IA+ proved its effectiveness at treating 95% of the common applications found on a job site, including metal pipe, plastic pipe, insulated pipe, cables, ducts and multiple penetrations.
No priming is necessary for adhesion with TREMstop IA+. It is easy to gun and contains antifungal properties. In addition, it can be painted over once fully cured.
