The high-performance, single-component, water-based, firestop sealant TREMstop IA+ will expand to fill voids left when combustible materials burn and deteriorate in a fire. The improved formula for TREMstop IA provides more coverage and requires less material for fire-rated applications. It can be installed around a 4-inch plastic pipe without requiring a collar, sleeve, or backer rod. According to the manufacturer, the sealant proved its effectiveness for treating 95 percent of the common applications found on a jobsite, including metal pipe, plastic pipe, insulated pipe, cables, ducts, and multiple penetrations. The sealant has antifungal properties, can be applied with conventional caulking equipment, and can be painted over once it is cured. No priming is necessary for adhesion.
