A High-Performance Intumescent Acrylic Sealant

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. It swells when heated, sealing a gap, protecting material underneath in the case of a fire.

  • Tested to treat the majority of the common applications found on a job site, including metal pipe, plastic pipe, insulated pipe, cables, ducts and multiple penetrations.
  • Advanced performance capabilities make TREMstop IA+ a best in class intumescent acrylic. This versatile firestopping product has exceptional sealant qualities, including superb unprimed adhesion.
  • Easy gunning.
  • Antifungal properties.
  • It can also be painted once fully cured.
  • Seals against airflow, which will help to reduce sound transmission for openings breached by penetration.
  • Smoke Stop for Partition Joints & Penetrations
