Firestop

This category features commercial-grade firestop sealants, intumescent pillows, caulks, and specialized compounds engineered to prevent the spread of fire, smoke, and toxic fumes through structural penetrations. Vital for maintaining the integrity of fire-rated walls, floors, and ceilings, these products expand when exposed to high heat to tightly seal gaps around pipes, electrical conduits, and ductwork. Sourced from leading formulations tested to rigorous UL and ASTM standards, these solutions provide contractors, facility managers, and inspectors with code-compliant passive fire protection built to safeguard occupants and limit property damage.
