Kamco’s Fire Stopping, Sealants & Caulking category provides contractors with code-compliant solutions for maintaining fire-rated assemblies while sealing joints, penetrations, and gaps. At Kamco Supply Corp of Boston, we stock professional-grade firestopping and sealant products trusted on commercial, multifamily, and institutional projects throughout New England.
This category includes fire-rated sealants, intumescent caulks, and firestop materials designed to restore the integrity of fire-resistance–rated walls and floors where pipes, conduit, cables, and ducts pass through. Proper fire stopping is critical for slowing the spread of fire and smoke, meeting life-safety codes, and passing inspections. Contractors rely on products that are easy to apply, adhere to multiple substrates, and meet UL and ASTM testing requirements.
In addition to fire-rated applications, this category supports general sealing needs where durability, flexibility, and long-term performance are required. Whether you’re working on new construction, tenant fit-outs, or retrofit projects, Kamco offers jobsite-ready quantities that help crews work efficiently and stay compliant.
