Metacaulk® 1000 Intumescent Firestop Sealant 30oz Tube (Case of 12)

The Metacaulk 1000 Intumescent Firestop Sealant from RectorSeal is an exceptional solution for fireproofing and soundproofing various construction applications. This water-based, non-sag caulking sealant is designed for easy installation without the need for dilution or mixing, allowing you to use a standard caulking gun or even pump directly from the pail for larger jobs. Highly flexible and capable of withstanding vibration and movement, it forms a robust barrier in areas such as insulated pipes, wall construction joints, and between fire-rated gypsum wallboard partitions.
