Neoprene Rubber Sponge Stud & Joist Isolation Tape

Joist isolation tape is applied to the top surface of floor joists before installing subfloor panels to help reduce vibration and sound transfer between building components. The compressible foam layer creates a cushioning barrier between the joist and subfloor, which helps minimize squeaks, dampen impact noise, and improve overall acoustic performance in residential and commercial structures. It is commonly used in new construction, remodeling, and soundproofing projects where controlling structure-borne noise is important. The tape also helps create a more uniform surface for subfloor installation and can assist in sealing small gaps, contributing to a quieter and more stable flooring system.
