Butyl Tape - Permanent Reinforced D/C Black BTR-40 4INx36YD 40MIL 3/CS 144/SKID

Polyken BTR-40 Double-Coated Reinforced Butyl Tape is designed for the installation of crawl space vapour barriers and effectively laminates and bonds various substrates while preventing air penetration. It offers noise and vibration damping, along with waterproofing and weatherproofing capabilities, thanks to its aggressive butyl mastic adhesive that adheres to both smooth and textured surfaces. This tape creates a permanent air and water-tight bond and is compatible with most sealants, maintaining flexibility in cold conditions and structural integrity in high temperatures. The cloth reinforcement enhances strength and dimensional stability, and the tape is hand tearable, featuring a PET film liner for easy peeling and application.
