40 Below is tested and approved for sealing the joints on Rigid barriers. Check for product compatibility with your Rigid Air Barrier supplier before installation.
Don’t apply any solvent based glues or adhesives/sealants to the tape as it may react with the adhesive. NOT suitable where screw sealability is required.
