Blue Summit Supplies Vapor Barrier Tape is a 60-yard roll of 9 mil waterproof poly film with a synthetic rubber adhesive, 3.78 inches wide, meant for sealing crawl space and basement vapor barriers, PE plastic liners and insulation seams. The thick film and permanent rubber adhesive are built for a lasting seal on polyethylene sheeting, and the same roll is pitched for marine, stucco and underlayment jobs. It suits homeowners and contractors sealing a crawl space liner or patching a torn barrier. Against thinner general-purpose sheathing tapes, the 9 mil film resists tears and punctures better, but it is heavier and less flexible around tight corners.
