Vapor barrier tape is the perfect and quite affordable solution to protect moisture damage. If you’re looking to cover a relatively smaller area or only a portion of the floor, vapor barrier tape is the best alternative to large vapor barrier blocks. Vapor barrier tapes are made of prime polyethylene material to offer extreme sturdiness and longevity. Since vapor barrier tapes offer high adhere properties, they easily stick to any surface. It means that vapor barrier tape can be even installed all by yourself without any professional help.
