Professional Vapor Barrier Seam Tape & Butyl Tape
A matching long lasting tape used with WhiteCap Vapor barrier system.
Double sided butyl tape forms airtight seal between the liner and foundation wall.
I use the 20 mil vapor barrier from Nash on my crawl space projects. The product is heavy duty and the service from ordering through shipping is unbeatable!!!
I love using your crawl space vapor barriers! They're so easy to work with!
