This tape is used to seal the seams of the crawl space vapor barrier. It comes in  4" x 187' rolls (compare to rolls at only 108') and is white to match all of the vapor barriers we offer. This product, when installed correctly, will give you a waterproof seal at the seams. In very wet conditions it is recommended to use the Foundation Seal Tape™ under the seam to give an extra layer of protection. This tape is the perfect thickness for this application allowing proper flexibility without sacrificing strength.  "Cheaper" tapes are known to release when they come in contact with moisture leaving your crawl space exposed. Just because other tapes are white does not make them the same. 

This product is Field Tested and the only tape we warranty on our installs.

The installers in my crawl space used a tape that is 2 3/4" wide. Given 2000 sq. ft. over time there were 3 areas that needed repair. The 4" tape is excellent for this task or even a new install. Tape is tight to pull (a good thing) an adheres very well. Overall a great value. Shipping costs are a bite but not a deal breaker. Like most products you get what you pay for! 5 Stars

Time will tell how well this tape holds. it sticks really well to the guardian liner and to the foam board that I used to insulate the walls. little bit hard to tape in the corners and around pier bases but overall seems to be high quality. Kind of expensive
