Great tape works perfect and does the job needed to do. Plenty of tape in each roll highly recommended

This tape does a pretty good job of sealing the walls of your crawlspace. You really need the pins to ensure long life for the encapsulation to stay in place. I did my best to dust the walls but still had some areas where it didn't stick the greatest. Overall it does a good job when paired with the pins.

I used the tape to join vapor barrier on the ground in my crawl space. It did everything it said it would. I liked the wide width, it sticks very well to the plastic and I would up over-taping the seams on the plastic draping my foundation walls because it was much superior to what I had originally used

The first time you remodel and have troops of trades people crawling around on your vapor barrier you'll be glad for the extra mils. I was completely comfortable moving my furnace and water heater into the crawl space to free up living space because the 20 mils will stand up to installation and maintenance traffic.

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
