They work great, i wish they made some longer though so you can fit them through the foam insulation as well.

worked great!

Tape applied easily per easy instructions with immediate strong adherence. No separation of seams is apparent at close inspection several months later.

Perfect product for my crawlspace. I am 75 years old and installed it myself in one week-end. Received the order promptly in three days. Excellent service and good experience all around.

Great Tape. The last two years I tried to seal leaking joints in the crawl space using different tapes and methods with absolutely no success. This tape really works and does the job. It is worth the money you pay for it. The cleaner the surface the better it works, but even in lightly damp areas I had surprisingly good success.
