This tape worked well to seam the silverback 20 mil. Takes some practice to keep the tape straight and not stick it to itself working in a low crawl space. It does stick and seal well.

Used 10 mil plastic for barrier and tape held. Wasn’t quite as tight as I would have liked but still was great.

It's was a quick service & the product were what I expected, nice customer service. Thanks

It is a quality product. But I just installed it in my crawl, so have no idea on durability.

Quality tape that made seam sealing easy
