<p>Rolls are not the size stated. They wouldn't send more to make up the difference. I had to buy a different product from another supplier to finish the job. Very unreliable company.

</p><p>Comment from CrawlSpaceRepair.com- Tim miscaluclated his vapor barrier needs and when he found out we do not sell partial rolls and we were not willing to open a new roll and cut him a 15' piece he posted this review. It is unfortunate that we could not meet his expectations. </p>

I was thinking about skipping these and securing the liner to the walls with a batten strip instead. I'm glad I bought them. They work great; you just need to drill a 1/4 hole and push them in.

Just wanted to share our first experience with your product. Since I'd never done this before, I really didn't know what to expect in terms of working with the product or time it would take to complete. On both scores, I would say we were pretty impressed. In this particular case, we had generally optimum conditions that will not always be present, but even so, 3 hours start to finish we had a very slick looking crawl space completed that the customer was very happy with. We look forward to working with you folks for a long time to come. Thank you again for all of your help in answering my questions to get us started.

I am encapsulating my own crawlspace. Used this 12 mil barrier throughout. It is highly puncture resistant and seems very durable.

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.
