Had lived in a house for 14 years, and the so called vapor barrier in the crawl space was relatively thin clear plastic which was torn up near the entrance to the crawl space due to HVAC and pest control people crawling over it over the years. We were putting our house on the market and wanted a durable vapor barrier that would look good and do the job for years. On a budget, we didn't want to pay the $3000 to $4000 for someone else to install, so looked for other options. We ordered the 12 Mil Crawl Space Vapor Barrier with GuardianLiner™ from CrawlSpaceRepair and have been very pleased. It arrived earlier than expected, and, with proper planning and cutting into the appropriate pieces, was easy to install. The tape worked well for connecting the recommended overlaps, and the finished product looks great. Since the house has been under contract, several people have been in the crawlspace (contractors, HVAC technicians, etc.) inspecting or making minor repairs, and all have praised the quality of the vapor barrier. It looks fresh and clean, and is clearly an improvement over the prior material. I highly recommend the product, and if you have any do it yourself skills, recommend you do the job instead of contracting it out. We did not encapsulate our crawl space, but this material would be great for encapsulation also.

Strong but easy to work with overall. Excellent vapor barrier. I know because I did test of the humidity in my crawl space before (usually around in high 60s%) and after (usually in the mid to high 50s%) It is a a huge difference and no more "crawl space" smell! Thanks!

We love the quality and durability of the Guardian 12 Mil reinforced vapor barrier for crawl space applications. It is easy to install and gives us the results we expect.

I highly recommend this product used in conjunction with the 3" waterproof tape.

 

Excellent vapor barrier material. I am so glad I ordered the SilverBack. One roll was enough to do my 42'x23' crawl space floor.

The 46" SilverBack vapor barrier was easy to work with and very tough. I found that with 24" walls, I had plenty for overlap with the floor pieces.
