The GuardianLiner™ brand can be found at CrawlSpaceRepair.com. In the crawl space industry, it’s no secret that Crawl Space Repair is well known for its high quality products and this 12 mil crawl space liner is no different. While vapor barriers can be found in 6 mil, 8 mil and 20 mil, the 12 mil is one of the most widely used sizes in the crawl space. 12 mil liners are used for both foundation walls and crawl space floors.

We usually recommend the 12 mil crawl space vapor barrier for crawl spaces that have medium volume traffic and storage in the crawl space. You don’t want to skip out on quality and go cheap though, it can end up costing more in the long term. Out of all the 12 mil barriers on the market, the 12 mil GuardianLiner™ is among the highest reviewed and widely used.

This crawl space liner is made in America and manufactured by CrawlSpace Concepts.  This 12 mil has a basic string reinforced vapor barrier that is commonly compared to most other brands on the open market for the same pronounced thickness, 12 Mil. Actual 12 mil is equal to .012″, not 12mm. 

The GuardianLiner™ 12 mil crawl space vapor barrier does not contain additives and is reinforced with a 1000 denier polyester cord to stabilize the layers and prevent the vapor barrier from ripping.

One way of distinguishing vapor barriers is by looking at the actual appearance of the crawl space liner. In this case, the GuardianLiner™ is bright white on the face and black on the back. This is a common color scheme you see in crawl space vapor barriers, but make no mistake, other vapor barriers don’t compare.

If you review the GuardianLiner™ 12 mil crawl space vapor barrier with other liners, you’ll find that the GuardianLiner™ is higher quality and thicker. This is not to knock other brands, but rather just a fact. So take a note, if you see a vapor barrier with the same black and white color scheme, it does not represent that you’re getting the same quality in your product.

You will find this, like all of our crawl space liners, are made in the USA. This product is available in the roll size of 13’4″ x 75′.

However, prior to shipping we fold the vapor barrier in half and roll it on an 82″ core.
