6 MIL CRAWL SPACE VAPOR BARRIER
While 6 mil vapor barriers are not as commonly used as the 12 mil vapor barrier and 20 mil vapor barrier, they still can be used in the crawl space. While we don’t personally recommend the 6 mil liner for crawl space floors, there’s no reason why 6 mil vapor barriers can’t be used on foundation walls.
Using 6 Mil Vapor Barriers
With a smaller crawl space vapor barrier, it’s very important to note that it’s extremely important to have a quality 6 mil liner and not a cheap wanna-be version that can leave you with more harm than good. There’s not much difference between 6 mil liners and 8 mil liners, two of the smaller crawl space vapor barrier sizes.
6 mil crawl space vapor barriers are mainly used for lining the walls and piers of your crawl space. While most people use 12 mil and 20 mil vapor barriers, if you have a small crawl space or small height in the crawl space, a 12 mil vapor barrier may be too big for you to use. If this is your scenario, the 6 mil liner may be the route to go. It’s not uncommon to see walls and piers with 6 mil, there’s
nothing wrong with that. It all depends on your crawl space and exactly what’s going on.
There’s a fair share of 6 mil crawl space vapor barriers on the market. If you’re new to the site, we’ve been encapsulating crawl spaces for decades. So over this time, we have dealt with many 6 mil liners over the years. One of the highest recommended 6 mil vapor barriers is the 6 mil DiamondBack vapor barrier offered by CrawlSpaceVaporBarrier.net.

We’ve learned that the 6 mil liner is great for encapsulating walls and piers. Again, rarely do we use 6 mil liners on the floor. Even with no storage on the vapor barrier, it would be best to use a 12 mil vapor barrier at the least.
