8 MIL CRAWL SPACE VAPOR BARRIER

You don’t hear about 6 and 8 mil vapor barrier as much as you do the 12 and 20, but it doesn’t mean they’re less important. We commonly hear about the 12 mil vapor barrier and 20 mil vapor barrier when we’re discussing crawl space encapsulation. What you don’t hear about is the 6 mil liner and 8 mil liner. But why?

For one, most crawl spaces are large and require a thicker vapor barrier. For two, crawl space floors are often tough. Due to this, it’s recommended to at least use a 12 mil vapor barrier for your flooring. While that’s true, not all crawl spaces are created equal. You may very well have a small crawl space where a 8 mil crawl space vapor barrier is appropriate. If that’s the case, read on and learn which 8 mil vapor barrier we recommend.
