Crawl Space Vapor Barriers For Encapsulation
So you’re deciding to encapsulate the crawl space, good for you. You have all the videos and guides to walk you through the process. It’s time to start buying your crawl space materials and you’re now looking at crawl space vapor barriers. Wow, with so many options, which one do you know is the right one? I spent a few weeks reviewing all the different vapor barriers I could find and documented that there’s only 2 with major status. They happen to be the top 2 highest reviewed barriers on the market today. One is a 12 mil, another is a 20 mil.
Crawl space encapsulation is a project and it’s one you want to make sure you get right on the first try. No added pressure, but we want to make sure you feel 100 percent confident in what you do. That’s why Crawl Space Encapsulation DIY is here, to walk you through the encapsulation process.
What Crawl Space Vapor Barriers Are Best For Encapsulation?
This is a common question we get. And rightfully so, because we’re an industry where quality matters. No two vapor barriers are the same and I’ll let you in on a secret, several companies sell their crawl space liners (vapor barrier) at less the size noted. What do I mean? Their 20 mil really isn’t a 20 mil, more like a 16 mil. Their 12 mil are closer to 10 mil. I don’t want you took advantage of and every homeowner deserves to know. It’s morally wrong and it’s business wrong. It’s false advertising and I could mention another dozen words but I won’t as you get the point.
How do we know which crawl space vapor barrier is the best? One word, reviews.
20 Mil SilverBack™ Crawl Space Vapor Barrier
The 20 mil SilverBack™ crawl space vapor barrier is top of the line quality with lower tier pricing, without a question one of the best and well priced liners on the market. This 20 mil vapor barrier has more reviews online than any other vapor barrier. In total, I found over 100+ reviews that hold the SilverBack™ as a high end product. On one of the main sites the SilverBack™ is sold, you can see above there’s 51 reviews with a 4.98 rating out of 5.0.
The great news, this quality liner comes in the 20 mil size and 12 mil size. Most of you will need a 12 mil or 20 mil vapor barrier to encapsulate your crawl space.
12 Mil GuardianLiner™ Crawl Space Vapor Barrier
The 12 mil GuardianLiner™ crawl space vapor barrier was the 2nd highest rated liner (overall) and the highest 12 mil vapor barrier I found online. This popular 12 mil crawl space liner came in just under 100 total online reviews, found the most on Crawl Space Repair.
Through the reviews, the GuardianLiner™ is very popular and one of the most sought after vapor barriers in the world. It was specifically designed to be used for crawl space encapsulation.
It has an antimicrobial layer to enhance its ability to resist mold and mildew, both are very common in the crawl space environment and very harmful.

It Should Be Noted
I wanted to note that both the SilverBack™ and GuardianLiner™ are accurate in their sizing. This means that the 12 mil and 20 mil sizes of the two vapor barriers are accurate. I bring this up because I know others that are not accurate, so please be careful buying other brands.
Reviews are an important role in my buying process, likely yours also. I always depend on reviews and I urge homeowners to do the same.
In this industry, you have to be careful what you buy. All crawl space products on the market are NOT the same.
