12 Mil Reinforced Vapor Barrier for Crawl Space Encapsulation
12 Mil Vapor Barrier 13'4"x50 

The 12 mil SilverBack™ crawl space vapor barrier is the best product to encapsulate a crawl space. Used by professionals to achieve results that back up their reputation.

This product is made in the USA and from premium grade ingredients. We do not cut corners on our products. The SilverBack™ crawl space vapor barrier naturally resists mold and mildew.

The Top-
The face is pure white with a slight glossy finish. You will notice the diamond pattern string reinforcement throughout the product. The pure white finish gives this crawl space vapor barrier a clean and finished look once installed.

The Middle-
In the center of the vapor barrier is a polyester cord that is secured into place with a molten layer of virgin polyethylene. This reinforcement will stop tears and contain any puncture damage to the area of initial damage. This reinforcement cord is very similar to the ones used in tires to keep the rubber from coming apart from the centrifugal force of rotation. The bond of the molten layer of polyethylene is superior to simply trying to remelt the front and back layers together. By introducing the molten layer it brings all the surfaces to the same temperature allowing a bond that is not just "remelted" but rather liquified together. This bond insures the SilverBack™ will never delaminate or allow air bubbles into the center.

The Back-
The back of this vapor barrier is silver in color and made from the same virgin polyethylene as the front layer. The color additives are for appearance only and do add a bit of cost to the product manufacturing. However, the color does not weaken the barrier in any way. 

The 12 Mil SilverBack™ is the best all around choice for most crawl spaces. It will handle light to medium storage requirements as well as traffic for regular home maintenance. If the SilverBack™ is going to be installed over sharp stone consider installing our Felt 550™ first to protect your SilverBack™ investment. This is the most popular SilverBack™ vapor barrier for crawl spaces due to its lower cost and high performance. 

Made 100% from premium grade virgin polyethylene resin. This Commercial Grade 12 Mil vapor barrier is true thickness, so our 12 Mil measures 12 Mil at the barrier not the string reinforcement. You get the absolute best quality and performance as well as the technical support you need to install our products and answer your questions. 

This 12 Mil SilverBack™ vapor barrier weighs 65 pounds (of plastic) per 1000 square feet. Compare that to the competitions 12 Mil @ 38 pounds per 1000 square foot. That is a 27 pound less per 1000 sq ft roll in material you are paying for. 

Due to the expanding and rising UPS handling and shipping fees we are forced to add $9.28 at checkout for each roll.

12 Mil = .012 inches

Rating Life Changing
I would like to thank CrawlSpace Repair again for all of their help. I don't think I would have attempted this without their good advice. This saved me at least a couple of thousand dollars, I'm sure. The bonus is that the finished basement area is now cool and dry so we can finally use it to store stuff. Life changing... I've already recommended CrawlSpace Repair to several friends.

It has been a year now since I installed your SilverBackâ„¢ liners and I'm still impressed with it. The basement is much dryer and a lot warmer, through last winter. This spring, which is when I used to have water laying on the dirt basement floor, there was no water. And no water showed up in any other part of the basement. 2 large thumbs up.

12 mil Vapor barrier is a quality product. Strong and easy to work with. If your planning to encapsulate your crawl space this is the right place to get all your materials. Excellent customer service and great installation advice. The humidity in my crawlspace is now between 40% and 50% even on the most hot and humid days. Smells coming from the dirt are also gone. Not sure why I waited so long to do this...oh yeah...working in a crawl space does kinda suck but once its done well worth it.

Rating Outstanding product.
I recently chose to encapsulate my crawl space myself after monitoring the humidity with a wireless hydrometer and discovering that the humidity can reach as high as 84% on certain days. I had several professional companies come out to quote the job...needless to say, way over priced. So, I did it myself using products from Crawlspace Repair. ALL of their products are super and make the job as easy as possible. Tough, durable and great instructions. Today, with benefit of dehumidifier, my crawl space is a constant maximum of 50% humidity and I am glad I did the project. Now, a number of my neighbors have expressed an interest in doing the same thing! It ain't rocket CAN DIY this project and save thousands. Just need patience (and a good back)!!

Rating Easy to work with
After receiving an expensive estimate for encapsulating my crawlspace, I decided to do it myself. This Silverback material was easy to work with in my opinion. I did most of the installation myself. I used a sharp pair of scissors to cut it. I used a drywall T and a sharpie to mark a straight line right on the back of the material.

Rating Crawlspace encapsulation
Despite being in a crawlspace, the experience was good! The materials were quality and the How To advice from the website was very helpful. I really appreciate crawlspacerepair's belief in the DIYer. I have an unfinished basement that I regularly use, but it was unfortunately open to the crawlspace... now it's encapsulated, the humidity is down, no more smell, and a much brighter, cleaner looking basement/crawlspace (also a solution to my high radon levels). One piece of advice that I heard somewhere but didn't take seriously- be smart about how you plan to unfold or unroll the barrier- I quickly found myself extremely stuck and frustrated in a ball of barrier. The first piece took me 30min to spread out in my 18inches of crawlspace. The second piece took me 5 minutes and a lot less sweat.

My project has been done for months now, but I wanted to wait to see the results. It is all you said it would be! As well as a clean crawl space, it has kept my floors much warmer in freezing temps, and odors are down from where they were. The house is warmer than it has been in the last 13 years!

I purchased the 12 Mil SilverBackâ„¢ to encapsulate the crawl space under our cabin. The products were all as described and of excellent quality. The space after installation looks great and there was immediate improvement by eliminating orders and moisture problems contributing to a musty smell.

So far I could not be more pleased with the white/silver liner I ordered to be installed in the crawl space of our home. I had obtained an estimate from a local company that specializes in crawl space solutions. The installed price was over $6,000. After some on line research I found your site and product information. The liner I purchased is very comparable with what the contractor uses. I could not afford a solution totally comparable to the contractor's solution which did have other components I chose to eliminate, but I believe this was a great compromise. Compromising saved me over $4,000!

What a quality product and what a difference it made putting this in the crawl space. The 12 mil. coupled with the anchors to hold the barrier to the stone was perfect. Before, I was smelling a fungus smell and I don't smell it anymore. Install was easy because I had my floor removed doing repairs. I'm not sure how it would be to install this in a tight crawl space, but it's worth it! Thanks Crawl Space Repair, I'll be referring my friends to buy this product.

Rating 18 Crawlspace
We had a wet, stinky crawlspace that is 18 high. The hardest part was cleaning out the wet insulation that had fallen down. Installation of the vapor barrier was actually the easy part. Don't hesitate to give the guys a call. The first space we did was 23'x7'. They suggested an approach for laying out the plastic that worked really well. Working with smaller pieces is easier than trying to do it with one big piece (unless you know how to hover with anti-gravity). We saved over $6,000 by doing this project ourselves. Well worth it. Don't forget your tyvek suit and respirator though. Insulation dust is very nasty.

Received this item quickly and it was heavier than I thought. I followed the directions from their web site and it all went as planned. After 38 years in my home with a damp and cold crawl space I now have a super clean and dry (No more mold) crawl space. I am looking forward to having warm floors this winter. I would recommend that you order extra white seam tape as you will probably use more than you think. Extremely glad to have done this project

Rating Best vapor barrier available
Went through 40 days of rain in this area last summer, leading to a musty smell in the house. I investigated the crawl and was shocked at how awful it was. I opened it up and put in industrial fans to ventilate and, yep, the problem got worse. First step was to fix the gutters and the grade against the foundation. Also discovered I needed a new roof and HVAC but I digress. Once the water entry sources were handled, I began the task of closing the crawl and replacing the existing 4 mil black plastic installed loosely over 10 years ago. I got some bids for this and was stunned. The crawl space is large - approx 3000 sf - but I figured I could take my time and do this myself and save at least 10K. This is not task to be taken lightly. The workspace is damp, dark, and cramped and nasty. Those who are afraid of rodents, snakes, spiders, etc should have someone else handle it. Found a way to wrap piers and walls from another vendor without drilling and anchoring and it is holding up very nicely. Actually got a sample of 12 mil from another vendor and it was vastly inferior to the 12 mil Silverback from Crawlspace repair. Ordered 12 mil for less used portions and 20 mil for the areas to and from the entry to HVAC. This product is thick, heavy and easy to work with. The laying of the vapor barrier was actually the easiest portion of this months long project. The product is virtually impossible to tear, but even the 20 mil can be punctured by sharp rocks underneath. As there is a gravelled french drain in my crawl, I also ordered some of the felt rolls to place beneath the vapor barrier. The tape I ordered was fairly easy to work with but does tend to split and get more difficult to use as you get deeper into the roll. The before/after photos are amazing, but the real difference is in the air quality in the house. Humidity levels in the crawl dropped from the 80s and 90s to less than 60 without dehumidification. Addition of dehumidifier has dropped that number to below 50 with a stable temp of 70. This produces a dewpoint in the crawl well below the temp of the coolest surfaces (HVAC ductwork) therefore condensation is gone. I will follow up on any additional findings. I did my research and the products on this site are outstanding and worth the extra cost. I don't plan on redoing this immense project anytime soon, so I wanted to do it right.

The service was phenomenal - especially as it had to cross from the US of A into Canada! We received the complete order, via UPS, in two working days. We were surprised and very happy - considering the day and time ordered! The quality of the SilverBack vapor barrier is perfect. It was easy to cut and install and the 4 Waterproof Seam Tape is powerful - once down, it is not going to come off without a fight! I was able to do the complete job on my own, just working at it a few hours a day, finishing within six days. This has been one of the very best buying and building experiences. The (telephone) service was friendly, knowledgeable - and instant! I would recommend CrawlSpace Repair as being first-rate, both company and product. Thank you for being there!

As an Architect practicing for over 30 years I took considerable time in researching and selecting this product for my personal house. A 1951 house with vented crawl space and no insulation.....the crawl space perimeter walls are now insulated, and the 12 Mil Silverback is in place and taped. I can already tell a difference....Now I am closing off the old exterior vents this weekend and have added HVAC duct air to temper the crawl space air. This product is very well constructed and is preforming. More later as the hot humid summer approaches...but I think this is going to be a good investment.

Rating Dry, Clean, All-White Encapsulation
I have been very pleased at the quality of the 12 Mil SilverBackâ„¢ vapor barrier and with the Waterproof Seam Tape. The 13'4 width has worked very well for sizing sheets to lay down between the concrete pillars, and even the manufactured seam at half this width has been a convenient guide for cutting smaller sizes to go up the end walls or on the pillars. I've never undertaken such a big task in such a big, dark, damp space. But I found that proper lighting and steady work in one area at a time led to success that grew until the whole project was done. I ended up with a dry, clean, all-white encapsulation and look forward to using my crawl space for storage now that a dehumidifier has been hooked up.
