Description
This tape is used to seal the seams of the SilverBack™ vapor barrier. It comes in rolls 4" x 187' (compare to rolls at only 108') and is white to match the SilverBack™ barrier. This product, when installed correctly, will give you a waterproof seal at the seams. In very wet conditions it is recommended to use the Foundation Seal Tape under the seam to give an extra layer of protection. This tape is the perfect thickness for this application allowing proper flexibility without sacrificing strength. This product uses a pressure sensitive adhesive that achieves 100% strength in 15 minutes at 70 degrees F. "Cheaper" tapes are known to release when they come in contact with moisture leaving your crawl space exposed. Because other tapes are white does not make them the same.
*This product is Field Tested and the only tape we warranty on our installs. 

If you save $5 on a roll of tape and it fails, did you save $5?

How much do you need?
**Here is the guide we go by- 1 roll of WST for every 500 Sq Ft of floor space rounded up. For example; 400 Sq Ft you need 1 roll, 700 Sq Ft you will need 2 rolls, 1600 Sq Ft you will need 4 rolls etc. In addition you will need one roll for every 6- 8x8 or 8x16 support. 

Case includes 12 rolls- Save 15% on orders of 12 or more rolls.

Features:

Pressure sensitive adhesive
Water/Moisture will not dissolve the adhesive like other tapes
Bright white, matches the SilverBack™ perfectly
4" x 187'
Will not turn pink
Adhesive does not off gas (give off chemical smell)
Customer Reviews
Rating Excellent products!
 
I am very happy with the result since we converted a vented space that was a nightmare into one that was actually pleasant to be in. It should pay in utility bill dividends over the next few years.

Thanks for the follow up. Your products were more than what I expected, but I can't say enough about the excellent support I received from your staff. I'm hoping to use your products on another project I may have coming up soon.

Used the crawlspacevaporbarrier.com system with 12 mil walls and 20 mil floor. All products very high quality. Seam tape works as advertised and I wouldn't substitute a lesser product. Buy plenty- maybe 3 times more than you think you will need. Keep you tools sharp and clean from adhesive to avoid frustration.

This tape is excellent at sealing the vapor barrier seams together. It is very sticky and strong. Once its on the vapor barrier, its almost like it becomes part of the barrier.

I found this tape very easy to work with and it seals very well. Ideally its a two person job, but I did most of the taping by myself.

I have recently purchase a 12 mil crawlspace membrane, the foundation tape, the waterproof seam tape and the pins. I was very impress with the quality of the products, the crawlspace of my chalet is now clean and no more smelling or humidity. As an general contractor this is the kind of product we are looking for, I have decided to offer the product to my own customer, this is definitely way much better that the 6 mil polyethylene that the CNB suggest we install in crawlspace. The membrane is very resistant and will last for years to come. Thanks for an awesome price. André Allaire General Contractor Vita Project inc.

Well, this is just an outstanding product. I love the way it drapes over concrete footings, the material just seems to naturally hug 90 degree transitions, far better than you would imagine.

. All materials and supplies were as advertised. The foundation tape, the water proof seam tape, and the vapor barrier fasteners worked exactly as advertised. I could not have been more pleased with the products.

This vapor barrier tape was great. I was most impressed with its thickness and ease of workability. Once I got the hang of tearing it, folding, tucking and taping the vapor barrier my project went fairly smoothly. This product along with the outstanding support and recommendations by the staff helped make my project a success.

This tape works great but I ran short twice. It is expensive and you will use more than you think specially around corners. I looked at using white duck tape at lowes for 7bucks.
