Most Popular Thickness

12 Mil DrySpace™

The 12 Mil DrySpaceis by far our most popular crawl space vapor barrier due to the all around versatility for light storage and superior moisture protection. The SilverBack DrySpace™ vapor barrier is the only crawl space vapor barrier on the market that is actual thickness measured at the plastic and not at the thread.

   

 

   

Spray Foam Insulation

Where NOT to use it -

Closed cell spray foam is a great product for sealing out every little air leak. But, it will hinder your ability to inspect the structure if it is installed in the rim (band) joist area of the crawl space. This issue will come into play when selling a home or getting a termite inspection.
