Welcome to VaporBarrierPermeanceStudy.com

This website is dedicated to sharing the results of a blind vapor barrier permeance study conducted by Dr. Kay Cooksey, PhD at Clemson University. This study was anonymously organized/funded by Stego Industries to test the permeance of production (off-the-shelf) vapor barrier products.

The results of this study can be seen if you follow the links at the end of each page. This site was developed this way to encourage you to read each page carefully as the setup of this study is as important as the results themselves. It will only take a few minutes to get to the results. Remember, they will mean more if you understand the how and why before you see the what.
