this article contains wrong information
This is incorrect. Vapor barrier and vapor retarder are NOT the same. I tried to edit the article, but for no reason it was reverted by automated BOT. I have searched everywhere for help, but the help section on wikipedia is very difficult to use... I have spent 30 minutes, and still cannot find a way to resolve it. I'm giving up but I would like to post the following information here just for anyone who's looking at this article so they know that it is incorrect.

A vapor barrier is not the same as a vapor retarder. According to AMERICAN CONCRETE INSTITUTE (ACI 302.1R-96), a vapor retarder is a material with a perm rating less than .3 perms, where as a vapor barrier is a material with a perm rating of .3 perms or greater. However, according to AMERICAN SOCIETY FOR TESTING MATERIALS (ASTM), the terms vapor retarder and vapor barrier are interchangeable. In general practice, vapor barrier refers to a barrier that has a higher performance than a vapor retarder.
