Why Test?

Over the past 15 years there have been concerns about post encapsulation odors in crawl spaces being caused by the vapor barrier. There has been a lot of speculation about a possible connection between polyester string-reinforced vapor barrier and crawl space odors, off-gassing and volatile organic compounds. This speculation was created by suppliers who have been rejected by string reinforced vapor barrier manufactures. The suppliers use this false information as leverage, to disparage string reinforced vapor barrier and fill homeowners with a baseless fear of off-gassing, odors and VOC's. This has created a problem for crawl space professionals who offer polyester string-reinforced vapor barrier as an install option, but we are here to change that!
