crawl space

Posted by Todd on January 8th, 2001 08:54 AM

I previously asked about the heating of two rooms over a crawl space. One suggestion was to insulate with 2" blue board between the floor joists. I recently saw an ad for batt insulation made for underfloor insulation. It was advertised as great for crawl spaces and described it as having a reverse vapor barrier, with R-25. Manufactured by Johns-Manville? Any suggestions on this product and how to install it?
