The Roxul Comfortboard has been gaining steam and reputation as a replacement for the plastechhh foam boards. Much lower GHG potential and toxicity, doesn’t burn (made of recycled steel and volcanic rock), deals with vapor and water nicely, tight, quiet, and Roxul is picking up documentation on hanging it. Only downside is availability in your area may still be dicey. <BR>
