Can you post it a different way? I just sent an email to National Gypsum to see if I can buy the PCM drywall up here. I don't know if that is what you are referring to.

Sorry, I'll nut shell it.
PCM's or phase change materials are now being offered as a building material. Installed under the drywall they have a state change right around 70F to absorb or discharge heat. In a dwelling it would be useful to convert peak heating or cooling loads to off peak hours.

national said that they do not have anything on the market now even though they show up first with google
