I was unable to search the forum. I keep getting an error and I wanted to see if there was any more info on Thermal Core phase-changing drywall. I cant seem to find any more info or news about it. Seems like there was a lot of chatter about it around 2009 but then nothing more. No info that I can find on National Gypsum's website either. Thanks.

I found the same problem, I believe the two companies dropped the product line by 2012, even though it is available in Europe off the shelf. I am building an off rid modern house and seeking PCM, let me know what you find, I will do likewise. I will send you a PM Nick from Utah

PC drywall has been talked about for at least ten years. US National Gypsum makes it and it was being tested in CA. I suspect it has some issues that need to get sorted out before and if it will ever become mainstream. We discussed it on the Build it Solar forum several years ago:

Thanks for the info. I wish that there was some official follow up to indicate if it is being dropped or still progressing to market.
