Russ, i don't really know. Their website is rather vague. I assumed they used solid materials that were glued or wired in place, then coated with some kind of "glop" to smooth and tie everything together. But that is a complete assumption as I mention.
They also say they have insulating brick... and I assume this is for inside fireboxes and boilers and such. Sorry I don't have more info.
