It’s about super therm and that all out attack that the blog went on. I don’t think I’ve ever heard anything about them using that to insulate the inside of a house. Everything they say is to put on the outside to block the sun. Attacking it saying its a bad product is wrong and ignorant. The man that decided to do the inside and outside of his house is a fool. It is only to be applied to the outside wall and roof of your home that’s it. Common sense should dictate that ceramics in anything are not designed to hold heat but to make a barrier. You coat the outside and insulate the inside so your insulation traps and holds the heat needed and the outside blocks everything that’s unwanted. Every video I’ve found of licensed installers only apply it to the outside and even their own statements are to apply to the outside. So attacking it as being bad is becoming of this site.
