ceramic powder paint additive--really insulating?
Mentioned in Parade Mag today, in an article in reducing energy costs: adding a non-toxic ceramic powder to interior wall paint will insulate the room permanently.
Is this true? And if so, (how) does it change the look of the paint? Does it distribute evenly? When to put it in? What brand is the best/most accessible? Sounds like a wonderful upgrade, if it really is feasible.
