Sebastian, not sure if that question was directed at me. If so, I honestly have no idea. The reason I liked the room with the Stucco walls is that it ended up being the warmest room in the house during the winter. Our home was heated with portable kerosene heaters. Even properly vented, that was just a migraine waiting to happen. The warmth was a combination of things, not just the walls. You learn to economize space when 4 months out of the year your house is basically downsize to 1 room for a whole family. That downsizing let's you see how little you have to spend to enjoy the true things that make your space a home. Currently on my 30th move. I think I've taken downsizing to an extreme, this move my whole house was less than 2000 pounds move weight.
