True. I do have a related question for you if you'll permit a final digression while we're on this subject. What are your thoughts on vacuum insulation panels?

True. I do have a related question for you if you'll permit a final digression while we're on this subject. What are your thoughts on vacuum insulation panels? They have incredible R values, but leak over time. Do you see them being used in the housing of the future? I know somebody in Canada (the Leaf) is using them for a Tiny House project.
