Really? I'd be interested to know what the current state of the art for "done right" is in this area. I saw such a room constructed once, about 10-15 years ago: it had "wallpaper" with a conductive grid printed on the back, and long strips of copper tape running up each corner of the room to ensure that all the sides were shorted together. There was chicken-wire-like mesh in the ceiling (this made running cables a real pain!) and I'm not sure what was in the floor. But I wouldn't call anything I saw there particularly good thermal insulation.
I've always figured this must just be how it's done. Is there some other method?
