ToolGuy - Is that all the insulation that is needed (foam)? What about the plastic sheeting (visqueen)? Is that needed? I've heard/read differing ways of doing it, but was just wondering what is the most widely used and perhaps longer lasting. Please dont think of this as thread jacking, I was just trying to expand upon what had already been talked about.
