Thanks for your thoughts on the idea. I was also consern'd about the lack of insulatino that steal would provide. A few factors actually work for me in this way. First, I have a finished basement with electric baseboard heating, so the temp won't be going to cold on the half that's finished. I was also thinking if I couldn't keep the ambient temp up high enough, tack glueing some styrofoam insulatino boards to the outside. Not pretty, but functional. So in these ways, I'm hoping to mitigate the poor insulation offer'd by steal. I'm trying to find any other issues I might come up with as well. Thanks much for your thoughts. If you have any other please do offer. I'm thinking as of now though, that I might give it a try.
