Hey, I'm gearing up to give this a try. Thanks for the awesome info and pics. I have a question about the foam insulation sheets. I'm not exactly sure what you're talking about. Is this the stuff:

SUPER TUFF-R 1-3/8 In. 4 x 8 Polyisocyanurate Rigid Foam Insulation - 1347 at The Home Depot

Thanks again.
