My question is regarding insulation and wall covering. I have not insulated yet (1 bill at a time!) and was thinking about doing R19 in between the joists and R11 in the walls. (I'm in the mid-south - think Memphis). I feel like this would be adequate in the winter months, but will it do anything for me in the hot, humid summers (I'll buy a window A/C next year.) Should I have anything directly under the roof decking & rafters?
Also, are the any options to drywall for a ceiling and walls? I loved Matthew Teagues idea of using the T-111 on the _in_side for a wall covering, namely it's strength, and I really hate sheetrock, but the T-111 would be expensive. Ideas?
Finally, would it make much difference to just lay drywall on top of the joists and then the insulation on top of that? (I'm thinking I'd like to use the joists for hanging things, and gain that extra 5.5" of space.
Thanks for any ideas! Duke
