This is probably two questions - 1. How do I insulate and 2. What should I insulate.
It's an old, single car garage attached to my home (built in 1942). It has no heat/cool source as of right now, and I'd probably just use a portable heat source in the winter. I live in MN and want to use this space as a workshop/tool shop/man-cave type space. The garage is bare studs, concrete floors and has a large, open, uninsulated attic above it. I'm probably looking at just fiberglass batts and then sheetrocking that - walls, ceiling and call it a day. Any help on choosing which R-value and tips on installing would be greatly appreciated. I'll probably also pick up a garage door insulation kit - just for good measure...
