My fiancé and I just bought our house and of course the first project on my list is to complete my shop. I'll be converting our oversized 2-stall garage into the shop. The dimensions are 29'x23'. I've got a decent layout planned, although my fiancé's car will remain in the front of one stall...

So my first question for you all is what you suggest for insulation. The shop is standard 2x4 framed. Is the typical R13 going to cut it? I am in South Bend, IN. As far as the ceiling goes, I'm leaning toward simply closing off the small attic space and blowing in insulation up to about R39. Does this all sound sufficient?

As always, thank you for the advice! I'm really excited to get this started and move on to some true woodworking.

Thank you,
Matt
