Have you done the math to work out how quickly the insulation will pay for it's self with either of the heater options? By the sounds of it I'd be really shocked it it takes the entire heating season assuming you're using the shop daily.

Get the heater first so you can be relatively warm when you install the insulation.

Holding the garage 32F above ambient burns about $0.50/hr of fuel with R3, or $0.10/hr with R16. So the payback period is (very roughly) 500 hrs, or 20 continuous days of operation, or two tanks of propane instead of ten. I'm open to options other than propane, but bear in mind that this is very likely to be my last or second-last winter in this house. While I'm willing to do some work for the benefit of its future occupants, I think it's unlikely they'll appreciate a winterized garage. |
