Keep my garage moisture free

Ok guys, after some additional research I think I have a plan for what I am going to do. I think I am going to use 1 inch polyiso foam boards (foil on both sides). And place them between the beams, while foil taping the exposed metal on the beams to prevent condensation (does that sound right?).

Once the foam boards are up, I plan on using a thick plastic vapor barrier to cover the foam board insulation. I’ll be insulating the walls first, and then the roof. Once the building is fully insulated, I plan on installing a wood burning heater along the back wall (the wall across from the large doors) towards the center of the wall so it can heat the shop evenly.

IMO this should be a relatively simple, cost effective way of insulating my shop.

what do you guys think?
