When I purchased my home here in The Villages five years ago, I replaced all windows with low-e Argon units, added radiant barrier in the attic as well as lanai and garage areas and also had the technician insulate my garage door. And yes, my house faces South. I can tell you that there was a dramatic difference when that garage door was insulated. In fact, I had considered having a new Clopay door with closed-cell insulation added to replace the original --- and only did not based on the technician's assurance that it would be overkill. He was right. Unlike you, I do not use my garage for any hobby work. And frankly, I made a commitment to myself that I would never put anything up in my attic -- and I haven't. I've heard too many stories about people here in TV who have been seriously injured hauling stuff up and down their attic stairs. So like the others, I vote that you do have your garage door insulated. It's a super cheap fix. And if it doesn't adequately cool your garage, you can always replace the door completely. That change 5 years ago would have cost me about $2,000. I can't imagine what the price would be today. Good luck and enjoy your space!
