Hi! Insulating your garage can really help reduce heat. Start with the ceiling since hot air rises. Rigid foam boards or fiberglass batts are affordable and DIY-friendly. Next, focus on the garage door, which is a major heat source. Peel-and-stick insulation kits or reflective foil work well. To reduce garage heat with insulation, consider also adding insulation to the walls if your garage gets a lot of sun, though ceiling and door are usually more important. Also, add weatherstripping around doors and vents, and consider reflective window film or a vent fan. Even just ceiling and door insulation can noticeably keep your garage cooler.
I’m looking for advice on reducing the heat in my garage, especially during hot summer months. The garage gets extremely warm, making it uncomfortable and even affecting stored items. I’ve read that insulation can help, but I’m unsure which type is most effective for a garage. Should I insulate the walls, ceiling, doors, or all of them?
Also, are there any DIY-friendly materials or techniques that work best for keeping the garage cooler without breaking the bank? Any tips, personal experiences, or product recommendations would be greatly appreciated!
