Looking to improve your garage’s comfort and energy efficiency? Insulating your garage can reduce heat loss, lower utility bills, and make it more usable year-round. Popular solutions include fiberglass batts, ideal for walls and ceilings; spray foam, which provides excellent air sealing; and rigid foam panels, perfect for a DIY-friendly approach. Don’t forget garage doors—adding insulation or upgrading to insulated doors can make a big difference. Proper vapor barriers and air sealing help prevent moisture issues. Choosing the right insulation depends on your climate, budget, and whether you plan to convert the garage into a functional living space.
