If you’re in the market for a loose-fill insulation, cellulose is a great option. Made from recycled newspapers, this eco-friendly choice can be blown into ceiling and wall crevices with a special machine that can be rented at home improvement stores. This type of insulation is only good for insulating finished garages, as you can cut small holes in the walls and filling the cavities with cellulose, and patching the hole afterward.

Rigid Foam

Similar to fiberglass in that it comes in batts, rigid foam comes in 4 x 8-foot sections with thicknesses that range from one-half inch to four inches. This material is polystyrene and looks much like styrofoam. The R-value is one of the highest on the market and can be fashioned to fit most any space. If you’re looking to insulate your garage door, rigid foam is a great option. Because of its versatility, it can be easily placed under plywood in the sub-flooring to provide added insulation in a converted garage space. One safety consideration is to check the fire rating on the rigid foam insulation because not all are fire-resistant.

Garage Door Insulation

To make the most of your garage insulation, it’s important not to skip the garage door. Simply insulating the garage would be in vain because you’d leave a huge gap in your garage susceptible to unregulated temperatures. The garage door is often a weak link in thermal protection because it routinely opens and closes letting in outdoor air.

Garage door insulation can be difficult depending on the type of door you have because it’s not a solid piece and moves in up and down motions. Because of this variable, batt and spray foam insulations won’t work. Even products specifically designed for the garage door still have this issue because of the constant motion the garage door is in as it often flakes, peels, and pulls apart from the garage door. One of the wisest things you can do is to purchase a garage door that it already insulated, such as a fiberglass door with a foam core.

Garage insulation is imperative to an attached garage and there are many different types to choose from, depending on the needs of your home. It’s important to insulate the garage door for energy efficiency, but standard types of insulation makes this very difficult. Instead, invest in an insulated garage door.
