Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

The best paint for a garage door depends on the door's material, the desired finish, and durability requirements.

Paint Type

The type of paint you need often depends on the material of your garage door:

• Aluminum Doors: Typically require exterior acrylic paint.

• Vinyl and Wood Doors: Exterior latex paint is usually recommended.

• Steel Doors: Professionals often use latex or oil-based paint.

You can choose between acrylic, oil-based, and latex paints. Acrylic paint offers excellent UV and weather resistance and dries quickly, but may require multiple coats. Oil-based paints are very durable and may only need one coat, but they dry slowly and emit more VOCs. Latex paint is available in a wide range of colors and is forgiving to apply, but it can crack over time and may require a primer for even coverage. For an eco-friendly option, consider acrylic latex paint.

Paint Finish

You have a wide variety of finishes to choose from, including semi-gloss, gloss, satin, eggshell, and matte. The choice is largely based on personal preference, but many people opt for a semi-gloss or gloss finish. These finishes dry to a hard, durable surface that stands up well to humidity and regular wear and tear.

Regardless of the type or finish, it's crucial to use a quality exterior paint that can withstand the elements. Using a primer before painting will ensure better adhesion and a more even, long-lasting result.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

While you can technically use WD-40 to lube a garage door, it is not the best option since the oil it leaves behind can attract dirt. Instead, go to the hardware store and locate a lithium- or silicone- based garage grease. You can also search for garage door lubricant online; just make sure you get one that is made with lithium or silicone.
