Insulation questions, answered by experts

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.
