Insulation questions, answered by experts

Garage doors that are not insulated can be a major source of heat loss. That’s why it’s essential to winterize your garage door with insulation and weather stripping to prevent heat loss and keep it warm more easily. Consult a local garage door installer if you need help determining the cause of your garage losing heat.

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

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.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.
