A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.

If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.
