Insulation questions, answered by experts

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

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.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.
