Q: Can you install a radiant barrier under insulation?

• <div><p>It&rsquo;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. </p></div>

Q: How much does a radiant barrier cost?

• <div><p>The <a href="https://www.angi.com/articles/radiant-barrier-cost.htm">cost to install a radiant barrier</a> ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot&mdash;which can add up quickly.</p></div>

Q: What types of insulation offer the best energy efficiency?

• <div><p>Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.</p></div>

Q: Is ceiling insulation worth it?

• <div><p>Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2. </p></div>
