Q: What is the best type of insulation for crawl spaces?

• <div><p>Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.</p></div>

Q: How much difference does a radiant barrier make?

• <div><p>According to a report from <a href="https://www.energy.gov/energysaver/radiant-barriers#:~:text=Some%20studies%20show%20that%20radiant,to%20add%20a%20radiant%20barrier.">Energy.gov</a>, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. </p></div>

Q: How can you tell if ducts have enough insulation?

• <div><p>If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you&rsquo;re unsure, consider having your system&rsquo;s efficiency assessed by a local independent energy auditor.</p></div>

Q: What do you put behind board and batten siding?

• <div><p>When installing board and batten siding, make sure there is wall sheathing <i>and</i> a moisture-resistant barrier installed. Behind that sheathing should be plywood or OSB for you to nail the boards and battens into. If there isn&rsquo;t plywood or OSB, you can install vertical furring strips at 1&frac12;- to 2-foot intervals to nail the boards and battens to.</p></div>
