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: What's the best R-value for installing insulation in a home?

• <div><p>The best R-value for home insulation depends on where you live and where you&rsquo;re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.</p></div>

Q: Do insulation companies need to be licensed?

• <div><p>In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi&rsquo;s <a href="https://www.angi.com/angi-license-check.htm">license lookup tool</a> to confirm whether or not an insulation contractor you&rsquo;re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.</p></div>

Q: Can I install insulation behind drywall myself?

• <div><p>Yes, you can <a href="https://www.angi.com/articles/how-to-install-insulation.htm">install insulation</a> behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you&rsquo;re looking to add insulation, it&rsquo;s better to hire a professional, as you&rsquo;ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.</p></div>

Q: Do you have to staple insulation?

• <div><p>You don&rsquo;t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it&rsquo;s an unnecessary step.</p><p>If you&rsquo;re adding a vapor barrier, you will need to staple that in place.</p></div>
