What are the four common types of insulation?

• <div><p>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.</p></div>

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’s <a href="https://www.angi.com/angi-license-check.htm">license lookup tool</a> to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.</p></div>

Can I install a radiant barrier myself?

• <div><p>It is possible to install a radiant barrier yourself. However, knowing <a href="https://www.angi.com/articles/how-install-radiant-barrier.htm">how to install a radiant barrier</a> and actually doing it are two totally different things. For example, it’s important that they be installed in a straight line but at an angle that creates a gap between the roof panels and the foil or spray. If this gap is too large or small, it won’t function as it should, and that may be hard to avoid if you’re only a novice. When in doubt, leave this job to a pro.</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.

Q: How long does fiberglass insulation last?

• <div><p>The <a href="https://www.angi.com/articles/when-should-i-replace-my-insulation.htm">life span of fiberglass insulation</a> can be as long as 80 to 100 years, but because of changing building codes, it&rsquo;s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames.
