Q: Do you need a vapor barrier when drywalling a garage?

• <div><p>If you plan on heating your garage, you must install a vapor barrier when drywalling the garage. A vapor barrier protects your garage from frost and mold that can occur through condensation. If your garage is unheated, you don't need to install a vapor barrier. The only exception is if you regularly crank the heat in your car before getting in it. In this case, you may still want to install a vapor barrier, as your car can heat your garage.</p></div>

Q: Does tin foil on windows help with heat?

• <div><p>Spreading tin foil over your windows works similarly to <a href="https://www.angi.com/articles/radiant-barrier-cost.htm">radiant barrier insulation</a>, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn&rsquo;t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.</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: Does wool insulation need a vapor barrier?

• <div><p>The primary reason that <a href="https://www.angi.com/articles/insulation-saves-you-money.htm">insulation saves you money</a> over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code. </p></div>

Q: What is the lifespan of crawl space insulation?

• <div><p>The lifespan of crawl space insulation depends on how well you maintain your insulation and the type of insulation. Fiberglass will need replacing every 15 to 20 years on average if you don't have a vapor barrier in place. If you do have vapor barriers in place, then your insulation could last much longer. Spray foam insulation can last anywhere from 80 to 100 years. </p></div>
