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>

Q: What happens if you don't install a vapor barrier?

• <div><p>While not every wall requires a vapor barrier, if you do need one and don&rsquo;t install it, moisture can get between the walls of your home. This can lead to water damage from mold growth or rot, and the excess moisture could also attract pests, including termites, cockroaches, or ants.</p></div>

Q: Do installations include soundproofing options?

• <div><p>Yes, professionals can add extra insulation or backing for enhanced sound control.</p></div>

Q: Should ductwork be wrapped in insulation?

• <div><p>Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated. </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>
