Should you remove old insulation before adding new insulation?

• <div><p>You do not always need to remove old insulation before adding new.

You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.</p><p>However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam.

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: Is doubling up insulation a good idea?

• <div><p>Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.</p></div>

Q: Is installing crawl space insulation worth it?

• <div><p>Yes, <a href="https://www.angi.com/articles/why-should-i-insulate-my-crawl-space.htm">crawl space insulation is worth it</a> if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you&rsquo;ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.</p></div>

Q: How much difference does insulating a basement make?

• <div><p>Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors. While homes in mild climates won't gain as much benefit from having an insulated basement as those in cold climates, the effects are still noticeable on your energy bill.</p></div>
