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. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.</p></div>

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.

Q: Is it worth it to remove old attic insulation?

• <div><p>The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.</p></div>

Q: What maintenance is needed after installing insulation?

• <div><p>Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.</p></div>

Q: How do I know if my insulation needs replacing?

• <div><p>One of the clearest signs that your insulation isn&rsquo;t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona&mdash;this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.</p></div>
