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>

Q: How long does pipe insulation last?

• <div><p>Just <a href="https://www.angi.com/articles/when-should-i-replace-my-insulation.htm">how long insulation lasts</a> depends on the type of insulation you use. Fiberglass can last between 80 and 100 years, but it's important to start checking fiberglass insulation around the 15-year mark. Spray foam also has a long life span of up to 80 years, while mineral wool can last up to 100 years. Although eco-friendly, cellulose only has a lifespan of 20 to 30 years.</p></div>

Q: What type of window is best for insulation?

• <div><p>The most energy-efficient windows are double&mdash;or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn&rsquo;t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. </p></div>

Q: What insulation generally has the highest R-value?

• <div><p>Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they&rsquo;re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It&rsquo;s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.</p></div>

Q: Should I remove old cellulose insulation before installing new insulation?

• <div><p>Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there&rsquo;s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you&rsquo;re unsure how to assess the presence of mold or mildew, talk to a <a href="https://www.angi.com/companylist/mold-testing-and-remediation.htm">mold remediation specialist near you</a>.</p></div>
