Should you remove old insulation before adding new insulation?

• <div><p>You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. 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>

Q: What are the disadvantages of wool insulation?

• <div><p>Each of the three types of wool insulation has particular disadvantages. While their R-value is higher, they all cost more than fiberglass versions. Installing mineral wool and sheep wool requires protective gear. Because of its vulnerability to insects, chemicals are used in its production. Hemp wool is more costly to install than other types because additional tools and labor are involved. </p></div>

Q: How can you tell if ducts have enough insulation?

• <div><p>If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you&rsquo;re unsure, consider having your system&rsquo;s efficiency assessed by a local independent energy auditor.</p></div>

Q: Can I install insulation myself?

• <div><p>It is usually possible to <a href="https://www.angi.com/articles/6-things-know-installing-home-insulation.htm">install insulation</a> yourself, but it&rsquo;s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation&mdash;like blown-in and loose-fill insulation&mdash;demand a professional for proper functionality and safe installation.</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>
