How do I add insulation to existing walls?

• <div><p>If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install <a href="https://www.angi.com/articles/blown-in-insulation.htm">blown-in insulation</a>. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than <b>$100</b>. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.</p></div>

Q: What is the best insulation for crawl spaces?

• <div><p>Rigid foam insulation boards are one of the best insulation materials for crawl spaces. This material insulates the home well, resists water damage, and won't settle like fiberglass or cellulose. Closed-cell spray foam insulation is another effective insulation that both seals the air and provides excellent thermal protection for hard-to-reach spaces like crawl spaces.</p></div>

Q: How long does spray foam insulation last?

• <div><p>Spray foam insulation can last up to 80 to 100 years, making your investment worthwhile over the long run. Closed-cell spray foam tends to have the highest durability. Open-cell foam is subject to moisture, which can lead to deterioration. Remember that some spray foams will damage plastic piping, so consult a pro if you have PVC or CPVC pipes. </p></div>

Q: Can I use any type of insulation for my air ducts?

• <div><p>It's essential to use insulation materials specifically designed for air ducts. Common <a href="https://www.angi.com/articles/duct-insulation-types.htm">types of duct insulation</a> materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.</p></div>

Q: Will a dehumidifier stop condensation on ductwork?

• <div><p>A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won&rsquo;t solve the problem. </p></div>

Response following purchase was prompt but it took some time due to scheduling conflicts for initial visit. Electrical wiring work is being done on attic and insulation will be installed once that work is completed.
