Q: What is the best insulation for air ducts in the crawl space?

• <div><p>Mineral wool wraps are the most affordable and effective insulation for crawl space ducts. They are easy to cut, last for a long time, and healthier for humans.

Q: How long does open-cell foam last?

• <div><p>Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for.

Closed-cell foam insulation has a longer life span of 30 to 50 years.</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.
