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. Meanwhile, fiberglass wraps are cheaper but more hazardous and difficult to handle. If you do choose to use a fiberglass wrap, make sure you are wearing long sleeves and wear proper protective gear.</p></div>

Q: How much difference does insulating a basement make?

• <div><p>Heat lost through uninsulated basement walls can account for up to 30% of the total energy lost through heat transfer to the outdoors.
