Q: Is it worth insulating ductwork in a crawl space?

• <div><p>Yes, insulating ductwork in a crawl space is a worthwhile investment, especially if you live in a colder climate or run your air conditioning for most of the year. Uninsulated ducts can lose up to 30% of their heating and cooling efficiency, which can significantly impact your electricity bill. The project is a relatively small investment and typically only takes a few hours. It's a particularly simple add-on if you are already hiring someone to insulate the entire crawl space. An added benefit is that insulated ducts put off less hot or cold air, making them less attractive to pests.</p></div>

Q: Do installations include soundproofing options?

• <div><p>Yes, professionals can add extra insulation or backing for enhanced sound control.</p></div>

Q: What types of insulation offer the best energy efficiency?

• <div><p>Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.</p></div>

Q: Should you put plastic over insulation in basement walls?

• <div><p>A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.</p></div>
