  A: I have experience working with fiberglass, foam, cellulose, mineral wool, and spray insulation.
• 7. Can you explain the difference between closed-cell and open-cell spray foam insulation?
  A: Closed-cell foam is denser, has a higher R-value (thermal resistance), and is moisture-resistant, making it suitable for both interior and exterior applications. Open-cell foam is less dense, has a lower R-value, and is generally used for interior insulation.
• 8. How do you determine the appropriate R-value for a specific project?
  A: I consider factors such as local climate, building type, and building codes to determine the recommended R-value for a project. I also consult resources such as the U.S. Department of Energy's insulation guide.
• 9. Can you walk us through the installation process for fiberglass batt insulation?
  A: First, I measure the area to determine the amount of insulation needed. Then, I cut the batts to fit the spaces and staple them to the studs or joists. Lastly, I ensure all gaps and seams are sealed for maximum efficiency.
• 10. Have you worked with any insulation software or tools? If so, which ones?
  A: Yes, I have experience with insulation calculation tools such as the Owens Corning Insulation Solutions Calculators and Top Savr, an energy savings calculator.
