FAQ

Answers To Common Questions

What insulation services does Nespor Contracting Inc. provide?
Nespor Contracting Inc. provides residential and commercial insulation services, including spray foam insulation, closed cell and open cell applications, attic insulation, basement insulation, and insulation for new construction and renovation projects.
What is spray foam insulation?
Spray foam insulation is an insulation material that expands after application to help seal gaps, cracks, and hard-to-reach areas. It can help improve energy efficiency and provide better air sealing.
What is the difference between closed cell and open cell spray foam?
Closed cell spray foam is denser and provides a strong moisture-resistant barrier, while open cell spray foam is lighter and expands more to fill larger spaces. The best option depends on the building, application area, and project goals.
Can you insulate attics and basements?
Yes. We provide insulation solutions for both attics and basements, helping address areas where heat loss, drafts, or moisture concerns may affect building performance.
