FAQs
What’s the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer and more flexible, ideal for interior applications with soundproofing benefits. Closed-cell foam is denser, more rigid, and provides a higher R-value for extreme insulation and moisture resistance.
What is spray foam insulation and how does it work?
Spray foam insulation is a high-performance material that expands on contact to seal gaps and create an airtight barrier. It helps regulate indoor temperature, reduce energy bills, and prevent moisture intrusion.
How much does spray foam insulation cost?
Costs vary based on the size of your space, insulation type, and project complexity. On average, spray foam insulation ranges from $1.50 to $3.50 per square foot. We offer free quotes to help you plan accurately.
Is spray foam insulation safe for my home or business?
Yes. Once cured, spray foam is non-toxic and safe for residential, commercial, and industrial use. We follow industry best practices to ensure safe installation and indoor air quality.
Can spray foam insulation help lower energy bills?
Absolutely. Spray foam reduces heat loss and air leakage, helping HVAC systems work more efficiently. Many homeowners see up to 30–50% savings on energy costs over time.
How long does spray foam insulation last?
Spray foam insulation can last over 20 years with no sagging or settling. It offers long-term protection without the need for replacement, unlike traditional fiberglass or cellulose.

Closed-cell spray foam is water-resistant and creates a moisture barrier that helps prevent mold, mildew, and rot in attics, crawlspaces, and basements.

Spray foam can be installed in walls, attics, crawl spaces, ceilings, basements, steel buildings, sheds, shipping containers, and more—perfect for both new builds and retrofits.
