Spray foam insulation is a liquid polyurethane material that expands into a solid foam when applied. It seals gaps, cracks, and cavities, providing insulation and air sealing in one product.

Open-cell foam – Lighter, flexible, and more affordable; great for interior walls and sound reduction.

Closed-cell foam – Dense, rigid, higher R-value, and adds structural strength; ideal for basements, crawl spaces, and exterior walls.

Yes. Once properly installed and fully cured, spray foam insulation is inert and safe. During installation, occupants should leave the area for the recommended curing period (typically 24 hours).

Spray foam insulation can last 50 years or more when properly installed, often outlasting the structure itself.

Spray foam provides better air sealing and higher performance, but it costs more upfront. Fiberglass and cellulose are cheaper but do not seal air leaks as effectively.
