The highest-performing insulation solution for residential and commercial buildings.
Spray polyurethane foam (SPF) is the gold standard in building insulation. Applied as a liquid that expands into a solid foam, it creates an airtight seal that dramatically reduces energy loss, blocks moisture infiltration, and strengthens structural integrity. ApexSeal NY installs both open-cell and closed-cell spray foam for new construction, retrofits, and commercial projects across NY, NJ, and CT.
Our crew inspects the space, identifies air leakage points, and prepares surfaces. We mask off areas to protect finishes and ensure proper adhesion.
We recommend open-cell foam for interior walls and sound dampening, or closed-cell for exterior applications, crawl spaces, and maximum R-value.
Two-component foam is mixed on-site and sprayed in controlled passes. The foam expands to fill every gap, crack, and cavity completely.
Foam cures within minutes. Excess material is trimmed flush, and the space is ventilated before re-occupancy per manufacturer guidelines.
We perform a final thermal scan and visual inspection to confirm complete coverage and no missed areas before signing off on the job.
You receive a full installation report including product data sheets, R-value certifications, and warranty documentation.
Closed-cell foam is denser, provides a higher R-value (R-6 to R-7 per inch), and acts as a vapor barrier. Open-cell foam is softer, less expensive, and excellent for sound dampening and interior applications where vapor permeability is acceptable.
Most residential projects are completed in one day. Larger commercial jobs may take 2–5 days depending on square footage and accessibility.
Yes. Once fully cured (typically 24 hours), spray foam is inert and safe. During application, occupants must vacate the space. We follow all EPA and manufacturer safety protocols.
Absolutely. We regularly retrofit spray foam into existing attics, crawl spaces, and rim joists without major disruption to your home.
Free estimates. Fast scheduling. No pressure.
