What Spray Foam Insulation Does

Spray foam insulation expands on contact to fill gaps, cracks, and irregular cavities that batts and blown-in material can't fully address. The result is both insulation and an air seal in a single application — reducing heat transfer and stopping air infiltration at the same time.

For Gloucester County homeowners, that combination matters year-round. Cold winters drive up heating costs when warm air escapes through poorly sealed attic hatches, rim joists, and wall cavities. Hot, humid South Jersey summers push those same costs in the opposite direction. Spray foam addresses both by treating air leakage, not just conductive heat loss.

We install spray foam in attics, crawl spaces, rim joists, exterior walls, and in new construction and renovation applications throughout Gloucester County and surrounding communities.

Closed-Cell vs. Open-Cell Spray Foam

Higher R-Value · Vapor Barrier

Closed-Cell Spray Foam

Dense, rigid foam with a high R-value per inch. Resists moisture and acts as a vapor retarder, making it the preferred choice for crawl spaces, basement rim joists, exterior walls, and anywhere moisture is a concern. Also adds structural rigidity to the surfaces it bonds to.

Cost-Effective · Interior Applications

Open-Cell Spray Foam

Lighter, softer foam that expands significantly on application. Effective for attic rooflines, interior wall cavities, and areas where moisture control is less critical. Provides excellent sound dampening as a secondary benefit. Typically lower cost per square foot than closed-cell.

Spray Foam FAQs

What's the difference between closed-cell and open-cell spray foam?
Closed-cell is denser with a higher R-value per inch and acts as a vapor barrier — ideal for crawl spaces, rim joists, and exterior walls. Open-cell is lighter and more cost-effective, suited for attic rooflines and interior walls where moisture is less of a concern.
Can spray foam be installed over existing insulation?
In some cases, yes — but it depends on where the existing insulation is and its current condition. We assess the situation during your free estimate and tell you exactly what makes sense.
How long does spray foam last?
When properly installed, spray foam is highly durable and typically lasts the life of the home. It doesn't sag, compress, or settle the way fiberglass batt insulation can over time.
