Spray Foam Insulation

Spray Foam Insulation

Spray foam is a complex material that is made from two liquid chemicals, typically isocyanate and polyol resins. Once sprayed, the foam rapidly expands on the surface. This mixture hardens to fill the gaps and cracks. When dried, the foam creates an effective air and vapor barrier, making it difficult for the heat energy and sound to pass through it.

Its applications include walls, attic surfaces and under floors. Spray foam insulation comes in two types, namely, closed cell and open cell. Closed cell has cells pressed together so no air or moisture gets in, making it a perfect choice for roofing, crawl spaces and basements. Open cell has cells left open for flexibility and softness. This is ideal for use in attics, walls and ceilings. However, it is breathable and can absorb moisture unless properly protected by vapor barriers.

Closed-Cell Foam

Higher R-value per inch, denser, water-resistant. We use closed-cell where moisture and structural rigidity matter most — basements, crawl spaces, metal roof decks, exterior continuous insulation.

Open-Cell Foam

Softer, more flexible, less dense, lower cost per square foot. We use open-cell for attics, interior walls, and ceilings where breathability is helpful and rigid moisture barriers aren't required.

Water Resistance

Spray foam water insulation can prevent water permeation. It creates a protective barrier which can remain water-resistant even during floods. Closed-cell specifically holds up against bulk water for extended periods — one of the reasons it's our pick for below-grade applications.

Energy Savings That Show Up on Your Bill

Homeowners switching from traditional batt insulation to properly installed spray foam routinely see 30–50% lower HVAC bills. The seal is so tight that we typically recommend a balanced ventilation system to maintain indoor air quality — which we'll spec into the quote.
