Attic
Attic insulation limits heat transfer at the top of the home. Air sealing at the ceiling plane helps address drafts and upstairs temperature differences.

Open-cell vs. closed-cell.
Two spray foams, very different behavior. Here's how they compare — and why only one makes sense in our climate.
Open-cell spray foam
Not recommended hereOpen-cell spray polyurethane foam is a soft, flexible, lower-density insulation whose cells are mostly open. It expands greatly on application, filling cavities and sealing air leaks, but it is vapor-permeable and can absorb water.
- Appearance
- Cells are open and interconnected; cured foam is soft and spongy
- Density
- Typically about 0.5 lb/ft³; density varies by product
- Typical R-value
- Typically R-3.5 to R-3.8 per inch; use the specific product's published R-value
- Air sealing
- Acts as an air barrier at sufficient thickness (often around 3+ inches) with continuous coverage
- Vapor control
- Vapor-permeable; does not act as a vapor retarder
- Common uses
- Interior applications such as sound control and some above-grade cavities in suitable climates
Closed-cell spray foam
What we installClosed-cell spray polyurethane foam (SPF) is a dense, rigid insulation whose cells are almost entirely enclosed. It insulates, air seals and resists moisture in one application, and can add rigidity to the building assembly.
- Appearance
- Cells are closed and tightly packed; cured foam is hard and rigid
- Density
- Typically about 1.75–2 lb/ft³; density varies by product
- Typical R-value
- Typically R-6 to R-7 per inch; use the specific product's published R-value
- Air sealing
- Acts as an air barrier at relatively thin applications (often around 1 inch) with continuous coverage
- Vapor control
- Can qualify as a Class II vapor retarder at sufficient thickness (often around 1.5+ inches)
- Common uses
- Attics, rooflines, exterior walls, basements, rim joists, crawl spaces, garages and metal buildings
Why we install closed-cell in the Capital Region
Albany and the Capital Region have long, cold winters with real freeze-thaw cycles, plus damp basements, crawl spaces and rim joists. Open-cell foam is vapor-permeable and can absorb moisture, so in our climate it carries a higher risk of condensation and moisture problems in rooflines, walls and below-grade areas. Closed-cell foam's higher R-value per inch, vapor resistance and moisture resistance make it the safer, better-performing choice here — which is why it's the only foam we install.
Product, thickness and required protective barriers are chosen using the product's technical data, the building assembly, local climate and code. R-value ranges are typical published values, not a guarantee of performance in your home.
Where does a home lose heat?
Roofline
Roofline insulation follows the underside of the roof deck. In a properly designed unvented assembly, it can bring attic ductwork inside the thermal envelope.
Exterior walls
Spray foam in open exterior wall cavities provides insulation and seals around framing and penetrations, helping limit drafts and unwanted heat transfer.
Basement & rim joists
Foundation walls and rim joists are common insulation and air-sealing targets. The rim is the connection between the floor framing and the foundation.
Crawl space
Crawl-space insulation can help reduce cold floors above. Its placement depends on whether the space is vented or part of a conditioned enclosure.
Garage
Insulating the walls and ceiling of a garage can improve comfort, especially in living spaces above or beside it.
Whole-home heat loss
Heat moves through roofs, walls and foundations, while air leaks carry conditioned air through gaps. A whole-home assessment identifies the most useful improvements.
