Benefits of Spray Foam Insulation

Spray foam insulation delivers multiple advantages over fiberglass or cellulose:

  • Superior R-Value: Open-cell (~R-3.7/inch) and closed-cell (~R-6.5/inch) configurations for maximum thermal resistance (Spray Foam Advisor).
  • Air Sealing: Fills gaps, cracks, and penetrations to prevent drafts and air leakage (AirSealing.org).
  • Moisture Barrier: Closed-cell foam acts as a vapor barrier, preventing mold and moisture issues in Cary’s humid climate.
  • Sound Dampening: Reduces noise transmission between rooms and from outside.
  • Longevity: Does not settle or degrade over time like loose-fill materials (Building Science Digest).

Types of Spray Foam

Open-Cell Spray Foam

Lightweight, soft, and flexible. Best for interior walls and attics where moisture control is secondary (Insulation Institute).

Closed-Cell Spray Foam

Denser and rigid, with higher structural strength and vapor resistance. Ideal for crawlspaces, basements, and exterior insulated sheathing (Spray Foam Magazine).

Applications in Cary Homes

Attic Insulation

Upgrade existing fiberglass with spray foam for dramatic reduction in heat gain/loss—see our Attic Insulation page.

Wall Insulation

Retrofit walls using injection open-cell foam—refer to Wall Insulation techniques.

Crawlspaces & Basements

Seal and insulate rim joists and foundation walls with closed-cell foam—learn more on our Blow-In Insulation page.

Eco-Friendly Builds

Cost and ROI

Installed costs in Cary range:

  • Open-cell: $1.00–$1.50 per board foot
  • Closed-cell: $1.50–$3.00 per board foot (ANGI)

Energy savings often pay back initial investment within 3–5 years, based on local energy rates and house tightness (HomeAdvisor).

Choosing the Right Contractor

Ensure your contractor is certified by:

  • Spray Polyurethane Foam Alliance (SPFA)
  • Building Performance Institute (BPI)
  • Local licensing and insurance

Review case studies on Spray Foam Garner and Spray Foam Apex for workmanship examples.

Environmental Considerations

Closed-cell foams use HFC or HFO blowing agents—opt for low-GWP options. Pair with air sealing and efficient HVAC to maximize sustainability (NREL).
