When it comes to the most complete and durable insulation solution available, spray polyurethane foam (SPF) is in a class of its own. AI Greenhome's certified spray foam technicians deliver professional open-cell and closed-cell foam installations that seal your home against air leakage, moisture, and energy loss — permanently.
Spray foam insulation is a two-component liquid that expands on contact to fill and seal every gap, crack, and cavity in your home's envelope. It serves as insulation, air barrier, and vapor barrier in a single application — making it the most comprehensive home performance upgrade available.
Softer, more flexible foam ideal for interior walls, interior attics, and soundproofing applications.
Dense, rigid foam that provides the highest R-value per inch, superior moisture resistance, and structural reinforcement. Ideal for rim joists, crawl spaces, exterior walls, and rooflines.
Expands to fill every crack — no separate air sealing step needed
Closed-cell foam delivers R-6.5 per inch — best in class
Closed-cell foam blocks moisture infiltration and condensation
Does not sag, settle, or compress over time — lasts the life of the home
Closed-cell foam adds rigidity to walls and roof assemblies
Foam does not provide food or habitat for mold, insects, or rodents
The rim joist area (where the floor framing meets the foundation wall) is one of the most common sources of air leakage and heat loss. A few inches of closed-cell foam here delivers immediate, measurable comfort improvements.
Spraying foam directly against the roof deck creates an unvented conditioned attic — dramatically improving HVAC efficiency and eliminating ice dams in winter.
Spray foam on crawl space walls and rim joists encapsulates the space, preventing moisture infiltration and energy loss through the floor above.
Open-cell foam in walls eliminates drafts, reduces noise, and provides continuous insulation coverage behind finished surfaces.
| Feature | Open-Cell | Closed-Cell |
|---|---|---|
| R-Value per inch | R-3.7 | R-6.5 |
| Moisture resistance | Low | Excellent |
| Vapor barrier | No | Yes (2"+ thickness) |
| Soundproofing | Excellent | Good |
| Best for | Interior walls, attics | Rim joists, crawl spaces, exterior walls |
| Cost | Lower | Higher (worth it for moisture-prone areas) |
