Spray Foam Cost Estimator

Cost is driven by foam chemistry (open-cell vs. closed-cell), total board footage, required thickness to meet target R-value, and site access conditions. Open-cell ranges from $0.50–0.65/board foot, typically applied at 3.5–5.5 inches to achieve R-13 through R-20. Closed-cell ranges from $1.15–1.35/board foot and reaches R-13 at just 2 inches of applied thickness. Residential projects generally fall between $1,500 and $4,000. Elite Spray Foam Kokomo provides itemized quotes broken out by material, labor, and prep based on your project specifications.

Elite Spray Foam Kokomo has completed insulation projects spanning metal buildings, pole barns, warehouses, manufacturing facilities, cold-storage environments, multi-unit residential, office retrofits, and ground-up commercial construction. We work from architectural specs and coordinate with GCs and project managers on sequencing, vapor profile requirements, and fire-rating compliance. Commercial and industrial envelopes typically present higher infiltration rates due to larger penetration counts and unsealed metal panel joints. Spray foam addresses both thermal performance and air barrier continuity in a single application.

A standard residential cavity (attic, crawl space, or rim joist) runs 4–6 hours including masking, multi-pass application, thickness verification with depth gauges, trimming, and cleanup. Whole-home projects typically complete in 1–2 days. Larger commercial applications with 5,000+ square feet of coverage may require 2–3 days to allow for proper lift scheduling and curing between passes. We provide a detailed project timeline based on measured square footage and target R-values.

All surfaces outside the spray zone are masked with 6-mil poly sheeting and blue painter's tape. HVAC registers, electrical panels, and finished surfaces are sealed off to prevent overspray contact. The two-component foam reaches tack-free cure within 8–10 seconds of leaving the gun, which limits aerosol drift. Excess material is trimmed flush to the stud face using a reciprocating saw with a foam-cutting blade. We perform a walkthrough inspection and full debris removal before clearing the site.

Open-cell (0.5 lb/ft3 density) delivers R-3.6 per inch and is vapor-open — typically 10–16 perms at 3.5 inches installed thickness. Suited for interior cavities where drying potential to the interior is desirable. Closed-cell (2.0 lb/ft3 density) delivers R-6.5 per inch, functions as a Class II vapor retarder below 1.5 inches and a vapor barrier above 2 inches, and contributes racking strength to framed walls. Material selection depends on the assembly's vapor profile, required R-value, structural loading, and moisture exposure. We specify based on the building science of each application.

All installations carry a workmanship guarantee covering application quality, adhesion, and specified thickness. The underlying material performance is indefinite. Spray polyurethane foam does not lose R-value over time because its cellular structure is dimensionally stable. It does not absorb moisture, support mold growth, or compress under its own weight the way fibrous insulation does. In practice, the foam outlasts every other building component it contacts.
