Three local examples
- Erie attic, 1,200 sq ft, blown-in cellulose added on top of about 3 to 4 inches (R-49 more, about R-60 in all): $1,290–2,230.
- 40×60 pole barn roof, 2 inches of closed-cell (about 5,060 board feet): $6,320–9,490.
- Two-story house, 2,060 sq ft of open 2×6 wall after windows and doors, 3 inches of closed-cell: $7,730–11,590.
How these are set: closed-cell spray foam sits midway between the national cost guides ($1.00–1.50 per board foot) and FoamGuard’s published price ($1.50–2.25). Every other type uses the national range.

Insulation cost per square foot, by type (U.S.)
National installed ranges for a normal job with easy access, as of October 30, 2026. Thicker insulation and harder access cost more; the calculator above adjusts for both.
| Insulation | Installed (U.S.), per sq ft | Best for |
|---|---|---|
| Fiberglass batts | $0.46–0.84 at R-13; $0.74–1.36 at R-21 | Open walls, floors, attic floors |
| Mineral wool batts | $0.90–1.43 at R-15; $1.38–2.19 at R-23 | Fire resistance, quieter rooms |
| Blown-in fiberglass | $1.23–1.96 adding R-49 | Attic floors; netted or drilled walls |
| Blown-in cellulose | $1.08–1.86 adding R-49; $1.32–2.28 for R-60 in an empty attic | Attic floors |
| Dense-pack cellulose | $1.04–1.69 at R-13; $1.68–2.73 at R-21 | Finished walls, drilled and patched |
| Rigid foam board | $1.20–3.00 at R-10; $1.80–4.50 at R-15 | Basement and crawl space walls |
| Open-cell spray foam | $0.44–0.65 per board ft; $2.42–3.58 at 5½ in. | Air sealing walls; needs vapor control in zones 5–8 |
| Closed-cell spray foam | $1.00–1.50 per board ft; $3.00–4.50 at 3 in. | Rim joists, basements, metal buildings, roof decks |
| Removing old insulation | $1.00–2.00 per sq ft | Old insulation that is wet, packed down or damaged |
Key points
- You pay for the area that gets insulation. Windows, doors and garage doors come out first.
- Batts, blown-in and board are priced by the R-value you add; spray foam by the board foot (square feet × inches).
- On an open, vented attic floor, blown-in insulation reaches R-60 for a fraction of what foam costs.
- Spray foam costs more because it also seals air leaks, and closed-cell also slows vapor.
- Removing old insulation adds about $1 to $2 per square foot.
How the calculator works
- Area. Length × height for each wall, or length × width for floors and roofs. Gable ends count as triangles. Roof decks use the slope, so a 6/12 roof has about 12% more surface than its floor plan.
- Openings. Every window and door you enter comes out, at the sizes in the table below. Use “Other opening” for anything else.
- Prices. Low and high installed prices come from three national cost guides (Angi, Fixr and HomeGuide, 2026). For batts, blown-in and board, each range is turned into a price per R-value per square foot, so adding more R costs more. Spray foam is priced per board foot. The middle of each range is shown as typical.
- Western PA and Eastern Ohio. In FoamGuard’s service area, closed-cell spray foam is priced midway between the national guides ($1.00–1.50 per board foot) and FoamGuard’s published price ($1.50–2.25): $1.25–1.88. Every other type uses the national range.
- Attic amounts. How much to add comes from ENERGY STAR’s recommendations by climate zone: in zones 4 to 8, about R-60 in an empty attic, or R-49 added on top of 3 to 4 inches. Your zone is a best guess from your ZIP code’s state; change it if yours is different.
- Not included. Removing old insulation (unless you tick it for the attic), drywall or patching, ignition or thermal barrier coatings where code calls for them, permits, travel and small-job minimums.
- Updates. The prices are checked every three months. The date at the top changes only when a number changes.
Default opening sizes
| Opening | Size | Taken out |
|---|---|---|
| Window | 36 × 60 in | 15 sq ft |
| Entry door | 36 × 80 in | 20 sq ft |
| Patio door | 72 × 80 in | 40 sq ft |
| Single garage door | 9 × 7 ft | 63 sq ft |
| Double garage door | 16 × 7 ft | 112 sq ft |
| Overhead door | 12 × 12 ft | 144 sq ft |
| Walk door | 36 × 80 in | 20 sq ft |
How much attic insulation to add, by climate zone
| Climate zone | Attic has none: add | Attic has 3 to 4 inches: add |
|---|---|---|
| 1 | R-30 | R-25 |
| 2 and 3 | R-49 | R-38 |
| 4 to 8 | R-60 | R-49 |
From ENERGY STAR’s recommended levels for existing wood-framed homes (“Add Insulation to Attic”, based on the 2021 energy code). With 3 to 4 inches already there (about R-11), adding R-49 ends near R-60.

FAQ
How much does it cost to insulate a 2,000 sq ft house?
It depends on what you insulate. Topping up a 1,000 sq ft attic that has 3 to 4 inches with blown-in cellulose (adding R-49) runs about $1,080–1,860. Filling about 2,200 sq ft of open 2×4 wall with R-13 fiberglass batts runs about $1,000–1,860, and with 2 inches of closed-cell spray foam about $4,400–6,600 at national prices. Enter your own walls and attic above for your number.
How much does it cost to spray foam a pole barn in Western PA?
At the Western PA and Eastern Ohio market range of $1.25–1.88 per board foot, 2 inches of closed-cell under a 40×60 roof (about 5,060 board feet) runs about $6,320–9,490. Add 14-foot walls and the gable ends (about 11,193 board feet in all) and the building comes to about $14,000–21,000 before doors are taken out. FoamGuard’s own price is $1.50–2.25 per board foot; see what a 30×40 or 40×60 pole barn costs.
How much attic insulation do I need in Pennsylvania?
Most of Pennsylvania is climate zone 5 and the Philadelphia area is zone 4. ENERGY STAR’s recommendation is the same for both: about R-60 in an attic with no insulation, or R-49 added on top of 3 to 4 inches, which ends up near R-60 too.
Do I subtract windows and doors?
Yes. You pay for the area that gets insulation. A typical window takes out about 15 sq ft, an entry door 20 and a double garage door 112. On a two-story house that is often 10 to 15 percent of the wall.
Is spray foam worth the extra cost?
Sometimes. It seals air leaks as it insulates, and closed-cell also slows vapor, which matters on rim joists, basement walls, metal buildings and roof decks. On an open, vented attic floor, blown-in insulation reaches the same R-value for a fraction of the price.
Why is my quote higher than the calculator?
Access, prep, removing old insulation, coatings, permits and small-job minimums all add cost, and so do thicker layers. Ask every installer for the product, the thickness, the R-value and the square feet (and board feet for foam) in writing, so you can compare quotes line by line.
Is the calculator really free?
Yes. No sign-up, no email, no phone number. FoamGuard installs spray foam in Western PA and Eastern Ohio, and built the calculator so anyone can get an honest range before calling anyone.
