Spray foam insulation numbers here are 2026 planning ranges, adjusted per city — useful for budgeting, not a substitute for an actual quote.
How much should this gap actually matter?
A 16% gap is meaningful on a project this size — about $600. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in San Francisco.
Spray foam insulation by type: Cheyenne vs San Francisco
Every spray foam insulation type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.

Spray foam insulation by area: Cheyenne vs San Francisco
Spray foam is priced by board foot (1 sq ft at 1 inch thick), which works out to about $1.50–$5 per sq ft of surface installed depending on foam type and thickness. Closed-cell costs more but adds twice the R-value per inch.
| Size | Cheyenne | San Francisco |
|---|---|---|
| 500 sq ft | $900–$2,450 | $1,050–$2,850 |
| 1,000 sq ft | $1,550–$4,100 | $1,800–$4,750 |
| 1,500 sq ft | $2,250–$5,650 | $2,600–$6,500 |
| 2,000+ sq ft | $2,850–$6,650 | $3,300–$7,700 |

Cheapest time for spray foam insulation in either city
Fall is when everyone rushes to insulate before winter hits, making it the busiest and priciest season. Spring and summer see far less demand — and utility rebate budgets are often still full that early in the year.
How much insulation is worth paying for?
Where an insulation budget lands depends less on square footage than on three calls — the R-value you target, whether air-sealing rides along, and which material fills the cavity.
The air-sealing case
Skip air-sealing and you're insulating around the very holes letting conditioned air leak out. Caulk, foam and weatherstripping are inexpensive and often return more felt comfort than a thicker blanket of insulation ever would — insist the crew handles the leaks before they bury them.
The rebate case
Few home projects come with rebate support like insulation does — utility and state programs routinely offset a meaningful slice of the bill (the federal 25C credit closed in December 2025). Run your address through DSIRE first, and book when a program's yearly budget has just refilled.
The R-value case
Aim for the R-value the DOE assigns your zone, not a round number that sounds close enough. Every point you fall short is comfort you don't feel and utility savings you never bank — savings that would have covered the extra material several times over.
Hit the DOE R-value for your zone, air-seal first, and stack the rebates. Insulation is one of the few upgrades where doing it fully is also the cheapest path to payback.
