Spray foam insulation numbers here are 2026 planning ranges, adjusted per city — useful for budgeting, not a substitute for an actual quote.
Is the gap worth worrying about?
That 1% gap is small — for spray foam insulation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.
Spray foam insulation by type: Roswell vs Savannah
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.
| Type | Roswell | Savannah |
|---|---|---|
| Open-cell | $1,450–$4,400 | $1,500–$4,500 |
| Closed-cell | $2,450–$6,900 | $2,500–$7,000 |

Spray foam insulation by area: Roswell vs Savannah
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 | Roswell | Savannah |
|---|---|---|
| 500 sq ft | $900–$2,350 | $900–$2,400 |
| 1,000 sq ft | $1,450–$3,950 | $1,500–$4,000 |
| 1,500 sq ft | $2,150–$5,400 | $2,200–$5,500 |
| 2,000+ sq ft | $2,750–$6,400 | $2,800–$6,500 |

Cheapest time for spray foam insulation in either city
Demand for insulation spikes every fall as winter approaches, pushing prices with it. Spring and summer avoid that crowd, and utility rebate pools are frequently still fresh that early in the year.
How much insulation is worth paying for?
How much you spend on insulation and how fast it pays back come down to R-value, air-sealing and material. Our editors break down the trade-offs.
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.
The air-sealing case
Insulation without air-sealing underperforms. Sealing leaks first is cheap and often delivers more comfort per dollar than thicker insulation alone — make sure it's in the scope.
Payback is the whole point with insulation, and it arrives fastest when the job is done in full: air-sealing, the DOE-recommended R-value for your climate zone, and whatever utility rebates you qualify for. Trimming any one of those trims the return, not the cost.

Should I choose where to live based on spray foam insulation cost?
Rarely. The $50 difference is real but one-time, and you can often close most of it in Savannah by buying in the off-season and getting tighter, apples-to-apples bids. Ongoing factors — energy prices, climate and home condition — matter more over the life of the system.
