Climate zone 6A: what it means for spray foam
Utica's central point is in Oneida County, which the 2021 IECC county map assigns to climate zone 6A (cold in DOE's Building America terms). Zone 6A is a moist ("A") zone, which drives the vapor and R-value rules below.
Other counties within our Utica service radius: Herkimer County (6A), Madison County (6A), Otsego County (6A). All are zone 6A too.

Open cell vs closed cell in Utica, NY
Attic roofline: in zone 6A, IRC Section R806.5 requires that air-impermeable insulation under an unvented roof deck either be a Class II vapor retarder itself or be covered with a vapor-retarder coating. Closed-cell foam meets that on its own at typical thicknesses; open-cell foam needs vapor-retarder paint. In a hybrid assembly the foam layer at the deck must be at least R-25.
Rim joists and basement walls are where spray foam pays off fastest in cold climates: closed cell air-seals the leaky band joist and blocks moisture in one pass, which is hard to do with batts.
How much insulation to ask for
| Where | ENERGY STAR recommendation for zone 6A |
|---|---|
| Attic, uninsulated | R-60 |
| Attic with 3–4" of existing insulation | add R-49 |
| Floor over unconditioned crawlspace/basement | R-30 |
| Basement or crawlspace walls | R-15 continuous or R-19 cavity |
| Exterior walls (when re-siding) | add R-5 to R-10 insulative wall sheathing beneath new siding |
To reach R-60 with foam alone you'd need roughly 16.2–17.1" of open cell (about R-3.5 to R-3.7 per inch) or 8.6–12.0" of closed cell (about R-5 to R-7 per inch). Many roofline spray foam jobs are installed thinner than that and justified through the code's performance path or the unvented-attic rules, so ask every installer to write the foam type, thickness and resulting R-value on the quote and explain how it meets your local code.

New York energy code
2024 IECC with New York amendments, effective December 31, 2025. New York largely applies climate zone 6 prescriptive requirements in zones 4 and 5 as well, making it one of the stricter codes in the country.

Homes in Utica, NY
Census figures for Utica city (ACS 2020–2024 5-year estimates): about 28,364 housing units, a median year built of 1940, 87% built before 1980 and 3% built in 2010 or later. 43% are single-family detached homes and 0% are mobile/manufactured homes. 50% of occupied homes are owner-occupied, with a median owner-reported home value of $151,300.
- With 87% of homes built before 1980, many attics here predate modern energy codes. Older attics often need old insulation removed or air-sealed first, and knob-and-tube wiring must be checked before any insulation covers it. Ask whether removal and prep are in the price.
- 75% of homes heat with utility gas. Spray foam makes a house much tighter, which changes how gas furnaces, water heaters and fireplaces draft, so ask whether the installer (or your HVAC contractor) will do combustion safety testing after the job. Some utility rebates require it.
