Hudson County, NJ Insulation Payback
Hudson County attic insulation, by the numbers
DOE classifies Hudson County as climate zone 4, mixed-humid — a genuine mix of cold winters and humid summers, with neither one dominating the bill. Its recommended attic R-value for bare joists is R-60. Topping up a typical 1,000-square-foot attic from bare joists (R-2) to R-60 runs an estimated $3,480, and saves about $1,505 a year in heating and cooling — a payback around 2.3 years. Topping up the attic pays for itself fast here.
Heating vs. cooling in Hudson County
Split it out and it's roughly $1,309 a year on the heating side, $196 on cooling. By estimated insulation savings, Hudson County lands in the 53th percentile nationally. Zone 4 alone covers 825 counties in this dataset, and Hudson County comes in 167th by savings. New Jersey averages $1,541/year across the counties tracked here; Hudson County comes in 2% lower.
The climate data behind this
NOAA's HARRISON, NJ US station, 4 miles from Hudson County, supplies the 4,896 HDD and 1,219 CDD this estimate runs on. That combined heating-and-cooling load ranks Hudson County 1445th nationally by total degree days — the 54th percentile. One local detail the R-value alone won't tell you: Hudson County sits in moisture regime A (humid), which can affect the vapor-barrier choice.
If the attic isn't bare
Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $220/year saved — roughly 10.4 years to break even. Call this borderline rather than a clear win.
Getting it done in Hudson County
Real bids depend on how easy the attic is to reach and whether old insulation needs removing first, so treat $3,480 as a starting estimate for a Hudson County job, not a quote. Expect at least a $600 minimum charge from most contractors.
Where these figures come from
Hudson County's R-60 target and its degree-day figures both come from named federal sources - see the methodology guide for exactly which ones. The guide to what R-value actually means explains why R-60 is the target here specifically.
