Cambria County, PA Insulation Payback

Attic insulation payback for Cambria County, PA

DOE classifies Cambria County as climate zone 5, cold — a real winter that drives most of the annual energy bill here. Its recommended attic R-value for bare joists is R-60. For an attic around 1,000 square feet, closing the gap from R-2 to R-60 costs around $3,480 and saves an estimated $1,909 a year — payback in roughly 1.8 years. Hard to find a home improvement with a faster payback than this.

Heating vs. cooling in Cambria County

Of that, about $1,862/year comes from reduced heating and $47/year from reduced cooling load through the ceiling. Cambria County beats 78% of the counties in this 3,162-county dataset on estimated insulation savings. Among the 745 counties DOE places in zone 5, Cambria County ranks 139th. Against Pennsylvania's own average of $1,724/year, Cambria County runs 11% above that.

Where these numbers come from

NOAA's EBENSBURG SEWAGE PLT, PA US station, 3.1 miles from Cambria County, supplies the 6,963 HDD and 294 CDD this estimate runs on. That combined heating-and-cooling load ranks Cambria County 763rd nationally by total degree days — the 76th percentile. DOE also classifies Cambria County as moisture regime A (humid) - ask a local contractor whether that changes the vapor-barrier approach for this job.

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 $278/year saved — roughly 8.2 years to break even. It is close - the payback only just fits a reasonable timeframe.

Next steps for a Cambria County attic

Get more than one quote before committing. Attic access and any needed air sealing move the price around, and most contractors won't take a job below roughly $600 regardless of size - worth asking upfront given Cambria County's estimated $1,909/year on the line.
