Dickenson County, VA Insulation Payback

Dickenson County, VA: what topping up your attic actually costs

Dickenson County, Virginia is zone 4 under DOE's climate map (Mixed-Humid), which means a genuine mix of cold winters and humid summers, with neither one dominating the bill. An uninsulated attic there should be built up to R-60. Going from R-2 to the recommended R-60 costs roughly $3,480 installed for a typical attic (about 1,000 sq ft), and pays for itself in about 2.4 years at an estimated $1,479/year saved. That's about as fast as attic paybacks get.

Where the savings come from

The estimated savings split roughly $1,383/year heating, $95/year cooling. Out of every 100 US counties tracked here, Dickenson County's savings potential beats roughly 52 of them. Within zone 4 specifically, it ranks 211th of 825 counties by estimated savings. Virginia averages $1,342/year across the counties tracked here; Dickenson County comes in 10% higher.

The climate data behind this

Dickenson County's climate figures — 5,174 heating and 592 cooling degree days a year — are read from CLINTWOOD 1W, VA US, 7.8 miles away, NOAA's nearest 1991-2020 normals station. By total degree days, Dickenson County sits at the 47th percentile nationally. Dickenson County falls in DOE's moisture regime A (humid), a detail that affects vapor-barrier recommendations more than the R-value target itself.

Already have some insulation?

Already have a few inches up there? Topping R-11 up to R-49 runs about $2,280 for about $216/year saved — roughly 10.6 years to break even. This one is a genuine toss-up, not a clear yes.

Nothing here is a guess

Every figure on this page traces to DOE/IECC climate zones and NOAA degree-day normals, documented in the methodology guide. The guide to what R-value actually means explains why R-60 is the target here specifically.
