What this site is

InsulationPayback reports county-level DOE climate-zone data, recommended attic R-values, and estimated installed cost, annual savings and payback for a typical attic. It is informational only and is not a quote, a home energy audit, or a substitute for an in-person contractor assessment of a specific property.

No warranty on the figures

Every figure traces to DOE, NOAA, or published 2026 contractor-cost and EIA rate data, but actual attic size, access, existing insulation, ductwork, and local labor rates all change the real cost and savings for any one house. Nothing on this site is guaranteed to match what a specific property would actually cost or save, and no result here should be the sole basis for a purchasing decision.

No professional advice

Nothing on this site is engineering, construction, or financial advice. Whether and how to insulate a specific property should be based on an in-person assessment by a licensed contractor or a certified home energy auditor.
