How much insulation West Virginia actually needs

Mixed climates recommend roughly R-38 to R-60 in the attic — enough to hold heat in winter and keep cooling in through summer.

Rebates & incentives
Insulation and air-sealing lost their federal tax credit in 2026, but rebates and free-weatherization programs still cut the cost — especially for lower-income households.
- The federal 25C tax credit (which covered up to $1,200/yr of insulation and air-sealing) ended December 31, 2025 under the One Big Beautiful Bill Act — not available for 2026.
- IRA Home Electrification & Appliance Rebates (HEAR): up to $1,600 toward insulation, air-sealing and ventilation for households under 150% of area median income, where the state program has launched.
- IRA HOMES rebates: up to $8,000 for whole-home efficiency retrofits that hit modeled energy-savings targets.
- Weatherization Assistance Program (WAP): free insulation and air-sealing for households at or below 200% of the federal poverty level.
- Many gas and electric utilities offer their own insulation rebates — check the DSIRE database and your provider.
