Save energy by improving your attic insulation

Insulation helps keep your home cool in the summer and warm in the winter. There are several common types of insulation, such as fiberglass (in batt, blanket and blown forms), cellulose, rigid foam board and spray foam. Insulation performance is measured by R-value - its ability to resist heat flow. Higher R-values mean more insulating power.

SRP recommends minimum insulation levels of R-19 for exterior walls (total wall system) and R-38 for ceilings.

Insulation rebate

For insulation to be effective, it must be installed properly in the right locations and be free of gaps, voids and compressions. When combined with sealed air leaks, properly installed insulation provides for more even temperatures throughout the house—resulting in a quieter, more comfortable home. It can also help you save about 10% on cooling and heating costs.*

Rebate offer: 75% off the insulation cost (up to $600), when installed by a participating contractor. The rebate will be applied as an instant discount on the contractor’s invoice.

Eligibility requirements: This insulation rebate applies only to attics and is based on the improvement of the insulation's R-value.

  • Existing insulation with an effective R-value less than R-19 that is improved to R-38 can qualify for a rebate.
  • Be a current SRP residential electric customer (new construction does not qualify) who resides in a single-family detached home, single-family attached home or apartment/condo. Mobile homes are not eligible.
  • Insulation greater than R-19 but performing under this value may qualify for a rebate to improve insulation up to R-38. Evidence of underperformance (e.g., photos and thermal images) and an explanation must accompany the rebate form.
  • Your Insulation improvements must be performed by a participating BPI-certified professional who is licensed in Arizona and listed on the SRP list of available contractors in the Insulation program.

Insulation improvements must be made in combination with air sealing unless documentation proves air sealing is unnecessary. All materials and installation processes must meet BPI building analyst standards.
