Insulation incentives

Get insulation incentives when you insulate a minimum of 20% of the total building component area. For example, 20% of the total ceiling area, regardless of how many different types of ceiling/roof/attic spaces you have. You must provide legible copies of receipts/invoices at the time of the final Home Energy Evaluation. Please see Eligibility Criteria for details in the program guidelines.

*In the tables below, incentive ranges have been minimized to save space. You can still receive incentives for adding insulation amounts between the ranges shown.
