Thermal Envelope Improvements

You must use a professional contractor and you must receive pre-approval from CFU for thermal envelope improvements (exceptions noted below). CFU will pay incentives on residential attic insulation provided that the existing insulation level is less than R-40. Homes with R-40 or higher insulation levels will see little return on the investment in additional attic insulation. Rebates applications may be submitted for projects that increase the attic insulation up to a maximum of R-60.

You can use any licensed contractor to qualify for CFU's air sealing and insulation incentives.
