Commercial Insulation

Rebate amounts and program requirements are subject to change without notice. All homes or businesses are subject to inspection and usage data analyzed by participating in energy efficiency programs. Any rebates will be applied to past due amounts owed CPI before payment is issued.

CPI offers a commercial insulation incentive that is based on precondition wall, roof and attic levels with very little (defined as R-0 to R-5) insulation value. The building(s) must be electrically heated.

Attic insulation is defined by insulation that is installed in the attic crawl space, typically on a horizontal surface. Roof insulation is defined by insulation that is installed in direct contact with the building’s roof, typically a flat or slightly pitched surface.
