Insulation & Air Sealing Rebates

The cooperative now offers rebates to members who install qualified insulation and/or air sealing upgrades in their home. By reducing the amount of air that leaks through the home's envelope, members can save money on their home’s energy costs and increase their home's comfort level. Find out about insulation and air sealing incentives offered below. 

Importance of Insulation & Air Sealing

Homes should be an oasis for all of us - a place to kick back and get comfortable. But there's no oasis of comfort when a home is too cold in winter or oppressively hot in the summer. That means it’s leaking air—and wasting money.

Air infiltration (or air penetration through the home's "envelope") is one of the main problems facing most homes. One of simplest ways to reduce your home’s heating and cooling costs– and improve comfort– involves installing proper insulation and air sealing. Doing so provides resistance to heat flow. The more heat flow resistance your insulation and air sealing provides, the lower your heating and cooling costs.

Heat flows naturally from a warmer to a cooler space. In winter, heat moves directly from heated living spaces to adjacent unheated attics, garages, basements, and even outdoors. It can also travel indirectly through interior ceilings, walls, and floors—wherever there is a difference in temperature. During the summer cooling season, the reverse takes place. Heat flows from the outdoors to the interior of a house.

To maintain comfort, heat lost in the winter must be replaced by your heating system. In summer, heat gained must be removed by your cooling system. Proper insulation and air sealing, though, decreases heat flow and reduces energy consumption and heating and cooling costs.

Adding insulation to your home? An R-value indicates insulation’s resistance to heat flow—a higher R-value means more effective insulation. Every type of insulation has a unique R-value depending on material, thickness, and density. Your ideal R-value depends on whether your home is new or existing, your heating fuel, and where you live.

Program Qualifications

All qualifying insulation and air sealing upgrades must be installed in a primary electrically heated residential home. Seasonal homes do not qualify.

Effective Program Dates

July 1, 2016 through June 30, 2017

Program Eligibility
  • Insulation and air sealing upgrades must be installed by a licensed and insured contractor. Do-it-yourself projects are not eligible for this rebate.
  • Applicant must own the home and be the homeowner of record.
  • Only one rebate is permitted per household.
  • Projects must be a retrofit installation in an existing residential home. Program is not applicable for new construction or room/home additions.
  • Rebate is for exterior house, exterior basement or crawlspace walls, attic insulation or air sealing upgrades only. Installations not eligible for a rebate include: new construction, new residential additions, garages, sheds, workshops, insulating doors, sound proofing applications, properties with more than two units or product replacement for air sealing (e.g. replacing doors, windows, lighting fixtures, etc.).
  • All projects must comply with applicable federal, state and local laws and building codes.
  • All applications must be complete and include an itemized contractor invoice detailing cost breakout for each area of work/improvement made in order to be considered. Incomplete applications will not be processed.

Insulation or air sealing installed with funding (or applicable for a rebate) from another non-cooperative utility incentive program are not eligible for this program.

Conditions of Rebate
  • For insulation rebate, contractor must follow Energy Star® guidelines and achieve minimum R-16 for exterior house walls, R-38 for attic, R-10 for exterior basement walls, R-10 for crawlspace walls (installation of minimum 6-mil poly on floor is required; use of foam insulation is encouraged) and/or R-6 for ducts.
  • For air sealing rebate, contractor must follow Energy Star® guidelines and perform required duct blast and/or blower door test. Final test results after duct sealing must achieve less than or equal to 12CFM25 per 100 sq. ft. (for both conditioned and unconditioned space) to be eligible for rebate. Final test results after air sealing upgrade must achieve less than 4,000 CFM50 to be eligible for rebate. Installation of exterior basement wall insulation and/or crawlspace wall insulation (with 6-mil poly) is considered an insulation rebate and not an air sealing rebate.
  • The cooperative reserves the right to inspect the home for installation of materials listed on the rebate application to verify that installation meets program guidelines.
  • Application and all required documentation must be submitted to Butler Rural Electric Cooperative no later than June 30, 2017.
