Bundle up your home to save money and significantly increase comfort.
Designed to keep your home warm in the winter and cool in the summer, properly installed insulation can significantly lower your electricity bill. There are several common types of insulation – fiberglass, cellulose, rigid foam board and spray foam – all of which can help you save electricity and money. When adding insulation, make sure you know the R-value of the product you are considering. Used to measure the insulation's thermal performance, a higher R-value will deliver more insulating power.

Energy Saving Benefits
- Use less electricity for heating and cooling by reducing heat transfer in and out of your house
- Save money by using less electricity to maintain a comfortable temperature in your home
Avoid greenhouse gas emissions by using less electricity to maintain the temperature of your home
Insulation may be self-installed by homeowners or installed by a contractor. Customers interested in using a contractor can find a participating contractor using the Idaho Participating Weatherization Contractors list. When choosing to use a contractor, review the Incentive Application with them to determine eligibility requirements, incentive qualifications and review the list of required documents to submit for an incentive.
Incentive Application and required documents must be received within 90 days of the completed service (the date the work is completed). Insulation must be fully installed prior to submitting an Incentive Application. Incentive checks are issued within 45 days of receipt of the completed and approved Incentive Application. Checks are only payable to the account holder or property. Incentives are not to exceed the project cost and are limited to the square footage of the qualified area of the home (wall, floor or attic). Work may be inspected for compliance. Incentives are subject to tariff approval and may change with 45 days notice. Additional terms and conditions may apply.
Self-installers are eligible for incentives on materials only and documentation of R-values and square footage must be provided. This information will be listed on the register receipt or insulation packaging.
For work completed on or before August 19, 2012: There is a $350 cap for all insulation incentives (total incentive amount for attic, floor, wall combined at one home will not exceed $350) for the life of the home.
To ensure your home is eligible for an incentive and below the maximum insulation depth requirements, please use the insulation depth calculator. Prior to your contractor recording measurements, take a peek in your attic and do it yourself!

- Home must have an electric heating system or an electric cooling system serving at least 80 percent of the home’s conditioned floor area.
- Electrically heated home incentives apply to houses with a permanently installed electric furnace, heat pump or electric zonal heating systems (baseboard or ceiling/wall heaters). Space heaters do not qualify.
- Homes with an electric heating system and a central air conditioner only qualify for the “Electrically heated home” incentives.
- Electrically cooled home incentives apply to houses with a permanently installed ducted electric central air conditioner and a non-electric (gas, oil or propane) heating system.
- Contractor-installed and self-installed work must be performed in accordance with the Idaho Weatherization Installation Checklist in Attachment B.
- For self-installers: projects will be paid on materials only. (Note: Wall insulation is not eligible for self-install)
- For multi-family applications only: provide a copy of completed W-9, if applicable.
- Insulation must be installed between conditioned and unconditioned space in order to qualify for incentives.
- A finished or conditioned living space has a permanently installed heating or ducted cooling system.
- Unconditioned spaces exist outside of the home’s thermal boundary (e.g., garages, crawlspaces, the exterior of a home, and potentially a basement).
- Insulation incentives are available on existing homes only. Work performed as part of building code requirements is not eligible for an incentive.
