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.

Getting Started

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 daysof 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.

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!

Available Incentives

Installed Insulation	Electrically Heated Homes Incentive	Electrically Cooled Homes Incentive
Attic Insulation	$0.30 sq/ft	$0.15 sq/ft

Floor Insulation	$0.25 sq/ft	N/A
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.

Qualifications

For all insulation projects

• Attic and wall insulation: Home must have an electric heating system or electric cooling system serving at least 80 percent of the floor area
• Floor insulation: Home must have an electric heating system serving at least 80 percent of the floor area. Electric cooling is not sufficient to meet the requirement for a floor insulation incentive

Definitions:

• Electric heating is defined as permanently installed ducted electric furnaces, heat pumps or electric zonal heating systems (baseboard or cadet wall heaters)
• Electric cooling is defined as permanently installed ducted electric central air conditioning or heat pump system
• Work performed as part of building code requirements is not eligible for an incentive. Additionally, areas that are not finished or conditioned living spaces (permanently installed heating or ducted cooling), such as a garage or basement, do not qualify.
• Homes built less than one calendar year prior to the work being performed do not qualify for the incentive
• Incentive application and required documents must be received within 90 days of the completed service

Attic insulation

• Pre-existing insulation levels must be equal to or less than R-20
• New insulation added must be equal to or greater than R-19
• Final insulation depth must be R-38 or greater

Floor insulation

• Home must have an electric heating system serving at least 80 percent of the floor area. Electric cooling is not sufficient to meet the requirement for a floor insulation incentive
• Pre-existing insulation levels must be equal to or less than R-18
• New insulation added must be equal to or greater than R-19
• Floor insulation must be installed between conditioned and unconditioned space in order to qualify for incentives (if your basement is ducted for heating/cooling, you do not qualify for floor incentives)

Wall insulation

• Pre-existing insulation levels must be equal to or less than R-10
• New insulation added must be equal to R-11or must fill cavity
• Only exterior-facing walls qualify
• Basements must be finished or conditioned living space (permanently installed heating or ducted for cooling) in order to qualify for wall insulation
