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

Environmental Benefits

Avoid greenhouse gas emissions by using less electricity to maintain the temperature of your home

Getting Started

Insulation may be self-installed by homeowners or installed by a trade ally. Customers interested in using a trade ally can find a participating trade ally using the Wyoming Weatherization Program Trade Allies list. When choosing to use a trade ally, 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 postmarked within 90 days of the work completed date. Incentive checks are issued within 45 days of receipt of the completed and approved incentive application. Checks are only payable to the account holder. Incentives are not to exceed the project cost. 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.

To ensure your home is eligible for an incentive and meets the existing 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!
