Protect your home by sealing leaks and adding insulation—that’s what weatherization is all about. Proper insulation prevents heat loss and reduces the amount of heating and cooling you need to remain comfortable all year long.
Should You Invest in More Insulation?
Currently, all new homes are required to have R-49 insulation in the ceiling (13 inches of cellulose insulation or 20 inches of fiberglass insulation) and R-30 insulation in the floor (a 10-inch batt of insulation) over unconditioned space.
How much more insulation you need depends on the cost of the fuel you use to heat your home. From a purely financial standpoint, the less you pay for heating fuel, the less it makes sense for you to invest in more insulation. For example, homes that were built in the 1960s and 1970s had little insulation because the cost of fuel didn’t justify much of an investment in insulation. As heating costs increase, it makes more financial sense to increase insulation.

Rebates for Existing and Manufactured Homes
Our rebate program reimburses a portion of your weatherization expenses. To qualify for rebates, the weatherization work must be done by a contractor participating in our Contractor Network.
Income Qualified Rebate Program
We offer rebates to eligible Clark Public Utilities customers making floor, attic, and wall insulation upgrades. Eligibility is limited to customers living in single-family households or manufactured homes that have a Clark Public Utilities electric account, currently have qualifying electric space heat, and have an annual gross household income under 80% Area Median Income (AMI).
Multi-family Property Programs
We offer a variety of rebates for owners of electrically heated multi-family buildings (five or more dwelling units) in Clark County. Buildings must also have dwelling units that are stacked, meaning the units share floor and ceiling areas. Please see our multi-family property programs page for more information.
Your energy savings and project costs will vary. Program requirements and rebate amounts are subject to change without notice. We do not endorse any particular contractor, manufacturer or product. We make no express or implied warranties of these products or installations. There are limits to rebates and grants (when available).
*“U-factor” is an efficiency measurement: the lower the number, the more energy-efficient the window will be. Windows must be installed in a conditioned space.
