Insulation and air sealing

To maximize your energy savings consider installing insulation.  Insulation levels are specified by R-Value.  The higher the R-Value, the better its thermal performance. Note: A Small Business Energy Assessment must be completed prior to installation to qualify for insulation rebates.

Varies

Insulation and air sealing
Alliant Energy offers a rebate for each key area you insulate in your business. And since air sealing should also be done when you insulate, you can receive an additional rebate up to $1,500 for air sealing projects.

Benefits of insulating and air sealing:
- Business spaces become more comfortable, durable and energy efficient
- Reduced energy bills
- Helps address moisture and mold issues
- Reduces outside noise

Insulation is rated by R-value, which measures resistance to heat flow. The higher the R-value, the more insulating power. Different R-values are recommended for attics, ceilings, walls and pipes, etc. You can find out your current and ideal R-values by completing a free energy assessment offered by Alliant Energy.

How do I apply?
Start by scheduling a Small Business Energy Assessment to determine the amount of insulation required. It’s a simple process that works with you and your schedule. After your assessment, we can help you find a contractor or you can insulate and air seal yourself.

Important information:
Insulation rebates are calculated based on the cost per R-value per square foot of conventional insulation materials (e.g. blown-in loose-fill, blanket rolls or batts.) No additional rebate is awarded for more expensive alternative insulation materials such as spray foam..

How do I find a qualified dealer?
Visit our online Dealer Locator to find a professional in your area. Or, you can do the projects yourself after you’ve had your energy assessment.
