Insulation

Why you should upgrade your insulation

Upgrading your insulation can make your home more energy efficient and comfortable. It can also save you money. If your home has electric heat, upgrading to current insulation standards could reduce your utility bills significantly for years to come.

Properly installed insulation helps stop cold air drafts, holds heat inside, and reduces outside noise.

To get the full value from insulation and air sealing, it must be installed properly. Insulation must be placed in the right location and installed without leaving gaps that reduce the performance of the insulation.

Incentives we offer for insulation

We offer three incentives to help you pay for upgrading your insulation in your crawlspace, walls, and attic. Choose one of these:
