Any air that leaks out of your home is money leaving your pocketbook. One of the most cost-efficient ways to save money on energy is insulation. For new builds or existing homes, insulation is an easy means to combat hot, humid Midwestern summers and frosty winters. At the nearest, you can find the insulation that best suits your needs. Then, to find a contractor to install it, check out our Find-A-Contractor tool.

The Best Insulation for Your Home

In Midwestern homes especially, adding glass mineral wool insulation above minimum building requirements significantly increases energy savings. Talk with an insulation expert about which type of insulation is right for your home:


Glass mineral wool blanket insulation is packaged in batts, or rolls, and comes in a variety of thicknesses, widths, lengths and “R-values”—the higher the R-value, the greater the insulating effectiveness.

Batts & Rolls

Batts are most commonly installed in homes’ sidewalls, attics, floors, crawl spaces, cathedral ceilings and basements.

Loose Fill

Glass mineral wool loose-fill insulation consists of individual bits designed to be blown into attic spaces or other areas of the home that are hard to access with blanket insulation.


 Insulated Sheathing combines OSB structural sheathing with continuous insulation for faster installation to provide protection against cold and heat.


With a DIY home energy audit, you can follow a checklist to locate air leaks, identify energy-efficiency upgrades and find areas that need additional insulation. The best way to make your home more energy-efficient, however, is with a professional home energy audit, in which a professional efficiency expert visits your home and identifies ways to help you save money on energy costs.
