Completed Sidewall Insulation

It's not unusual to discover that while your attic is insulated, your sidewalls are not. Unfortunately, you can still lose a lot of heat and cold through your walls, especially around vents, electrical features, and other units.

Let Illinois Valley Insulation finish off your insulation with a sidewall application. We'll let you know whether spray foam or blown materials are the way to go and ensure you get proper service that does the job!
