Insulation

Not every attic needs spray foam at the roofline. Green Attic reviews how the attic is meant to dry before recommending spray foam or another insulation plan.

Spray foam insulation in Chicagoland starts at about $0.75 per sq ft for 1 inch of open-cell spray foam and $1.25 per sq ft for 1 inch of closed-cell spray foam. Final pricing varies based on foam type, thickness, access, prep work, old insulation and more.

Yes, insulating interior walls can improve energy efficiency, reduce noise, and enhance comfort, but it's essential to weigh the benefits against the costs and potential drawbacks.
