In the Chicagoland area you need to have between R-49 and R-60 for your attic. Realistically, you should be at R-49 or higher. We recommend R60 because insulation will settle over time. If you live in an older home, you should have more insulation because it is likely not air sealed the same way a newer home is.

Choosing the right insulation for your attic can significantly affect your home's energy efficiency, and cellulose insulation stands out as a top choice.

Cellulose insulation, made mainly from recycled paper, provides excellent thermal performance, reducing energy costs. It has a high R-value, meaning it's effective at keeping your home warm in the winter and cool in the summer.

Beyond thermal efficiency, cellulose is environmentally friendly, being both made from recycled material and biodegradable. It also provides sound insulation and has high density that allows it to fill gaps more thoroughly than other insulation types.

Despite being paper-based, cellulose is safe as it's treated with fire retardants. Considering its thermal resistance, eco-friendliness, and cost-effectiveness, cellulose insulation is a superior choice for attic insulation.

Attic insulation cost is between $1.90 and $2.50 per sq. ft for R49- R60 Cellulose or Fiberglass. Closed cell spray foam insulation price will range from $3.50 per sq. ft. for R21 to $7 per sq. ft. for R49. Price will vary depending on the type of insulation we use, sq. ft. of the house and roof or wall structure.
