The R value of insulation is the measure of how the material reflects heat back outside. The higher the R value, the better the insulation. Inadequate insulation is from four to seven inches which has an R value of between 15 and 21. Good insulation is between 13 and 18 inches for an R value of between 38 and 49. In the Chicagoland area, this is your best bet.
Why Insulate The Attic?
Things happen on a roof that’s detrimental to a house. An improperly insulated roof creates ice dams when heat in the attic melts snow. It also keeps heat in thus lowering your power bill.
Types Of Insulation
The type of insulation you use depends on the space in the attic. Batting is installed between the joists and offers an R value of three to 3.5 per inch. Roof insulation in Wilmette usually uses rolls on the floor.
Loose fill is blown into empty spaces in unfinished attics. It offers an R value of between two and four per inch. Batt and roll and loose fill are generally fiberglass insulation.
Spray foam insulation is similar to loose fill, but it solidifies for an R value of between 3.5 and 6.5 per inch. Showalter Roofing Services will be happy to help you with your insulation when you contact us online to learn more.
