R-value refers to the ability of insulation to resist conducting heat. The R-value required by building codes varies by location, so determine what r-value is required by using the map available on the North American Insulation Manufacturers' website. A higher R-value insulates more effectively, reducing heating and cooling costs.

Batt and roll insulation require only simple tools and technique to install. Batts are pre-sized and require fewer steps if the wall spacing and height are standard. Rolls are a standard width but must be cut to length. Blown-in insulation can save time, but requires specialized equipment. Ensure enough insulation is on hand prior to starting by using an insulation calculator like the one found on the Lowe's website.

"Friction-fitting" involves placing batts or cut pieces of rolls into the wall cavity before adjusting them to fit. This allows you to limit trips up and down the ladder. Working around obstructions such as gas, plumbing, and electrical lines may require splitting the insulation to fit. A sharp knife is essential.
