- 2). Push more insulation into the cavity, and install a second wire hanger--space the wire hangers eight inches apart. Continue in this fashion until the entire cavity has been filled with insulation. At the end of the cavity, cut the roll of insulation (if necessary) with scissors. Continue on to the other areas between the floor joists, until the entire floor has been insulated.
