The Attic

This is one of the easiest places to insulate in your home. It’s also the place where insulation has its greatest impact in keeping the heat in during winter and keeping the heat out in summer.

New construction

1. Install batts from below, pressing into position between joists. For additional insulation lay batts across the top of the joists.
  • Butt ends tightly together to eliminate gaps
  • 2. Install an approved vapor barrier/retarder on the interior surface where required. 
    • Overlap joints over two adjacent ceiling joints
    • Seal with approved caulk or tape
Existing construction
When no insulation is present:
  • Install COMFORTBATT® between joists.
    1. For additional insulation, lay a second layer of insulation perpendicular to the first layer.

    For existing, but insufficient insulation:

    • Level existing insulation to top of joist.
    • Lay COMFORTBATT® on top of joists in opposite direction.
    • Ensure batts are butted against each other tightly.
    • Fit batts closely to cross members; cut batt if necessary;leave no space between layers.
    • Insulate attic hatch to same level as rest of attic. Apply weatherstripping to edge to reduce air leakage.
    • Only insulate close to IC rated electrical fixtures. Maintain 3-inch distance from others.
    • Follow manufacturer instructions and local building code to insulate around chimney.
