Best Practices For Attic Insulation
Proper attic insulation minimises heat loss in winter and keeps homes cooler in summer, reducing air conditioning bills. But poor attic insulation or gaps between the ceiling joists can reduce a house’s energy efficiency and make heating systems work harder, shortening their lifespans. The top mistake people make when insulating their attics is not ensuring they have enough insulation. Ideally, attic floor insulation should be up to the height of the ceiling joists.

The attic spray foam insulation hatch or pull-down stairs should be insulated, as well as any attic vents. These allow warm attic air to leak into the living space, wasting energy. Also, any electrical junction boxes should be sealed, or if the boxes aren’t already insulated, they should be covered with insulation.

Add Insulation, Increase Comfort: Make Your Home Cozier Year-Round

When installing blown-in attic insulation, a special attention should be paid to difficult-to-reach areas, such as corners of hip roofs, spaces under mechanical platforms and around ductwork. This can be done by adding insulation batts before the drywall is installed (see photo).

When securing attic floor insulation to the wooden joists, staples or adhesive spray should not be used as they may compress it, lowering its R-value. Alternatively, stapleless fasteners can be used, or insulation supports can be attached to the joists in a criss-cross pattern to prevent the material from blowing. Depending on the climate, cellulose, fiberglass or foam insulation can be used in attics. The choice of insulation material should be based on the attic’s R-value requirement, which differs by climate.
