Attic access door


The attic access door can also be a source of excessive heat loss. Installing proper weatherstripping and a locking mechanism will help reduce heat loss.

Ceilings and attics


The attic is a vital part of your home that requires proper ventilation. The recommended R-value in Northwestern New Brunswick is R-40.

Recessed lighting fixtures


Spaces around recessed lighting fixtures in ceilings that can be a source of air loss must be sealed. Stained insulation or frost in the winter are sure signs of hot air leaks in the attic.

Electrical outlets


Air can escape through electrical wall outlets, which must be properly sealed by installing CSA-approved foam cushions. Place safety seals in outlets that are seldom used.

Clothes dryer air outlet


Replace the clothes dryer air outlet with an energy efficient outlet system, and seal the outlet hose with polyurethane and the frame with acrylic latex.



An uninsulated end joist will make the basement and ground floor much colder. Joists must be insulated to an R-20 rating.



Basements represent 20 to 35% of all heat loss in a home, due to their large, uninsulated surface above and below ground level. Contrary to popular belief, earth has very poor insulation properties. Thus, the foundation must be insulated against heat loss.

Exterior walls


Exterior walls account for 10 to 30% of heat loss. Exterior walls must normally be insulated to a minimum R-20 value. It is also important to consider air and vapour barriers.
