Considerations for Reducing Air Leakage in Your Home
In older homes, air leakage can account for more than one-third of your energy bill. Air leaks don’t just waste energy, they can also make your home uncomfortable and cause a number of indoor air-quality problems.
Air leaks into homes through cracks and joints, particularly where your home sits on the foundation and around windows and doors. This can cause drafts, dry air and cold feet. Warm air leaking out of your home through upper storey windows and the attic can lead to moisture damage and wood rot. Because air leakage can account for such a large portion of your home’s heat loss, it should be the first area targeted for energy efficiency.
Sealing air leaks is often quite inexpensive and if you are a “do-it-yourselfer” this is a job you can consider doing.

Window technology has advanced rapidly in recent years. Today’s most energy-efficient windows can actually gain more heat from the sun than they loose at night, helping to heat your home. As well, advanced window design virtually eliminates air leaks and drafts.
If your renovation plans involve replacing existing windows or adding new ones, selecting high performance windows can cut your heating costs and increase the comfort of your home.Consumer’s Guide to Buying Energy-Efficient Windows and Doors, available online from Natural Resources Canada’s Office of Energy Efficiency, explains window and door technology and how ratings work, and helps you make informed purchasing decsions.
