How to Reduce Air Leakage in Your Home
In older homes, air leakage can account for more and one-third of your energy bill. And air leaks don't just waste energy, they can 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.
Natural Resources Canada's Office of Energy Efficiency publishes Air Leakage Control, an excellent fact sheet that explains how to detect and seal air leaks in your home.
