| Drafts around windows, through doors, everywhere? Drafts are the major cause of comfort problems for homeowners. Not only do they make it uncomfortable to sit beside a particular window, or to work at your desk in that spare bedroom, they also make your heating bills go up as your furnace struggles to deliver extra heat. Canada Mortgage & Housing Corporation and the National Research Council of Canada have stated that air leakage and drafts can cause up to 40% of the heat loss from a building. That means that 40% of the money you spend to make the air in your house warm (or cool in summer) disappears through holes! In a recent survey done by the Government of Canada for the Energuide program, 90% of the homes surveyed listed air barrier leakage as the major loss of heating energy. And, it's not only warm air that goes out and cold air that comes in through these leaks. They're also excellent pathways for bad smells, dirt and dust, pollen, flies, even ants and cockroaches. Zerodraft Calgary uses Blower Door technology to measure the rate of air leakage in your home. We will find out just how much leakage there is and give you an estimate to resolve it.
