Backdrafting In Our Homes

What is backdrafting? Backdrafting is the reverse and unwanted flow of exhaust gases from fuel-fired appliances back into a home. Fuel-fired appliances use the oxygen present in air for the combustion process, and also use air to dilute toxic gases in the exhaust vent pipe or chimney. Combustion and dilution air can be supplied directly to the appliance (direct-vent) or can be pulled from…

Indoor Air Quality: What are we breathing in?

According to the Ontario Ministry of Environment, an average adult breathes in around 15,000 litres of air every day. Statistically, people spend 90% of their time indoors.  The majority of that time is spent at home, therefore it is extremely important that our homes provide a healthy living environment. Indoor Air Quality (IAQ) refers to the air quality within buildings…
