Airtightness is essentially the degree to which a building lacks air leakage.Air leakage is responsible for up to 40% of your heating load and the whole house comfort. In order to find out how tight your house is, we use an instrumented and calibrated fan mounted in an exterior door to measure the air change rate.The air change rate is a measure of how often the air in your house changes each hour. We do our measurement at a pressure equivalent to a 50 mph wind.To locate with smoke test or infrared camera the air leakage.
