Accurate Airtight Exteriors, Consulting & Testing

PROFESSIONALS

The largest energy loss in most buildings is air leakage, the air moving in and out of a building. There are four barriers (insulation, water, vapor, and air) to a heated or cooled building that make it comfortable and energy efficient. Air leakage is defined as the uncontrolled migration of conditioned air through the building envelope caused by pressure differences due to wind, stack effect, and mechanical systems. It has been shown to represent one of the single largest sources of heat loss and gain through the building enclosure of most buildings. Tests carried out by the National Research Council of Canada on high-rise commercial and residential buildings, schools, supermarkets, and houses have shown levels of 30% to 50% of heat loss could be attributed to air leakage. To determine the amount of total air leakage in a building, a blower door test must be conducted. Next, diagnostic testing is conducted to determine where penetrations are in the air barrier and where to seal these leaks. Then a final diagnostic blower door test is done to determine the amount of air infiltration reduced. This number can then be converted to determine the total energy savings per year, and can be used for state rewards and federal tax credits. 

We are certified to test air infiltration for commercial buildings often called air barrier testing.

Just wanted to give you some feedback on the crew you've got out here. The crew arrived right on time and got to work. He has been great about explaining things as he went and answered my questions in terms I understand.
