Building Air Leakage Testing

The test measures air leakage rates through a building envelope under controlled pressurization and depressurization.

Building air leakage testing.

As leaders in building air tightness testing and facade leakage we offer advice solutions and on demand testing to deliver the results for your project with our attma registered air tightness testers located in melbourne sydney brisbane and perth. In essence it is a measure of heat loss through cold draughts. At a test pressure of 75 pa 0 3 in a leakage rate of 0 4 cfm sq ft of air barrier would be a very high leakage rate and 0 1 cfm sq ft would be a very low leakage rate. We use a computer to control 3 fan systems that speed up and down to measure the amount of air leakage and various pressure levels.

By specification these leakage rates are measured while the building is at a pressure difference of 50 to 75 pa between the interior and exterior. During this process we record the air leakage rates and present them in a graph form in the final report. Air tightness testing is a process in which the building envelope is tested to quantify the air tightness. Air testing also known as air pressure testing or air tightness testing is a requirement of the building regulations.

During an air barrier test our experts use large commercial fans to depressurize and pressurize the building.
