Building Air Leakage Testing

With few exceptions new dwellings will require an air leakage test as part of the building control post construction sign off procedure.

Building air leakage testing.

During an air barrier test our experts use large commercial fans to depressurize and pressurize the building. 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. The test measures air leakage rates through a building envelope under controlled pressurization and depressurization. Air tightness testing is a process in which the building envelope is tested to quantify the air tightness.

An air leakage test is a test to determine the level of uncontrolled air flow through gaps or cracks in the fabric of a building. Part l states that new developments must meet specific air permeability targets to minimise the risk of heat loss and energy inefficiency caused by air leakage. 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. 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.

During this process we record the air leakage rates and present them in a graph form in the final report.
