Building Air Leakage Testing

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.

Building air leakage testing. 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. 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.

The test measures air leakage rates through a building envelope under controlled pressurization and depressurization. With few exceptions new dwellings will require an air leakage test as part of the building control post construction sign off procedure. 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.

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.
