• Air Leakage Testing

    Air Tightness Testing 750

    As part of our suite of construction site services, Hilson Moran can also offer air leakage testing of residential and commercial properties through our approved partner, Energist.

    Part L of the Building Regulations requires a sample of all newly built homes to be air tested to ensure compliance with the regulations. This is particularly important as air leakage testing is a critical contributor to an Energy Performance Certificate. Air leakage test results should be less than the figure specified in the design SAP or SBEM assessment.

    The testing is undertaken by Energist engineers who are fully BINDT accredited, and CSCS and health and safety compliant. Once on site, the engineer will complete a check of the building/dwelling to ensure it is ready for testing, ensuring all doors, windows and any other relevant apertures are sealed.

    Testing is undertaken to determine leakage in m3 per m2 of external envelope lost to uncontrolled air leakage per hour.
