Site requirements for a Building Air Leakage Test
- The integrity of the structure must be complete prior to the test.
- Our air test engineer will need access to an external door (approximate size 2.1m high x 0.9m wide). An electrical supply within 25 metres of the doorway will also be required.
- All mechanical ventilation openings will be sealed with polythene sheet or self-adhesive tape during the test.
- All exterior doors and windows must be kept closed during the pressurisation tests. The actual test (after set up) is usually completed in well under one hour. During this period nopersonnel should enter or exit the building. It is preferable that the building is unoccupied.
Prior to attending site we shall require the following information:
- Floor plans and section drawings; and
- Design-stage SAP reports for each dwelling to be tested.
