Preparing your Reading site for the Air Tightness Test

One of our team will take measurements of the building from the architectural plans as well as undertaking physical site check of the measurements, prior to the air tightness test which allows us to determine the building envelope area. This is an essential stage of the air testing process as the building envelope area is one of the main parameters that the result is based upon.  The measurements will be verified onsite by APT Air Tightness Engineer on the day of the air test to ensure that the measurements and calculations are correct.

We then set up the blower door equipment as follows.

  1. We’ll temporarily install a blower door fan system (depending on building size) in a suitably placed doorway.
  2. We then take a series of environmental measurements such as internal and external temperatures as well as barometric pressures.
  3. We then turn on the fan equipment and take measurements between 25-70Pa in 5Pa increments, recording the pressure differential at each step.
  4. Finally, our technicians will calculate the total air flow required to achieve a pressure differential of 50 Pa, divided by the total building envelope area –  this calculation will show leakage rate in m³/h.m² @ 50 Pa.

APT Sound Testing usually allow 2-3 hours to complete each commercial air tightness test, meaning there should have plenty of time to address any unexpected problems that may arise. We will guide you through the entire air testing process. In addition, we provide an air tightness review consultancy service to help you pass your air tightness test at the first attempt.
