What is air tightness testing?

Air tightness is a very important consideration in all climate regions and a majority of countries globally, now mandate minimum performance levels. Find out why it should be a priority for your building.

Source: Australian Building Codes Board, General information only.

All buildings unintentionally leak air, in and out. Air tightness testing identifies the amount of leakage that occurs and offers the opportunity to minimise it. The higher the air tightness level, the less unwanted  infiltration will occur.

Poor design, substandard construction, unsuitable building methods and materials can lead to high volumes of unwanted air infiltration breaching the building’s fabric. These unwanted air pathways should be kept to a minimum. 

What does air infiltration affect?

  • the durability of the building;
  • the occupant comfort;
  • the indoor air quality;
  • the occurrence of mould and;
  • the amount of energy consumed to heat or cool the building.

let's talk about your project

Some very simple guidelines:

  • It’s never too early to consider air tightness and its impacts on a project.
  • Irrespective of the building type, use or form, all buildings have the same challenges when trying to provide a stable environment internally.
  • Engage a professional early to get the most economical and effective result.
  • Test twice, once during construction and once at the end of construction.
  • Ensure your tester is qualified , accredited and testing to an international standard.

what our clients say



John assisted us with the permeability testing for a Green Star project with a leading developer in the industrial sector. ATTSA was very professional and gave plenty of advice to assist in improving the results, both before and during the testing process. I would highly recommend John and ATTSA for permeability testing.

Alistair Coulstock - Action Sustainability Asia Pacific Pty Ltd


Hutchinson recognise the relationship between good buildings and tight buildings. We have engaged ATTSA to carry out blower door testing on a number of our recent projects and found their experience and application invaluable. We will use ATTSA again wherever we require blower door testing.
