This webpage is to be read with our ATTMA Australia Guide to Air Tightness Targets. The guide which is downloadable here – is designed to act as a guide to air tightness targets. These suggest targets may serve as design guidance for current Australian construction and as tarting point for discussion. Individual projects may choose a more lenient or more stringent target based on their sustainability goals, budget and experience.
We aim to add more examples of projects and this area will be updated when ATTMA receive these projects.
This list is always evolving, based on test results submitted to ATTMA Lodgement and feedback from ATTMA testers. The table shows the recommended design air permeability. Search for your building type, or scroll through the pages. Below the table you will be able to find out more details about projects that ATTMA have examples for.
Building enclosure airtightness for any building type should always be paired with effective and appropriate ventilation
