Air Tightness Testing

What is Air Tightness Testing!!!

Air tightness testing measures the flow of air within a building. Air leakage is the uncontrolled flow of air through gaps and cracks in the fabric of a building. Improving air tightness in a dwelling can reduce air leakage.

The aim of air tightness is to "build tight, ventilate right". This means that there are no breaks or gaps in the envelope of the building fabric and there is complete control over the ventilation system within the building. Having an airtight property does not mean there is insufficient air flow, it means there is controlled air flow.

The only satisfactory way to measure air tightness is by using blower door test equipment. By the use of building pressurisation / depressurisation testing using the blower door it is possible to quantify the air leakage rate from a building and to also assess exactly where this leakage may be taking place.

These areas are increasing your energy consumption and, with it, the amount of money your property is wasting. Air tightness testing combined with thermal imaging can identify specific air-leakage pathways or other problems and therefore allow you to make the necessary changes to increase the energy efficiency of your property.

Research shows that up to half of all heat loss in buildings can be due to air leakage and uncontrolled ventilation.

Benefits of Air Pressure Tests in new and existing buildings

  • Air pressure tests can be used to increase the energy efficiency of existing dwelling.
  • Air leakage testing helps identify areas of a building experiencing heat loss.
  • Air leakage testing helps minimise energy usage in a dwelling hence reducing costs.
  • Air leakage testing plays a vital role in achieving an "A" rated cert for a dwelling.
  • Air pressure tests in conjunction with Thermal Imaging can locate the inefficiencies in your building
