A Few Facts About Air Leakage Testing

Air leakage testing or air pressure testing has become mandatory for all the new buildings under Part L of the Building Regulations.

Air leakage means the uncontrolled flow of warm air out of the cracks and gaps of the building. These gaps are commonly present in the building’s envelope or fabric. This leakage leads to heat loss and energy wastage. To minimise the heat loss from the building, the air tightness of the building needs to be improved.

How is air leakage testing is carried out?

During the test, a fan or blower door test equipment is fixed on an external door of the building. The main function of this equipment is to move the air into and outside the building. The air leakage is measured by determining the rates of air flow which takes place through the fan. In addition to this, smoke generators are used to determine air leak points.

The whole process of air leakage testing is completed within 1 or 2 hours. During the test, it is recommended to seal any ventilation points present in the building.

After air leakage testing

Once the test is completed then the area from where air leaks are highlighted. As per the reports provided by the professionals who carried out the inspection, you need to fill or seal the cracks which are responsible for air leak. By doing this, you can increase the energy efficiency of the building greatly.
