Air Testing is sometimes referred to as Domestic Air tests, Domestic Air pressure testing, Domestic Air tightness testing, Domestic Air pressure tests, Domestic Air leakage testing, Domestic Air tightness tests.

How Many Properties Need An Air Tightness Test?

The number of tests required are as follows:

• 4 or less properties of the same type: one test needed per type
• More than 4 but less than 40 dwellings of a type: at least two tests of each type
• More than 40 properties of a type: 5% of each type UNLESS the first 5 get a passing score - then this can be dropped to just 2%

What Does An Air Leakage Test in Rotherhithe Involve?

There should be no outside access once the test has begun for approximately 90 minutes so plan accordingly. Workers can still do their job inside the property, within reason, though may feel some discomfort due to the noise of the fan and the draught that will be felt throughout the building.

Whilst the air tightness test is being undertaken, furniture will not be affected but smaller items such as paper must be held down or removed completely so they're not blown about. The pressure of the room will be tested and as such all windows and doors that lead outside must be securely closed to avoid them swinging open and the test being abandoned. Similarly, all internal doors should be wedged open to avoid being slammed shut.

An air test involves placing a large fan, or several fans, to an opening within the property; usually a doorway. The fans will increase and decrease in speed that will in-turn change the building's air pressure and record the results. Please note: an air test cannot be carried out if wind speed is more than 13mph. 3 metres per second is the ideal wind speed when undertaking an air test in Rotherhithe.

What Air Permeability Rating Do I Need?

A passing score in Rotherhithe is 10 m³/(h.m²) for an air permeability rating which resembles the amount of uncontrolled air that's leaking from the dwelling. Should the test fail, our air tightness team will help you identify where the leakages are happening in the hope that a passing score will be achieved after a re-test.

When Should The Test Take Place?

For obvious reasons, an air pressure test is generally one of the last surveys to be undertaken once all the walls, windows, doors etc. are complete and sealed to stop any air escaping and prevent drafts through the property. The building envelope will also need to be completed.
