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

How Many Properties Need An Air Tightness Test?

If you have 4 or less properties of the same type then only one test needs to be undertaken per type. If you have more than 4 but less than 40 dwellings of a type then you need at least two tests to be done on each type. Finally, if there are more than 40 properties of a particular type then at least 5% of each type needs to be tested UNLESS the first 5 get a passing score - then this can be dropped to just 2%.

What Does An Air Leakage Test in Denbigh Involve?

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 Denbigh.

During an air test in Denbigh the pressure of the building 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. Furniture will not be affected during the test, but smaller items such as paper must be held down or removed completely so they're not blown about.

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.

Why E2 Consultants?

All new buildings in England and Wales have had a mandatory requirement since 2006 (2010 in Scotland) that domestic and commercial buildings, must have a passing air leakage certificate before the property can be passed off by building regulations.

E2 Consultants offer a range of services from desktop reviews of drawings to pre test inspections on site to advice on air tightness, how to improve and what needs to be completed and sealed for the testing to take place successfully.

When Should The Test Take Place?

A building envelope will need to be completed before the air test takes place - which should be one of the last surveys undertaken once all the walls, windows, doors etc. are complete and sealed. This ensures no air will escape and prevent drafts through the property which will in-turn improve your air permeability score.

What Air Permeability Rating Do I Need?

A passing score in Denbigh 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.
