What Air Permeability Rating Do I Need?

Your air permeability rating resembles the amount of uncontrolled air that's leaking from the dwelling. A passing score in Saltburn-by-the-Sea is 10 m³/(h.m²). If the air test fails, we will help you identify where these leakage areas occur in the hope that a passing rate will be achieved following a re-test.

What Does An Air Leakage Test Involve?

Air tests cannot be carried out if the wind speed is more than 13mph - 3 metres per second is the ideal wind speed when undertaking an air test in Saltburn-by-the-Sea. 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.

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.

During an air test in Saltburn-by-the-Sea 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. 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.

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.

Do I Need An Air Leakage Test?

Part L of the Government building regulations explains that on a large plot of new houses that are built to a similar specification, only a sample of the houses will need to be air tested.

Planning your test in advance will help our experience air assessment team covering Saltburn-by-the-Sea to determine how many tests you'll need ahead of time per property and will be happy to offer advice on the best ways to gain your air permeability rating.

Domestic properties and commercial buildings over a certain size must have a passing air leakage certificate before the property can be handed over following a sale. All new buildings in England and Wales have had this requirement since 2006 and in Scotland this has been mandatory since 2010.

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%.
