The Decibel Scale
Gives an approx of human perception of loudness. This is because the human ear has a logarithmic response to changes in sound level...more
Decibels (dB) are most commonly used as a measure of sound level, but they are also used in electronics, signals and communications...more

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 Droylsden. 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.
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.
Employees can still do their job inside a commercial building in Droylsden, within reason, though may feel some discomfort due to the noise of the fan and the draught that will be felt throughout the building. There should be no outside access once the test has begun - which lasts for approximately 90 minutes, so plan accordingly.
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.
What Air Permeability Rating Do I Need?
A passing score in Droylsden 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.
Do I Need An Air Leakage Test?
Planning your test in advance will help our experience air assessment team covering Droylsden 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.
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. This is outlined in Part L of Government building regulations.
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?
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%
