Paths can be interrupted by insulation and blocking air paths. A material's insulation is governed by mass, stiffening and damping...more
How loud is too loud?
Noise above 85 dBA over time will cause hearing loss. In general, the louder the noise, the less time required before hearing loss...more

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 Involve?
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 Kent, 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.
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 Kent.
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?
Your air permeability rating resembles the amount of uncontrolled air that's leaking from the dwelling. A passing score in Kent 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.
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.
All new buildings in England and Wales have had a mandatory requirement since 2006 (2010 in Scotland) that domestic and commercial buildings, over a certain size, must have a passing air leakage certificate before the property can be sold.
Planning your test in advance will help our experience air assessment team covering Kent 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.
