How Many Properties Need An Air Tightness Test?

According to Part L1a, an air pressure test needs to be undertaken on 50% of all dwelling types or three units of each type depending on which value is smaller. A block of flats is considered as a separate development and should be treated as such no matter on the number of blocks on the site. Furthermore, the testing should be done on the first batch of each type of dwelling to be completed. The need to test multiple versions of each type is to confirm the design and construction procedures are up to code according to Government regulations.

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?

The air tightness rating of a property is not a fixed figure. This is set by the design SAP Calculation carried out (please contact us if you also require a SAP Calculation in Oldbury ). However the worst acceptable standard for air tightness is 10 m³/(h.m²) which resembles the amount of uncontrolled air that's leaking from the dwelling. However this does not mean that it would pass the SAP Calculations Design Air Permeability standard. 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.

What Does An Air Leakage Test in Oldbury Involve?

During an air test in Oldbury 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.

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 Oldbury.
