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

When Should The Test Take Place?

The air leakage should be completed once the building is completed. All doors and windows in place, all skirting boards sealed, traps filled with water and any penetrations through the envelope of the building need to be sealed. Please find checklist within the downloads section of the website which provide a comprehensive list of requirements. People who follow this checklist have a much higher change of passing the air test first time.

What Does An Air Leakage Test in Berwick upon Tweed Involve?

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 Berwick upon Tweed 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.

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 Berwick upon Tweed.

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 Berwick upon Tweed 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. The final target will be set by the design SAP Calculation (please contact us if you require one of these in Berwick upon Tweed )

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%.
