Air tightness testing is a requirement for many new domestic properties to be compliant with Approved Document Part L of the Building Regulations (Conservation of Fuel and Power). The Air Tightness Test checks the “air permeability” of the building fabric. Matt will seal all means of building ventilation (i.e. vents, fans etc.) before using a specialised fan door to either pressurise or depressurise the building. The building is then measured for air infiltration through gaps and cracks in the building fabric. A building with more air leakage will be more difficult to heat and keep heated.
Our Air Tightness Tester Matt has been a BINDT (British Institute of Non Destructive Testing) registered tester for 4 year and is able to provide quotations for tests and general advice on achieving good building air tightness.
Prior to contacting us please briefly read through the below checklist to better understand what can be expected.
When to Test
Buildings are tested at a completed stage, although ideally prior to final floor coverings being installed so remedial works to improve the air tightness can be carried out if required.
Before the Test:
On the Test Day:
Developments with similar buildings may only require a sample of the buildings to be tested instead of every one. Please contact us to discuss the sample that needs to be tested as this can vary depending on Building Control requirements.
