Air Tightness Testing

What is an air tightness test?

An air tightness test or blower door test is used to calculate the uncontrolled air permeability of a dwelling through the building fabric. This is done by placing a large fan at the front door of the house & creating a pressure difference of at least 50 pascals to calculate the rate of permeability. A house with a lower rate of air permeability will be cheaper to run, and if the rate of air permeability is too high, the house will cost more to run. If its a new build it could fail the air pressure test and then the house will not comply with building regulations. If a house fails, the air tightness tester will be able to identify the problem on site so it can be rectified.

Who requires an air tightness test?

An air tightness test is required for all new dwellings under technical guidance document part L 2019. Dwellings which fall under these regulations are ones that have applied for planning permission after 1st of November 2019 and they must achieve an air tightness target of lower than 5 ach/hr. Houses which received their planning permission before 1st of November 2019 fall under the TGD part L 2011 regulations, this is provided they have the building complete before 1st of November 2020, and only has to achieve a target of lower than 7 ach/hr.

It can be beneficial to have an air tightness test carried out on an existing building, particularly when retrofitting tor the following reasons:

  • To ensure that any measures to seal the house for air tightness have been effective.
  • To ensure there is not an excessive loss of heat due to very poor air tightness when retrofitting a heat pump.
  • To improve the BER rating of the property.
  • To identify any problem areas that may result in unwanted heat loss or draughts when upgrade works on a house has been completed.
