Air Tightness Testing (also known as air leakage testing) is designed to measure the air permeability rating in a building. Excessive levels of air leakage can cause heat loss, which in turn has an adverse effect on a building’s energy efficiency and thermal performance. Meeting the specified targets for air tightness is a key requirement for building contractors to be fully Part L compliant.

As a registered member of the Air Tightness Testing and Measurement Association (ATTMA), Build Check is independently approved to carry out air tightness testing of all commercial and domestic building types.

Our UKAS-accredited engineers are highly trained technical experts with a thorough understanding of current building regulations, so we can intelligently interpret your results to offer you the highest standard of service.

Whether your requirement is for a domestic, commercial or industrial development, Build Check can support you with expert advice and consultancy on a full range of air tightness testing services including:

  • Design Review – Our experienced air tightness technician will conduct a complete air leakage review of design drawings to identify potential building envelope leakage paths and report constructive feedback.
  • Pre-Test Site Inspection – Build Check can offer pre-test inspection at various stages throughout construction to assess the construction of the building and identify any potential leakage paths, reporting all observations and recommendations.
  • Post-Test Fault Finding - If your building fails to achieve the target air permeability rate on testing, our air tightness technician can use a range of methods including: visual inspection; internal smoke testing and negative pressure to identify the main air leakage paths and recommend the most appropriate corrective measures required.
  • Training Seminars – These CPD air tightness seminars are designed to reduce air leakage rates by building awareness and understanding amongst design and construction staff.
