Air Tightness Testing

Air tightness testing can be a very tricky business for anyone during a construction project.

Air leakages found in new buildings contributes to increased fuel consumption and higher energy bills.

This is why the Building Regulations/ Standards requires all new buildings to have an air tightness rating, without which a Building Control officer or Verifier will not provide that all-important completion certificate.

What is Air Tightness Testing?

Air tightness testing, also referred to as air pressure testing, is used to determine the amount of uncontrolled air leakage through gaps and cracks within the building. These gaps and cracks are not easily detected through a visual inspection; therefore, a pressure test is carried out to measure the air leakage of the entire building.

Do I need an Air Tightness Test?

An air tightness test is required by Building Regulations/Standards after construction of a new building (commercial or residential). The results of this air pressure test are used within energy efficiency calculations (SAP or SBEM).

There are of course some exemptions that apply for air tightness in dwellings and in commercial buildings, which are detailed within the technical booklets/approved documents.

Western Isles Energy and Property Services are accredited and audited through BINDT to carry out Air Tightness Testing to approved standards

We can also provide this service within a package of SAP or SBEM calculations which are also mandatory requirements for new buildings.
