The Air Tightness Testing and Measurement Association (ATTMA) is a special interest group within The British Institute of Non-Destructive Testing (BINDT) dealing with air permeability of all building types.
It comprises organisations that are experienced UKAS-accredited air testing bodies who have undergone further technical appraisal by ATTMA.
ATTMA members are BINDT Registered for testing dwellings (ADL1) and non-dwellings (ADL2).
The requirement for air tightness of buildings in the UK is driven by the Building Regulations. In England & Wales, the majority of new building projects will require air testing.
Improving air tightness is an important factor in reducing carbon emissions in buildings. By reducing air permeability, less heated/cooled air escapes and less unheated/uncooled air infiltrates which lowers space heating and cooling loads and greatly improves occupant comfort levels.
