Why you need air tightness testing

Air leakage is the uncontrolled air loss (air infiltration) from a building through cracks and holes. If the air loss is too high then a building will be draughty, uncomfortable to live in and will have high heating bills. The building is pressure tested to ensure that it has been constructed to a good standard and that it can achieve the pass score which has been calculated in the SAP calculation. The test is a means of quantifying how much air leaks into or out of the building.

Achieving a good standard of air tightness results in lower energy bills and a building which is comfortable for the occupants.
