Air tightness testing

In order to demonstrate compliance with Part L Building regulations buildings should be designed with adequate ventilation provision. Above this designed or “controlled” ventilation, a further amount of uncontrolled air “infiltration” is tolerated, and this will vary according to the overall design of the building. On completion of the building, an air tightness test measures the “uncontrolled” ventilation the general minimum level for design air permeability is 10m3 per hour per m2 of the building envelope at a maintained pressure differential of 50 PASCAL’s.

Air Tightness Testing Explained

Pre-inspection advice
In order to guarantee a pass first time we offer a checklist which if followed all but guarantees a pass first time. If you have any worries about a particular detail we can arrange a site visit to incorporate tool box training for those managing the work and the relevant subcontractors whose work is vital to the success of the test.

Fully accredited testing
We liaise closely with site management to ensure that testing in conducted with the minimum of disruption. In addition to the actual testing, our service includes the detailed calculation of the dwelling’s ‘air barrier envelope area’, all necessary test preparation, such as temporary sealing of ventilation, and in the event of test-failure, we conduct a thorough inspection of the dwelling, using smoke testing techniques to locate the air leakage sites.

On-site consultation
The provision of an air-tightness expert to inspect air-barrier details within ‘work in progress’ plots on site can be of considerable assistance to hard-pressed Site Managers. Not only can potential problem areas be identified and addressed early in the programme, our detailed, illustrated reports provide invaluable third-party evidence to put before potentially culpable sub-contractors.
