Commercial Air Pressure Testing

Gladwood have carried out hundreds of commercial tests over the last 10+ years.

We are able to test Commercial buildings up to 4000menvelope area (based on a design air permeability rate of 10 (m³/h.m² @ 50Pa)). 


Our services include the following…

Air testing service:

Our basic service includes envelope area calculation, site set up and air test. We allow up to four hours on site with our basic package, so if the building fails it’s first test and the problem can be rectified during this four hour period, then the re-test is free of charge. 

Drawing reviews:

Review of the design drawings and details, identifying any problems and producing a report confirming the key concerns and suggested improvements.

Site inspections:

Usually, two site visits are required, the first inspection during the ‘first fix’ of services and the second at ‘second fix’ stage. The report issued for each inspection will include recommendations, site photographs and sketches of problem areas to help convey the issues to the ‘trades’ on site.

Sample air testing:

Agreed testing at key points during the build, this is particularly useful when targeting a very low design rate.


We carry out testing in accordance with ATTMA guidance and in conjunction with Building Control for Part L approval.
