                  Air Testing-   

Air testing is a recognised method of measuring the extent to which air is lost through leaks in the building fabric. 

It can be referred to as air testing or air pressure testing. Failing to maintain air tightness can result in up to 40% heat loss. 

If you’re investing in energy efficiency measures, such as a new boiler or extra insulation, your efforts could be irrelevant if the building’s air testing isn’t adequate.

The air test target is established by the design stage SAP calculation. This will determine if 100% or sample testing is required for the development. Please speak to your SAP assessor about your Air testing obligation.

Here at ATSPACE our experienced Air Testing Engineers carry out a large number of tests on a weekly basis, and therefore, if a failure occurs, we have the experience and knowledge to identify Air leakage paths within the construction. If the property fails the Air test, our Engineer will stay on site for a reasonable time period to rectify any minor issues.

We can save you money by combining your air test with a ventilation test - just ask for more information.

We will also provide you with a free easy to read checklist to help prepare your build for the air test in advance of us turning up. It is included within the service and is sent in advance of the test date to assist you, as the small things can make a big difference when it comes to passing the air testing processes first time.
