How long does an air test take?
There are many things to consider when performing a test; the size of the building to be tested, its complexity and also the air leakage to be achieved. Most tests can be completed in 1-2 hours, although some may take much longer if low air leakage rates like AECB Silver Standard or Passivhaus are required.
When will I get the results?
Usually, results are given at the end of the test and a full report and compliance certificate is issued within 24 hours.
What is an air leakage test?
Air leakage testing is the method of calculating air leakage caused by uncontrolled ventilation such as pipe and skirting boards, etc. The air test is part of the information required for Part L calculation (SAP or SBEM) and is ultimately required for EPC production.
Do I need an air test and what’s it for?
If it’s a new building, then the likelihood is, yes, as set out in Part L (ADL) of Building Regulations Approved Document. As well as satisfying ADL, it also helps to reduce carbon emissions due to heat flow through unwanted building fabric gaps. For example, we can use it to detect and use building fabric deficiencies in conjunction with smoke testing and infrared thermography.
What happens if a building fails a test?
We work with the client to help a building pass a test. If too much work is needed, the test will require another visit.
How much is an air test?
Air tightness testing prices start at just £50 per plot. Size, complexity, location and quantities all affect the quotation, so please get in touch for more information.
