Air tightness and permeability testing

Air tightness testing

Air Permeability Testing in accordance with Part L of the Building Regulations.

Our technicians can carry out air permeability testing on any size of structure, zone within that structure or ducted system. All testing is carried out in accordance with current BS EN 13829 standards.

What is air permeability tightness pressure testing?

Air permeability tightness pressure testing is a method of measuring and quantifying the air leakage of a building. Too much air leakage leads to heat loss resulting in higher C02 emissions. Reducing C02 emissions is the purpose of ‘Part L’ of the new building regulations through air tightness testing, air leakage testing and air permeability testing.

Why test for air tightness pressure?

For all new domestic housing a proportion must be Air pressure tested  as required in accordance with the guidance given in Part L1A – Conservation of fuel and power in new dwellings of the Building Regulations. Testing the air tightness of existing dwellings can highlight areas of problems that can be treated cost effectively to improve the energy efficiency of the dwelling as a whole.

Air Tightness Testing (AKA Air Permeability Testing Air Leakage Testing, Air Pressure testing) is the test to measure the rate at which air leaks through the external building fabric.

It’s not only important to consider the air tightness to determine how energy efficient a building is, but it is also a mandatory component of Building Regulations in the UK since 2006.Trace Surveys performs accredited Air Tightness Testing, and all our tests comply with the current standards.

Trace is able to provide Air Tightness testing for both Level 1 and Level 2 properties.

Level 1: For dwellings (or other non-residential premises) less than or equal to 4000 m2 gross envelope area.

Level 2: For (usually) commercial buildings greater than 4000 m2 gross envelope area.

Our experienced technicians can be mobilised at short notice, and we’ll work with client program. Trace will offer you the best chance of success, and hence will provide you advice on-site if an Air Tightness failed to meet requirements. If remedial works can be carried out on-site (expanding foam, silicon or caulk), then we will aim to re-test immediately to facilitate a successful outcome.

Trace Surveys offers cost-effective packages for Air Tightness Testing especially when the testing is part of our full consultancy and testing package.
