What is commercial air pressure testing?

As part of the current Building Regulations (Approved Document L: Volume 2), commercial air pressure testing – also known as non-domestic air tightness testing – is a requirement for new build constructions and large extensions. Fortunately, in the UK we have CIBSE TM23, which is based on BS EN 13829:2001 ‘Thermal Performance of Buildings – Determination of Air Permeability of buildings – Fan pressurisation method’, to guide us through the procedure.

This ensures that all buildings are appropriately airtight; preventing uncontrolled flows of air (infiltrations or draughts) from entering through any gaps or cracks in the building fabric.

With superior air tightness come various benefits for your building, such as reduced heating costs, lowered carbon emissions, and a smaller requirement for Heating and Ventilation systems (HVAC). You can also enjoy greater comfort levels for occupants due to improved air quality. In fact, research has suggested that up to 40% of heat loss from buildings are caused by inadequate air tightness.

The process

The ‘blower door test’ is an industry-standard method for testing the air tightness of a home. A blower machine is mounted at the main entrance of the building (as pictured) to measure how much air leaks from inside. Thermal imaging tools are then used to pinpoint any loss of airflow.

Before and after the commercial air pressure test, we measure several environmental factors such as temperature, barometric pressure and wind speed to ensure that everything is in an optimal condition for your safety and convenience. In England and Wales, the Building Regulations in Volume 2 of the Approved Document L require that any commercial property undergoing an air pressure or an air tightness test should achieve a Permeability Result no higher than 8.00 m3/h/m2 at a 50 pascal pressure differential.

Our experienced team of professionals will take their time to make sure the job is done right. We can guarantee that any unexpected issues will be addressed without compromising quality. We are committed to providing you with trusted and knowledgeable service!

How to improve a buildings air tightness

Be sure to follow the Communities and Local Government’s recommended construction methods. Seal any gaps around pipes and cables when they penetrate walls, ceilings, or floors. Make sure that you apply mastic and caulking correctly during drylining; failing to seal joints with the ceiling or floor can result in air leaks.

Don’t forget to draught proof doors and windows – it’s a great way of preventing energy loss! Additionally, ensuring service hatches fit neatly into their frames is important, as well as adding draught stripping between the hatch and frame. Finally, repair damage to mortar joints and fill any holes in external walls for an airtight build.

What happens in the event of a fail?

It’s very likely that you’ll get a first-time pass. However, if this isn’t the case, we’ll assess where the issues are and outline potential solutions. If our assessment shows immediate improvements can be made we won’t charge you any extra to retest. If more time is needed to resolve the problem, one of our test engineers will come back at another day/time once all work has been done.

For complete peace of mind, why not ask us for a design review before building begins? Our experts are always on hand with advice and support throughout your project too.
