Frequently Asked Questions

Air Pressure Testing

Air pressure tests calculate air tightness in a building, known as “air permeability” or “leakage”. Air leaks are the air that escapes from the building by uncontrolled means. Leaks can occur through voids, holes or cracks in the building fabric.

Domestic Air Pressure Testing .We have EAS certification to perform every test according to CIBSE TM23.

VALUE Air pressure tests from £175.00 + VAT with substantial discounts when multiple dwellings can be tested at once.

A good air permeability test result will improve your Dwelling Emission Rate (DER) or Building Emission Rate (BER) and reduce the heating bill of the house or building.

We allow up to two hours for each air pressure test for dwellings and up to four hours for commercial buildings. This allows the client enough time to complete a reasonable amount of remedial works should they be required. If the property passes a certificate will be issued which should be passed to the Building Control Body (Building Regulations) within seven days of the air testing test being carried out. Contact usWe will be able to assist you through the entire air testing process, from preliminary design to the final testing stage.

If you have constructed a new dwelling, then Part L of the Regulations states that you must now have an air tightness test performed on that dwelling to assess air leakage. The air permeability of the building must meet the latest Building Regulations standard for conservation of fuel and power (currently  8m3/h/m2 @ 50 Pascals).

Air tightness construction is a draught-free envelope – quite simply this means that there are no unintended gaps in the envelope that allow air to leak in or out of the property. This means there are no cold draughts coming in through the property.

A standard house has an air tightness of between 3 to 10 m3/h/m2 @ 50pa. The majority of dwellings that we test have a design air permeability of around 5 m3/h/m2 @ 50pa. Commercial buildings can vary substantially dependant of the building type, generally ranging from targets of 3 m3/h/m2 @ 50pa to 8 m3/h/m2 @ 50pa.

Tips to Help Pass an Air Pressure Test first time by reducing air leakage:

1. Every service penetration is sealed.

2. All plumbing work is complete with water in the traps.

3. Build to Accredited Construction Details or similar.

4. Gaps within walls and floors must be sealed.

5. Bathrooms and kitchens must be fully fitted and mastic sealed.

6. No work trades to be in the building where the testing is carried out.

Air testing is a recognised method of measuring the extent to which air is lost through leaks in the building fabric (air leakage). It is sometimes referred to as air tightness testing.

SAP Calculations (domestic) or SBEM Calculation (commercial) are used to work out the energy performance of a residential dwelling or commercial building respectively, one target component of the SAP or SBEM Calculation  is air pressure testing that measures the air tightness of the dwelling.
