Air pressure testing – also known as air tightness testing or air permeability tests – measures how much air is escaping from a building.
When you’re undertaking a new residential or commercial development, you’ll need to make sure there isn’t too much ‘air leakage’. Air leakage is when air escapes through the fabric of the building via uncontrolled means. This could be through gaps around windows, sockets, or where the external wall meets the floor.
Air Permeability Tests with UKBC
UKBC offers ATTMA accredited air permeability tests for residential and commercial buildings. Our service includes:
Air escaping can cause cold draughts and heat loss. Improving the air tightness of a building will lower your heating bills and improve the energy efficiency of your property. Therefore, it’s important to be confident your building is sufficiently airtight air pressure testing.
Furthermore, you are required by law to make your development is sufficiently airtight. Air pressure testing is required by Part L1A and L2A (England & Wales), Section 6 (Scotland) or Part F1 (Northern Ireland) of The Building Regulations. Air pressure testing has been mandatory for all new build residential and commercial properties in England, Wales and Northern Ireland since 2006, and in Scotland since 2010.
You should carry out air pressure testing when your project is near completion. This is so you can make sure the building meets or exceeds the air permeability rating specified in your design stage SAP or SBEM calculations.
