Air Tightness, Air Leakage and Air Pressure Testing For New Homes In accordance with building regulations in the UK, it is mandatory to produce measurements for air tightness for newly built homes. Tests to establish such figures go by various names: ▪ ▪ ▪ ▪

On completion of a build, a key component of our business is testing for airtightness. Testing for air permeability is critical for any build. Results affect a building’s energy performance.
What Are The Air Permeability Testing Building Regulations There are various factors affect air leakage testing, but as a rule of thumb, the target figure for new builds is 5m3/hm2 or under (air leakage rate/hour, for each square metre). This ‘pass or fail’ result is generated by a specialist engineer and indicates how much air is being sucked into a building — known as ‘leakage’— when the fan used to make such calculations functions at 50 Pascals.
