🚪💨 Blower Door vs Pulse Air Testing – What’s the Real Story?

As the construction industry pushes towards net zero homes and higher energy performance standards, the tools we use to measure airtightness must be both accurate and representative of real-world conditions.

🔹 Blower Door Testing

Pressurises a building to 50 Pa to measure air leakage.

Requires the property to be vacated and sealed during testing.

Can be disruptive and time-consuming.

Independent research by Leeds Beckett University found that in semi-detached and terraced homes, blower door tests can overestimate leakage by around 20% because the pressure forces air into adjoining properties.

This can result in homes being unfairly labelled as “leaky” and even lead to inappropriate ventilation strategies, increasing the risk of damp and mould.

🔹 Pulse Air Testing

Uses a short burst of air at low pressure (~4 Pa), closely matching real-life conditions.

Delivers accurate results in under 15 seconds.

Non-intrusive – no need to vacate the property.

Less affected by inter-dwelling leakage, making it more reliable for terraced or semi-detached properties.

Suitable for new builds, retrofits, and occupied homes.

📊 With evidence showing that blower door tests may misrepresent performance in certain housing types, Pulse Testing offers a credible, accurate alternative.

At AVT UK, we provide both methods – but we see Pulse Air Testing as the future of airtightness measurement in homes where shared walls can distort results.
