Air Tightness Testing

Pulse Air Tightness Testing – Precise Low-Pressure Measurements for Retrofit Applications

At Yorkshire Energy Solutions Ltd, we offer expert air tightness testing for existing buildings using the advanced Pulse testing method. Our experienced team identifies air leaks and assists with energy-efficient retrofitting, fully complying with PAS 2035 – Pathway C standards.

Why Air Tightness Testing Matters

Air tightness testing is crucial for determining the amount of conditioned air (heated or cooled) that leaks from a building through gaps and cracks in its thermal envelope. Simply put, it reveals how drafty a property is—impacting energy costs, indoor comfort, and the performance of insulation and ventilation systems.

The Pulse Method – Low Pressure, High Accuracy

Unlike conventional blower door tests, Pulse Air Tightness Testing employs low pressure to replicate real-world conditions. This provides a more precise assessment of the building’s performance during everyday use.

Our equipment is capable of testing:

• The entire building envelope, including all doorways

• Individual rooms, when needed

This method is fully approved under the Part L Building Regulations in England and Wales and is recognised as a compliant test under PAS 2035 retrofit standards—making it a smart and regulation-ready choice for your retrofit project.

Supporting Smarter Retrofit Design

Air tightness test results play a crucial role in shaping both ventilation strategies and energy-saving measures. Whether you’re at the planning stage or post-installation phase, our testing service supports informed decisions and long-term performance.
