Plenum Testing

​​​

Why It Matters

A well-sealed plenum is essential for maintaining balanced air delivery, protecting system efficiency, and reducing unnecessary energy loss. Testing also helps detect leakage at joints, penetrations, and perimeter details before handover, reducing the risk of performance issues later on.

Our Service

We carry out plenum airtightness testing using established industry methods, with a focus on accuracy, reliability, and clear reporting. Where required, we can also assist with pre-test preparation and diagnostic smoke tracing to help identify leakage paths and support remedial works.

Best Suited To

Plenum testing is particularly valuable in high-performance commercial environments such as office buildings, data centres, and other spaces that rely on underfloor air distribution. It is an important part of delivering a system that is both technically sound and built to perform.

Plenum Testing

Plenum testing is a specialist airtightness service used to verify the performance of raised access floor voids that distribute conditioned air throughout a building. By measuring leakage rates and identifying weak points within the system, we help ensure the plenum performs efficiently, supports effective airflow, and meets the required design and compliance standards.
