The Air Testing Plenum Process
An Air Tightness Consultant will visit your site to carry out a Plenum Test. The Plenum Testing process includes:
• Removing a floor tile from the plenum and connecting a tunnel to a fan, once all air handling ducts serving the test zone are turned off, isolated, and temporarily sealed.
• Once the area has been prepared and correctly sealed, the air tightness test takes place, including taking several pressure readings.
• The specification for the plenum is usually determined by the project’s Mechanical Engineer. We’ll need to understand the specified pressure (e.g. 0.5l/s/m2 @ 50 Pascals).
We recommend an on-site visit as soon as the floor is in place to ensure Plenums are correctly sealed for testing. If you’ve already failed a plenum test, we can provide remedial advice post design, ensuring you pass your next plenum test.
