Raised access plenum floor
A raised access plenum floor is a floor with a 'void between a building’s floor structure and the occupied space. In such floors it is important that conditioned air in a floor plenum flows into the occupied zone and does not leak into cavities, risers, stairwells, heating trenches or other adjacent zones. A properly sealed raised access plenum floor will allow the diffusers and grilles to fulfil their primary role of delivering air at the correct flow rate. The airtightness of raised access plenum floors can be a serious energy efficiency issue.'
