How low can a raised floor height be constructed and still use UFAD?
A. We believe that UFAD systems can go as low as 6″ FFH (4-5/8″ of clear space) to 8″ FFH provided our column units are spaced in frequent points on the floor plate to ensure good air distribution. This low FFH is very applicable for general office where electrical plug and play conduit is only 7/8″ diameter and voice and data cables are not intensive. The floor height needs to be greater for applications where cable trays are being used.
