One. Raised Floor Requirements
One. Raised Floor Requirements
Raised floor specifications begin with a minimum raised floor height of about four hundred to six hundred millimeters. In general, the higher the raised floor, the better the supply airflow.
Next, remember the suspended ceiling clearance from the ceiling slab. A practical guide is to set this at about one point five to two times the raised floor height. This extra space is important because beams and other utilities in the ceiling void take up room, and the plenum must still support proper return airflow.
Also remember the clearance from the top of the raised floor to the bottom of the suspended ceiling. A common minimum is about two point six meters. This allows enough space for a typical forty-two U rack, as well as lighting and fire suppression nozzles. If cable trays or other overhead services will be installed, more clearance should be considered.
