Raised Floor

A raised floor, also raised flooring, access flooring, or raised access computer floor, provides an elevated structural floor above a solid substrate, often a concrete slab, to create a hidden void for the passage of mechanical and electrical services.

Raised floors are widely used in modern office buildings, and in specialized areas such as command centers, IT data centers and computer rooms, where there is a requirement to route mechanical services and cables, wiring, and electrical supply.

In data centers, isolated air-conditioning zones are often associated with raised floors. Perforated tiles are traditionally placed beneath computer systems to direct conditioned air directly to them. In turn, the computing equipment is often designed to draw cooling air from below and exhaust into the room. An air conditioning unit then draws air from the room, cools it, and forces it beneath the raised floor, completing the cycle.
