What is Raised Floor?
Also called raised flooring, access flooring, or raised access computer flooring, a raised floor is a construction model in which an elevated floor is built above a building’s original concrete slab surface, thereby creating a hidden void between the two floors that is used for the passage of mechanical and electrical services.
There are two general types of raised floors:
The type of raised floor needed depends upon several considerations:
Let’s take a look at each of these raised floor types and what they are designed
A traditional raised floor used for underfloor air distribution
The Construction Specifications Institute (CSI) and Construction Specifications Canada (CSC) have designated the following Masterformat numbers and titles for this standard type of raised flooring:
The traditional post and panel raised access flooring system was introduced in the 1960s with the primary purpose of providing cooling and air flow to the large computer mainframes of that era, as they ran exceptionally hot.
A traditional access floor creates a sealed air space (called a plenum) between the raised access floor and the subfloor. The plenum is there to accommodate and contain underfloor air distribution (UFAD). These floors can be installed at a variety of heights, from 6 inches (152 mm) to 4 feet (1.3 m), or higher.
The height of the posts is dictated by the volume of cables and other services to be stored beneath the raised floor; the typical height is somewhere between 24 inches (610 mm) and 48 inches (1219 mm).
To meet industrial demands of low profile systems, traditional post and panel manufacturers have attempted to bring their raised floor heights, in some cases, down to four inches. However, at that height, post and panel flooring still doesn’t offer the usable space or flexibility that low profile systems have as a standard.
The key components of the traditional post and panel flooring system are as follows:
After installation, the floor panels can be covered with a variety of flooring finishes, such as carpet tiles, vinyl files, linoleum, high pressure laminate, rubber tiles, wood, marble, and stone and ceramic tiles.
Should repairs or changes need to be made to the services under the floor, a special tool and a trained worker will be required. This tool (called a floor-puller, tile lifter, or suction lifter) has a curved handle atop a large suction cup. To open the floor, the suction lifter is attached to an individual tile and then lifted with brute strength. For carpet tiles, a hook and loop lifter is usually used.
There are several things to consider when using a traditional raised access flooring system.
Structural problems, such as rocking panels or gaps between the panels, can cause significant damage to equipment—or even lead to the injury of personnel. It is vital to look out for problems like these by conducting regular inspections to check out the structural integrity of the flooring system. This practice will help identify and mitigate any problems before damage is done or people are hurt.
These types of problems can be mitigated if the installation process is done correctly in the first place. During installation, special attention must be paid to the condition of the subfloor. The subfloor should be clean of all debris and be as level as possible. And the walls surrounding the raised floor need to be as square as possible. This will minimize the need for cutting the panels, which, in turn, will minimize panel rocking and gaps.
Another thing to avoid is flooring that does not meet the load demands of the work space. Load ratings range from 1,000 to 25,000 pounds. The panels can be mixed by using lower-weight panels in the lighter load areas of the building, while using higher-weight panels in heavy load areas of the room.
In summary, traditional post and panel raised access flooring systems are a good solution when heavy duty systems like air distribution are required. Outside contractors or highly-trained inside personnel will be necessary to service these floors.
This flooring system does not provide easy access to the wires, cables, and pipes under the floor. The individual panels are heavy and require the use of a special tool to access the plenum. Also, it is not advisable to pull too many floor panels at once, as the entire floor can lose stability; this can be a major problem if you are several feet off the ground.
There are several other types of raised flooring systems available that are a little different from the traditional post and panel model. These primarily have a telecommunications/data center application.
In today’s world, raised access flooring is primarily used in IT data centers and computer rooms where there is a requirement for UFAD. All cabling and wiring are routed under the floor as well.
A telecommunications facility is usually made up of continuous lineups of equipment cabinets. These data centers often have the most populated installation configuration in terms of square foot area, and, therefore, the heaviest floor load anticipated for a raised floor system.
Moreover, data centers are often located in remote locations and are subject to physical and electrical stresses from sources such as fires and electrical faults.
In data centers, isolated air-conditioning zones are often associated with raised floors. Perforated floor tiles are placed beneath computer systems to channel cool air directly into them. In turn, the computing equipment is designed to draw conditioned air from below into the room. Then an air conditioning unit draws the air from the room, cools it, and forces it back beneath the perforated tiles of the raised floor, thus completing the cycle.
Traditional post and panel raised floors are not used in a telecommunications/data center environment. Several different types of raised flooring systems can be employed instead and are bullet pointed below.
