Raised floor systems, also known as access floors, are an elevated structural floor that is stabilized over a solid substrate, typically a concrete slab. A raised floor system creates a gap ideal for running electrical wiring and HVAC ducts.
The structural floor is composed of panels on a grid supported by adjustable vertical pedestals. The pedestals are affixed to the subfloor through either mechanical fixings or adhesives. Since the pedestals are adjustable, the gap between the elevated floor and the subfloor can be between 3 and 48 inches.
Panels are typically 2 feet by 2 feet and are normally composed of a cement or wood core clad in steel or aluminum. The panels are compatible with many flooring finishessuch as: vinyl, linoleum, laminate, rubber, carpet and stone or ceramic tiles.
Implementing value engineering and life cycle cost analysis will help find a balance between aesthetics, cost, durability and maintenance along with the purpose of the raised floor to determine what finishing materials are best-value options for the project.
Benefits of a Raised Floor Systems
The most common usage for access floors is to run cables, electrical wiring and HVAC ducts. Running cables and electrical wiring through the accessible space between the panels and the subfloor allows easy access and flexibility; wiring can be rerouted, repaired and upgraded without construction and minimal interference to the business’ everyday activity. When combined with modular electrical systems and modular walls, the entire building can be reconfigured in a fraction of the time it would traditionally take.
Heating and cooling a building with a raised flooring system is also more efficient. The empty space between the panels and the subfloor acts as a plenum chamber to dispense conditioned air evenly throughout the building. Additionally, since warm air rises, heating the building from the access floor gap during the winter is more effective and efficient.
Raised floors are particularly useful for data centers and telecommunication facilities. Computer systems can rest on perforated tiles so that conditioned air is accessible for each unit. The equipment can then be designed to draw the cool air from below.
With the increased efficiency and accessibility, access floors are an ideal alternative to suspended ceilings, pre-cast trunking and dado trunking.
Raised floor systems have been used in construction for several decades, originally developed to facilitate access to electrical and mechanical systems in commercial buildings. In recent years, raised floor systems have increasingly been used in data centers, educational institutions and other commercial buildings to support highly specialized equipment and to provide flexibility for future reconfiguration. These systems offer several advantages, but also present certain challenges in terms of maintenance and installation. This article provides an overview of raised floor systems, including the different types, their advantages and disadvantages, and their application in various industries.
If you’ve ever walked into a server room or data center, you may have noticed the distinctive elevated flooring. This is known as a raised floor system, which plays a critical role in supporting the complex infrastructure of modern technology. In this article, we’ll discuss what raised floor systems are, their history, and their various purposes.
Definition of Raised Floor Systems
A raised floor system is a type of flooring installation that elevates the surface off the subfloor. This creates an open space between the elevated surface and the subfloor, which can be utilized for a variety of purposes. Raised floors can be made from various materials, such as wood, steel, or cementitious panels.
History of Raised Floor Systems
The concept of raised floors can be traced back to the 1960s when they were first used to house computer systems. The early computer systems generated a lot of heat, and the raised floors were used to facilitate air circulation and provide a pathway for power and data cables. Since then, raised floors have become a standard feature in many industries, including healthcare, education, and finance.
Purposes of Raised Floor Systems
Raised floor systems serve a range of purposes, including facilitating air circulation, cable management, and providing access to systems infrastructure. They offer a flexible solution that can be easily adapted to meet changing needs. Raised floors can also be designed to provide acoustic insulation, seismic bracing, and fire resistance.
