What is a raised floor?
The raised floor so called raised flooring, and access flooring. This floor is a production model which we built in a building that has an elevated floor. The original material piece surface, between the two floors, creates a hidden annulled that is used for the passage of automatic and electrical facilities.
Two general types of raised floors:
- Standard/Traditional Access Floor (Post and Panel Raised Floor)
- Low Profile Access Floor (Cable Management Floor)
A traditional raised floor
This raised floor is used for flooring air distribution. These post and panel-raised access system was introduced in the 1960s. Its main purpose is providing cooling and airflow to the large computer processors of that period, as they ran tremendously hot. Between the raised access floor and the subfloor, a traditional access floor creates a sealed air space called a plenum. To accommodate and contain underfloor air distribution the plenum is used. A traditional access floor is installed at a variety of heights, from 6 inches (152 mm) to 4 feet (1.3 m), or higher.
The post height is dictated by the volume of cables and all other services to be kept underneath the raised floor. The classic height is somewhere between 24 inches (610 mm) and 48 inches (1219 mm).
Traditional post and panel manufacturers have tried to bring their raised floor heights, to meet the industrial demands of low-profile systems. Post and panel still doesn’t deliver usable space or elasticity at that height.
There are components of the traditional post and panel flooring system are as follows:
Post (platform): This is a vertical, adjustable post that supports the floor panels. At each corner, the panel is attached with screws to a steel post (4 posts per panel). With an epoxy resin-based adhesive and with mechanical constituents the posts are usually bonded to the subfloor.
Stringer: adding lateral floor support this is a horizontal piece of hardware that connects to the post head. When a floor is raised enough for a person to crawl or even walk through, additional structural support and lighting are often needed. Added necessities may contain fire destruction systems and cable tray systems.
Low Profile Raised Floor
Low Profile Raised Floor is called Cable Management Floor. The post and panel raised floor have been seen as a raised floor and it still serves the same purpose today for over 50 years. Still, modern building requirements changed rapidly and dramatically with the explosion of information technology and audio-visual innovation of the early 21st century. In this systems there was a need for an alternative approach.
For traditional posts and panels, low-profile is not a replacement if the purpose is for underfloor air distribution. For cable management, low-profile is a flexible and adaptive solution in those applications where air distribution is not a concern.
After installation of the raised floor panels can be covered with a variety of finishes, such as vinyl tiles, carpet tiles, linoleum, rubber tiles, and high-pressure laminate, wood, marble, and stone and ceramic tiles.
