The intelligent design of modern buildings requires highly flexible solutions that meet both architectural and functional requirements. Today, modular raised floors are a normal part of the fit-out in modern offices and public administration buildings.

Raised floors” are industrially prefabricated floor panels and pedestals that are installed by a dry construction method. Any of the panels freely supported on the pedestals can be taken up to access the floor cavity.

The reliability and the simplicity of the raised floor construction make it irreplaceable for the banks, offices, computer centers, power centers, airport dispatch centers and other areas with exclusive equipment standards.

Not only can electrical installations be accommodated in the floor cavity, but also water, waste water, pneumatic tube conveyors, compressed air, central vacuum cleaning systems, etc.

Originally, the raised floor construction was created for wiring closets, transformer stations, offices, etc. – places where easy access to the equipment was needed without interrupting operations.

A decisive advantage of raised floors is that they can also handle airconditioning tasks, such as ventilating via swirl diffusers, or with higher requirements for ventilation and airflow, via entire ventilation panels.

With the Hyperline access floor system, finished floor heights up to 1250 mm (49.2”) can be achieved as a standard, and greater heights upon request (as, for example, is necessary for auditoriums and control rooms).

Raised floors are made up of two main parts:

  1. A substructure, consisting only of pedestals of different lengths, designs and loading capacities, or of pedastals in combination with stringers.
  2. Raised floor carrier panels consist of various materials and floor coverings in a grid of 600 x 600 mm (23.6” x 2 3.6”) (special sizes also available upon request).
The basic element of the access floor construction is panels mounted on height-adjustable supports that make it possible to hide all the engineering and technical lines and the defects of the main floor. In addition, the panels can carry heavy loads and provide an easy access to the flush-mounted equipment.

The access floor panels differ in material, thickness, and inner and surface coating types. A wide range of combinations makes it possible to use the access floors in a wide variety of facilities depending on the current load, fire safety requirements, frictional electricity absorption or, alternately, on the requirements of the antistatic properties.

The standard panel dimensions are 600 x 600 mm (23.6” x 2 3.6”). Covering of 10.76 ft2 (1 m2) will require 2.78 pcs. of panels. Custom-made panels of nonstandard sizes are also available.

Upon request, the coating of the access floors may be linoleum, PVC, laminate, parquet or carpeting for offices, bars or cafes; or anti-static vinyl coated for technical facilities, electrical centers, or telephone offices. The type of the coating is determined according to the design of the facility and its purpose. Thus, for computer halls, wiring closets and laboratories, vinyl coating with good conductivity is used. For offices, carpeting may be used. More expensive and wear-resistant coatings are ceramic tiles, marble, granite, wood.
