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:
- A substructure, consisting only of pedestals of different lengths,
designs and loading capacities, or of pedastals in combination with
stringers.
- 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.
