Design of a raised floor

Thinking and conceiving a raised floor

The path followed by the designer when requesting a raised floor is the following: the first choice is related to the type of covering which is intended to be used. The surface finish is the element that more than any other can affect or enhance the aesthetic value of the environment. Having made this first choice, the designer proceeds to a technical evaluation which consists in searching for the type of panel that best meets the functional requirements of the project. The choice of the panel is not influenced by the structure but by the evaluation of requirements such as: impact noise, resistance to loads, compatibility with the chosen coating.


Maintaining the same dimensions over time
As we know, wood is sensitive to fire and humidity, it is a good rule to carefully evaluate the raw material and check that it has a certain density. The optimal solution is achieved with panels in inert material, characterized by high density and weight such as to minimize the drum effect.

Sound absorption
To achieve a good level of sound absorption, the combination of panel / covering must be optimized.


Based on the available height
If it is reduced, one is obliged to favor a structure without cross beams, to recover the space of the cavity as much as possible.

Minimum height
5/8 cm are sufficient for housing classic systems (telephone, telematics, plumbing, electricity).

Need height 30 cm
When the underlying compartment also serves as a plenum for air conditioning distribution. In these cases it is better to favor a heavier structure with mechanical fixing. Availability for the design and construction of any higher height. Possibility of creating special structures with heights from 100 to 200 cm.

Based on load resistance
It becomes a decisive choice criterion when setting up a technological environment, in which exceptional loads are often expected. In these cases the structure assumes a decisive value while the coating does not have to perform aesthetic functions as well as antistatic.


In this context, the raised floor becomes the tool for:

  • completely transform and update the system of pre-existing systems
  • solving the location of the systems especially for particular and too delicate structural situations, do not recommend direct actions on the structures
  • insert, if the height allows it, not only the pipes of the heating system but also the heating element itself
  • to redistribute the water network and toilets.


In this case, the choice of how the raised floor will be used becomes fundamental. The height of the floor, and therefore the height of the inter-floor, depends on which technological systems will be housed inside. In a new design it is possible to rationalize the use of the raised floor in established areas and solve the problems of connection with other systems and other materials.
