The supporting panel of the raised floor
It is the panels that make the flooring modular; for years they were available only in the 60x60 cm format, but the market now offers panels in different formats too (120x60, 60x40) permitting greater liberty in design.
The principal components of the supporting panel are:
- lower finish which serves to protect the panel from damp. It is possible to use a 0.5 mm galvanised steel tray or a 0.5 mm galvanised steel sheet, which will also improve mechanical performance (it is not present in monolithic panels)
- support which may be made of a variety of materials. It is the core of the system, supporting loads on the floor by distributing them over the structure below, it is the supporting surface for the upper finish and with it constitutes the walking surface
- perimeter edging made of self-extinguishing rubber, serving for lateral protection of the panel and identification of the point of contact and transmission of horizontal stress.
Types:
Homogeneous sulphate panels
These panels are made of calcium sulphate and high density fibres permitting improvement of load-bearing capacity. The lower surface of the panel, which is 42 mm thick, is covered with 0.05 mm aluminium foil and edged with self-extinguishing, non-creaking plastic material.
High density wood conglomerate panels
These panels consist of a high density wooden conglomerate core bound with poly-hardening resins. They are 38 mm thick and are finished with 0.5 mm galvanised sheet steel on the inside and 0.05 mm aluminium foil on the outside.
