2.1 – TOP COVERINGS
There are different types of floor coverings available, but not all of them are suitable for raised floor.
This is due to the following reasons:
• the dimensions: since an access floor module is 60 x 60 cm, it is not possible to manufacture with
coverings of smaller dimensions. It is also not advisable to use coverings whose dimensions are not
compatible with the floor module, because of waste excess and/or an unsuccessful final design (for
example studded rubber with module differing from 60 cm).
• not all materials are suitable for being glued to an access floor panel, such as certain floor spongebottomed
carpets; other materials can not even be cut successfully, such as certain bouclè carpet,
because they fray.
ELECTRICAL CHARACTERISTICS
What ever concerning may be, PVC, needle-punch carpet, plastic laminate etc., coverings possess transversal
electric insulation characteristics, (through their thickness), known as electrical resistance. The unit of
measurement is ohm (Ω).
If this value is >1x10 9 ≤2 x 10 10 Ω, we talk about antistatic coverings, if the value is ≥1x10 7 ≤1x10 9 Ω we talk
about static-dissipative coverings, and if the value is >1.5 x 10 5 2 x 10 10 Ω, such as parquet or
some kinds of rubber, but these coverings are not suitable for computer rooms or electronic instrument rooms.
