Why Raised Floor?
Hardly any work place today is
imaginable without voluminous computer and communication systems. Also
air-conditioning, ventilation and lighting systems become more and more
extensive. Due to new developments in the office- and communication
technique, constantly changing organizational patterns as well as common
changes in the utilization of rooms, higher demands are being placed on the
flexibility of the access flooring systems. Today, the access floor as a
solution to the various technical and aesthetic demands on the market
receives and ensures investments through quick amortizations.
Access floor systems offer:
·
Maximum flexibility; maintenance,
installation and conversion projects can be executed quickly,
·
Floor can be walked on immediately,
·
Pre-manufactured components parts for dry
assembly,
·
Easy access to all areas of the
communication and in-house technique. Non-destructive, without noise, dust
and interference of the workflow,
·
Optimum amount of spare room for future
modifications,
·
Optimum space for large dimensioned air
conditioning units, extinguishing systems, and electrical distributors.
The important criteria for choosing an access floor
system are the: load-bearing capacity, fire protection, electrostatic
behavior and sound absorption.
Load-Bearing capacity
The expected point load determines the
requirements for the load-bearing capacity.
The nominal point load of a panel is the decisive value for the valuation of
the load-bearing capacity
Fire protection
When talking about fire protection we
distinguish between building material class and
fire resistance class. The building material class (for example B1) only
values the single panel;
the fire resistance class takes the whole system into account.
The value F30 for example guarantees
that the whole system will resist a fire in the cavity for 30 minutes.
Electrostatics
Electrostatics loads are generated
through friction. Those are not only unpleasant for people
but can also affect the function of many electronic devices. The right
choice of floor covering
in connection with the access floor system provides for the discharge of the
loads over
the grounded access floor construction.
Q: What
types of Floor Panels are available?
A: Hollow steel, Cementitious filled steel, Concrete filled steel and
wood-core (particle board), Calcium sulphate, aluminum systems are
available.
Q: What type
of system should I use in a Computer Room?
A: That would depend on the loading being imposed on the floor and
the amount of deflection at the design load your project may require. The
Industry standard has always been to specify a concentrated load rating at a
maximum deflection of .080". However, for the greatest performance a
concrete filled steel system in a rigid grid understructure should be
specified. This offers optimum loading at .100" deflection with excellent
Rolling and Impact loads. Today most users have switched to the concrete
filled steel panel due to its increased performance. See Performance Charts.
Q: What
finishes are available for use in a Computer Room?
A:
HPL (high pressure laminate) is the standard used in most computer rooms.
Some projects require a conductive vinyl or conductive HPL.
Q: What
product should be used in a general office application needing a raised
floor for Wire Management?
A: For an office application a concrete-filled product in a
corner-lock application is best. Senway offers several load ratings which
allow you to tailor the system to the projects needs.
Q: What type
of system is best used in a Clean Room application?
A: An all aluminum system is best used in a clean room application.
Grates or perforated aluminum panels are used due to the requirement for
Laminar Air Floors.
Q: What is
the lowest height I can install for access flooring?
A: 2-5/8" is the lowest finished floor height. However, since most
concrete slabs aren't perfectly level, a minimum of 4" is recommended.
Q: Are
Computer Floors only used in certain types of projects?
A: Originally they were only installed in computer rooms. However, in
the past 15 years they have evolved into the general office area and are now
being designed into a project throughout the facility. Office buildings,
schools, hospitals, Internet facilities and libraries are a few of the
applications utilizing access flooring.
