The Company
TOPFLOOR group is an European leader in the field of raised access floor production.
The company was founded by a group of technicians in 1986. It grew up in time and now it has two highly automated production lines, one
specialized in standard panels and the other in encapsulated panels: with more than twenty five years of experience TOPFLOOR group is able
to offer the most wide and innovative range of raised systems on the market. During these years the company produced more than four
millions of square meters of raised floor and exported in 25 nations.
The research on different typology of products and special finishes generated a new concept of raised floor finally suitable even for those environment traditionally not considering the use of this system. Innovative productions lines, Italian design, together with a careful pre and post
selling service guarantee high quality and total reliability.
All the TOPFLOOR products are made in Italy as the manufacturing plants are in Carsoli (AQ), 50 km far from Rome.

Raised Access Floors
Flexible Space
Modern office environment requires flexibility and accessibility. Raised access flooring is used to meet these requirements by creating a
plenum space where high concentrations of power/data cabling and other mechanical services can be concealed under the walking
surface. These subfloor services remain easily accessible due to the modular design of the raised access floor system, thus providing
flexibility for quick and easy layout changes, installation of new equipment or repair and maintenance.
Product applications
The evolution in the raised floor industry has widened the application range from the original computer areas to bank counters, expo stands,
shopping centres, hotel halls, pubs, hospitals, surgeries, industrial production sites, data processing centres, clean rooms, recording studios,
casinos, dance floors stages, bowling alleys, museums and in the restoration of historical sites. Nowadays, raised floors can be also used in
modern houses where domestic innovations need a continuous evolution of layout.

ENVIRONMENTAL RESPECT AND LEEDTM CERTIFICATION
Green Design
Green design has a strong positive impact on public health and environment, reducing at the same time operating costs, enhancing building
and organizational marketability, potentially increasing occupant productivity and helping to create a sustainable community. Through an EcoDesign approach it is possible to integrate and control environmental aspects directly at the design stage, considering the whole life-cycle of
construction sites, from the purchasing of raw materials to the production and final disposal of materials.
What is LEEDTM
LEED (Leadership in Energy and Environmental Design) is a rating systems developed by USGBC to evaluate the impact of buildings on
people’s lives and on the health of the planet. Since 1999 the LEED Green Building Rating System for New Construction has been helping professionals to improve the quality of buildings and their impact on the environment.
LEED promotes a whole building approach to sustainability by recognizing performance in five key areas of human and environmental health:
sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.
LEED system is voluntary, consensus-based, market-driven, based on accepted energy and environmental principles, striking a balance between
established practices and emerging concepts.

EUROPEAN STANDARD EN 12825
This European Standard, approved by CEN, got the status of a National Standard so that within 5 years from its approval any project in CEE would have to
comply with it. From February 2007, this standard is the only one that governs the characteristics and performance requirements of raised access floors for
internal finish of buildings, allowing full access to the services in the plenum.
It is applicable to modular, factory made flooring elements, comprising panels and pedestals, and defines their methods of testing and measurements.
The ultimate load is the main criterion of classification. This is the value measured at the failure of the component during a specific ultimate load test with a
point load of 25mm x 25mm.
The elements subjected to the procedure have to meet the following criteria:
– before the element collapses, it has to withstand the relevant ultimate load for its class, given in table 1.
– when the load applied is equivalent to the working load, which is the ultimate load divided by a safety factor, the deflection has not to exceed the value of
table 2.
TOPFLOOR usually applies Safety Factor 2 and 2,5 mm of deflection. Any technical specifications is in accordance to these values.
Reference tables
Pedestal vertical load bearing capacity
The substructure has to support 4 times the working load of the tested system.
The pedestal can’t be distorted or damaged.

Dimensional deviations
The panels of a raised access floor has to be manufactured with dimensions
which enable their interchangeability. Deviations of dimensions have not to
exceed the values given in table 3 for one of the appropriate classes.
Reaction to fire
Where required, the raised access floor has to be classified for its reaction to
fire according to prEN 13501-1. Where the procedure allows to test a representative portion of the raised access floor, this is done in accordance with the
requirements of the method (i.e. for the positioning of joints). Where it’s not
possible, testing and classification is evaluated on the performance of each
component and/or materials of the raised access floor. In this case, results for
the raised access floor are based on the reaction to fire classification of each
component and/or material. Where materials or components may be classified,
without testing, in reaction to fire Class A1, it is declared in advance.
Electrostatic conductivity
The elements comply with EN 1081, EN 1815 and HD 384.6.61, where relevant.
Acoustic insulation
When required, the impact and/or airborne sound insulation of the raised
access floors is tested in accordance to EN ISO 140-12.

Corner Lock System
GW series are also available with a “Corner Lock” option, a system
which allows the fastening of each panel to the pedestals heads by
means of self-tapping screws.
The system offers:
- maximum rigidity and stability even at the highest finished floor,
without additional stringers.
- protection from unauthorized access to the underfloor area.
- maintenance of structural properties even in case of special servicing or alterations of the fixtures and fittings in the underfloor area.
The drilling on the 4 corners is made by CNC machines assuring the
best possible calibration and interchangeability of every single element.

Wood essence floorings, with an high aesthetic value, are suitable for representation office, both for office and commercial centers; particular
attention is to give both during storage, installation and use, due to the sensibility of the wood to temperature and humidity variations. Natural
wood is also sensible to change of color (oxidation) depending on the exposure to the light. It is important that, after the installation, the
relative humidity range is between 40% and 60% as, outside these values, wood structure can present deformations.

Guide to the choice
The choice of the suitable raised access floor system depends
firstly on the intended use, as for office spaces, housing or technical rooms.
Panels and floor coverings
The first criterion of selection is the working load: it is advisable to preliminary check the comparison table
(pag 16 - 29). The load classes from 3 to 5 efficiently fits
most of functional requirements. The load class 2 is more suitable to non-permanent loads whilst class 6 is normally used
for areas with specific and extremely high load requirements.
At the same time, it is necessary to choose the most suitable
finishes for the intended use, to be compatible with the
desired type of panel (pag. 31-36).
In general, within the wide range of choice, it is advisable to
use stone or ceramic finishes in high traffic areas, such
as corridors, lift entrances and halls; moreover these finishes
can also be applied in all those office or housing spaces with
an a high profile appearance. Resilient materials (PVC,
rubber, linoleum) can be used for almost all operational office
spaces.
About wood, the extremely natural beauty of the essences
has to be preserved by a careful use, particularly focusing on
humidity control and maintenance, in total absence of water.
It’s possible to use the bare encapsulated GW panels
as walking surface, along with possible variations in stainless steel, to fit specific minimalist or hi-tech aesthetic and
architectural choices. It can be successfully applied with no
particular restrictions in modern offices, show-rooms, display
areas and shops.
A further element to evaluate in the panel/covering matching
process is the flexibility of use along with an optimal site management feature offered by the magnetic loose-lay
tiles. In this case, the bare faced steel encapsulated floor can
be first installed on site, leaving the option to loose-lay the
desired final covering at a later stage, without using adhesives,
thanks to the magnetic layer of the tiles. The final coverings/finishes will so avoid all the potential post-installation damages
caused by working operations during the building process of
the site. Furthermore the choice of loose-lay covering can be
customized area by area, even at different times and without
interfering or operating on the main steel encapsulated raised
access floor. The total flexibility also involves format and design, allowing future variations at low costs. The magnetic
loose-lay tiles is perfect to developers wishing to offer, in business or commercial centres, finishing solutions that are tailored to the end-users or easy-to-change destination of use.
Substructures
The type of substructure to match the chosen panel/covering
mainly depends on the height of the finished floor; for floor
heights up to 300 mm pedestals only (TF3/SA) can be used
with all the panels; in case of heights over 300 mm it is always
advisable to use stringers (substructure type TF3/ST1 - TF3/ST2
- TF3/SH - TF2/50S) to ensure the correct lateral stability. The
choice of the substructure changes the total supported load of
the system, particularly for not encapsulated panels. The final
choices can be made according to the specific comparative
cards (pag 16 - 29). Only for GW panels, as an alternative to
stringers or to guarantee a better protection of the subfloor
plenum, a “corner lock” (pag 30) system can be put in place,
with the panels screwed to the pedestals heads.
Acoustic requirements
Density and weight of the materials determine significant variations of the acoustic properties. Calcium Sulphate raised
floor systems, especially those with calcium sulphate core, have
high soundproofing features. Care must also be taken in the
choice of the final floor covering (textile, resilient, stone or metallic) as it can determine variations of the acoustic performances. It is also possible to provide the system with special acoustic
pads to apply under the base of the pedestals for a general improvement of the acoustic performances, if required. Due to
the complexity of this subject, it is recommended, if in doubt,
to consult our Technical Department.
Antistatic characteristics and conductivity
Problems due to electrostatic charges generated on the floor
surface can be avoided by an appropriate choice of the materials.
In particular, antistatic and/or conductive coverings (laminates,
textiles, PVC, etc.) with electrical resistance ranging between
106 and 1010 Ohms, can be chosen depending on the intended
use of the area, applied with conductive adhesive.
Resistance to humidity
Raised access floors can notoriously be sensitive to sudden changes of temperature or to high relative humidity rates. First, a correct use, from storage to maintenance and cleaning of the raised
access floor system is needed. In case, for instance, of constructions like high raise buildings or skyscrapers, where many months
can pass before the air conditioning is fully functioning, or in
geographical areas like the Middle or Far East, characterized by
high temperatures and humidity, GW panels are the perfect
choice, both with chipboard or especially with calcium sulphate
core.
One of the main characteristics of TOPFLOOR is the high degree
of specialization and experience on field: our Technical Department
is always at your disposal at [email protected] where all the design
specifications will be analysed in details to identify the best
panel/covering/substructure that can fit all the requirements.

38
Installation and maintenance
Site preparation
In case of newly constructed buildings, the screed / subfloor must be
free of moisture and properly cured (for at least 2 months if made of
traditional concrete). The screed must be free of debris or dirt and sufficiently flat, treated with anti dust sealants.
Windows and door frames must be in place and all other trades must
have finished their work (i.e. installation of ceilings, ducts/piping, electrical fixtures, plastering, cladding, curtain walling, etc.) and removed
their equipments at least 24 hours prior to starting the raised access
floor installation.
Services must be finished before the installation starts and must be situated following the designed positioning in the pedestal grid. The
grid must have previously been traced on the subfloor with paint so
that ductworks, piping, cabling or obstructions do not interfere with
the raised access floor substructure pedestals. Services should not be
placed in close vicinity of perimeter walls or columns in the room. The
layout of the above mentioned grid must allow, where possible, for
perimeter cut panels at least 15/18 cm wide for stability and aesthetic
reasons. It is good practice to check with a rotating laser that doors
thresholds and/or other traditional floors areas are all levelled at the
same height.
Installation
After having verified the conditions before mentioned, it’s necessary
to clean the subfloor and coat it with inalterable, anti-dust, polyurethane or epoxy paint. This treatment, always advisable, is absolutely
necessary is the plenum between the screed and the raised access
floor is used for air conditioning. It is important to determine carefully
the staring point for the installation, taking as reference of the structure
two orthogonal axes and laying out the control lines verifying their
accuracy with the Pythagorean Theorem (see table). While the installation proceeds, it is very important to keep checking the levelling of
the system by means of spirit levels, levelling bars or rotating laser devices.
Moving heavy equipment (safes, heavy filing cabinets, etc.) must be
carried out by using spreader plates or special trolleys to spread the
weight onto the raised access floor system and, at the same time,
avoiding damaging the floor coverings.
It is mandatory to attach the pedestals to the subfloor by means of
adequate adhesive and pedestrian traffic can only be allowed after at
least 12 hours from the installation. Installation of floor accessories

Storage
Immediately after offloading, the materials must be stored for at least
24 hours in a dry area, protected from bad weather conditions, preferably in an environment at temperatures ranging between 5°C and
35°C and relative humidity between 40% and 70%.
i.e. electrical and data outlet boxes should be done following the
layout specified in the contractor’s shop drawing. The installation is to
be completed with all the required accessories.

Substructure with stringers
The installations starts from the point before determined. Once the
installation of the structure is finished, it is necessary to regulate the
general height with spirit levels, levelling bars or rotating laser devices.
When everything is plain, the panels can be posed, starting from the
first internal row of the two orthogonal axes.
Substructure without stringers
If the structure is without stringers, it is necessary to fix the support to
the ground with adhesives. Supports and panels are simultaneously
posed and verified with spirit levels, levelling bars or rotating laser
devices each time. Before posing this type of floor, it is necessary to wait
24 hours to let the adhesive that fixes the supports to dry.
39
Side cut-outs and last installations steps
It is suggested not to have short portions of panels in contact with
the perimeter of the room. If in the modular partition there are two
different portions of panels at the limits (i.e. one of 55 cm and one of
15 cm), it is better to sum up the two measures and after divide it in
two equal parts (55 + 15 = 70 cm, 70 / 2 = 35 cm).
In the final stage, steps, flights, vertical closing and other accessories
are installed. Once the floor is completed, it is always suggested to
protect it with cardboard or polyethylene foils until the setting up of
the room is completed.
Installation time
The time needed to install TOPFLOOR raised access floor depends
on the dimensions, the shape, and the accessibility of the rooms,
the type of the panels and their coverings and the substructure. A
team of two people can install from about 30 m2 of floor a day, in
small surface rooms, to more than 90 m2 a day in medium or big
surface rooms as trimming and posing perimeter panels takes a lot
of time and accuracy.
40
Use and maintenance
Cleaning should be done only by means of vacuuming
or using specific equipments for this purpose. Water
must not be used directly on the floor surface as this
might cause delamination of the panel covering and
eventually swelling of the panel itself, especially when not
using steel encapsulated chipboard core panels. Washing
of the surface can be carried out only by strictly following
the directions given in the maintenance technical data
sheets or after consulting our technicians.
The cleaning methods vary according to the chosen
covering materials. On some resilient coverings
(linoleum, PVC), wax treatments should be applied to
optimise the day-to-day and scheduled cleaning operations.
Our Technical Department will be pleased to be of
assistance for any clarification required.
For structural safety and for the safety of its users,
dismantling or replacement of panels (i.e. when
installing new services in the floor cavity) should be carried
out by lifting only alternate panels at a time, avoiding to
create canals or isles of empty spaces, to maintain the
correct alignment of panels.
