Why are acoustics important?

Noise is an audible energy that can adversely affect ones physiological
and psychological wellbeing. The use of sound absorbing material reduces
sound reflection and will create a comfortable indoor climate.

Stone Wool Acoustic Tiles

Stone wool is by nature a highly sound absorbent material, bringing
excellent acoustic properties to our ceiling and wall solutions. This allows
you to achieve a high level of acoustic comfort while maintaining a high
level of aesthetics. The acoustic ratings of our products have been tested
by independent and accredited laboratories.

Acoustics is the science of sound

There are two main factors that determine the acoustics of a room:
-- Sound absorption: How sound behaves in a room
-- Sound insulations: How much sound travels from one room to another

The impact sound insulation between two floors is an expression
of the ability of a construction to insulate from sounds generated
by impacts e.g. footsteps, slamming doors. It is characterised by
the impact sound pressure level L’nT,w and is rated in dB. The lower
the value, the lower the sound pressure level, thus the better the
impact sound insulation. Some regulators prescribe maximum L’nT,w

How to compare
ceiling acoustics

To help you compare the acoustical
performance of different ceiling solutions,
the industry uses several indicators.

Sound insulation indicators:
How much sound travels from

Sundtkvartalet, Norway
Product: Rockfon Sonar dB 42 / Edge: A
16

Room-to-room sound insulation
The Dn,f,w value quantifies the longitudinal sound insulation provided by the ceiling between two rooms.
The higher the Dn,f,w value, the better the room-to-room sound insulation. The Dn,f,w value can be
considered equal to the previously-used Dn,c,w value. Dn,f,w is used by acousticians to predict the total
sound insulation DnT,w (R’w; DnT,A) between adjacent spaces.

Direct sound insulation
The direct sound insulation in dB indicated by the sound reduction index (Rw) measures the reduction
of sound passing through the suspended ceiling. Ceilings with high sound reduction index Rw will help
prevent noise generated by installations in the plenum from entering the room.

Room-to-room noise transfer through the ceiling. Noise from installations in the plenum is
significantly reduced by a ceiling with a
high sound reduction index (Rw).

17

Rockfon dB assortment – Maximise sound insulation
Our dB range has been designed to block sound from passing through the ceiling and as
such contributes to both high room-to-room and direct sound insulation.

What makes the dB range unique is that it provides a combination of both outstanding
sound insulation and sound absorption in one tile.
--d B 35 provides a quiet environment and sound insulation where privacy is not of great

importance
-- dB 41 is designed for spaces where concentration and privacy are important
--d B 43 and dB 46 provide a quiet environment and are designed for situations where

privacy and confidentiality are required

Our dB range includes class A sound absorption with up to 46 dB sound insulation.
Our sandwich technology used in dB 46 range combines:

1 A sound-absorbing front panel 3
which absorbs sounds 2
and thus lowers sound 1
pressure levels for a
quieter environment.

2 An air-tight membrane which prevents sound to migrate to an adjacent room for
higher privacy and confidentiality.

3 A sound absorbing back panel which captures sound in the plenum due to light
fixtures and other open installations which create sound leakage.

Rockfon dB products
Rockfon dB products perform best in class with a combination of high sound absorption and high sound
insulation.

In combination with vertical sound barriers (stone wool based products placed on top of partition walls)
and/or extra absorbing (stone wool) material in the plenum, Rockfon dB products can maximise sound
insulation in very demanding situations (see table below). Moreover cap silencers installed above light
fixtures and other open installations absorb transmitted sound, thus improving sound insulation.

Fire performance

Stone wool is the safe basis of all our ceiling tiles
and wall panels. It is made from basalt rock which
is by nature non- combustible.

Rockfon has invested heavily in fire testing and
related developments. Most of our ceiling tiles and
grids are rated the safest possible - A1.

Reaction to fire

The EU Reaction to Fire evaluation criteria (EN 13501-1) measure
a material’s ignitability, rate of heat release, rate of spread of
flame, rate of smoke emission, toxic gas emission, flaming
droplets/particles and/or a combination of these safety aspects.

A1 is the highest classification. A1 products do not contribute
to the development and spread of fire. They generate neither
smoke nor flaming droplets. Most of our ceiling tiles and grids
are rated A1.

Fire resistance

This term indicates how well a building construction can hold
back fire and prevent it from moving from one room to another
for a stated period of time.

It measures three criteria:
– R:L oad bearing capacity - to provide strength and stability of

the building
– E: I ntegrity - to keep the element intact
– I: Insulation - to keep the temperature low on the unexposed

side of the material

The fire-resistant properties of stone wool and metal grids
ensure that our ceilings provide the safest fire protection Class
A1.
A range of Rockfon systems are classified in accordance with
European Norm EN 13501-2 and/or national norms, proving
their fire resistance performance.

21

Humidity and
sag resistance

In buildings under construction which are not yet
hermetically sealed or where materials have not dried out,
moisture problems can occur. Additionally, in wet rooms
such as swimming pools, kitchens and sanitary areas,
humidity levels can be exceptionally high.
Humidity can weaken the structure of certain ceiling
materials and cause them to sag. In extreme cases, they
may even fall out of the grid. Equally, corrosion of metal
parts can provide a hazard that should be avoided by
installing suspended ceilings with enhanced corrosion
resistant (ECR) grids.

22

Rockfon ceiling tiles are dimensionally stable at up to 100%
relative humidity and can be installed at temperatures ranging
from 0°C to 40°C. No acclimatization period is necessary, and
Rockfon ceiling panels can be installed in the early stages of
construction (when the windows are not fully sealed) without any
risk of distortion.

Their lightweight, yet stable non-hygroscopic character,
minimizes the final weight of the fully-installed ceiling that also
reduces the number of hangers needed for their installation.
In accordance with EN 13964 our Chicago Metallic™ grid
assortment is classified in four classes of grids,- A,B, C, and D-
with B being the standard in regular conditions such as office,
retail and schools. For environments with a high relative humidity
(>90%) and high risk of condensation, Class D grids should be
installed with Enhanced Corrosion Resistance.

All Rockfon products come with a 15-year
product guarantee. For more information
and conditions, please contact your local
representative.

Light reflection

Poor lighting can result in eye strain, fatigue and
aching, which in turn is likely to lead to deterioration
in performance, particularly if the work relies on visual
equipment, such as computer-based job roles. As this
type of work is now common place, the importance of
lighting for visual health and performance at work is likely
to become increasingly important. Light is important to
our wellbeing and performance.

The quality of modern artificial light has improved, but
the most comfortable and economical light still comes
from the sun, although not sufficient and often combined
with artificial light. As a result, not only the amount of
light, but also the quality of light is important. Both
need to be adapted to the working circumstances in a
room. The light reflecting capacity of a ceiling will not
only contribute to a reduction in electricity bills, but will
also improve the quality of lighting conditions. Next to
sunlight and artificial light, we can make a distinction
between direct and indirect light. Direct light will light
directly, whereas indirect light is the result of light
reflection. As the ceiling is the only surface in a room that
is completely visible, the light reflection should be as
high as possible to make effective use of the light.

A ceiling with the right combination of high light
reflection and a good spread of light (light diffusion)
leads to a uniform and accurate spread of light in a room,
leading to a reduced need for light fixtures.

Cleaning

All our ceilings can be cleaned with a
vacuum cleaner fitted with a soft brush
attachment.
Selected ceilings, like Rockfon Blanka,
with a micro-textured surface can be
cleaned using a damp cloth or sponge.
Rockfon MediCare Plus and Rockfon
MediCare Air products have a durable,
highly water-repellent surface that resists
diluted solutions of ammonia, chlorine,
quaternary ammonium and hydrogen
peroxide. They can also be disinfected
twice a year using steam cleaning
following a protocol defined by experts
and using an adapted surface mop.
For more information on the cleaning
properties of our products, please refer
to product datasheets.

Hygiene

Our ceiling tiles are made of water-repellent stone wool. Stone
wool provides no sustenance to the following microorganisms
(tested in accordance with JIS Z 2801:2000, ASTM C 1338-96 and
NFS 90-351:2013:

--Escherichia coli
--Staphylococcus aureus
--Methicillinresistent staphylococcus aureus (MRSA)
--Stachybotrys chartarum
--Penicillium brevicumpactum
--Alternaria tenuissima
--Aspergillus Brasiliensis
--Sporobolomyces roseum
--Rhodotorula rubra

The Rockfon MediCare range offers four levels of hygienic
performance (Rockfon MediCare Standard, Rockfon
MediCare Plus, Rockfon MediCare Air) designed to meet the
requirements of zones with different levels of infection risks in
healthcare facilities.

All Rockfon MediCare products meet low particle emission
requirements and have a clean room classification of ISO Class 5
or better (ISO 14644-1).

Impact resistance

Along with sound absorption, the impact resistance
of construction materials is an important issue in
schools and gyms. Ceilings in these kinds of areas
need to be able to withstand tougher-than-average
wear and tear, as well as frequent demounting.

The impact resistance of suspended ceilings is
tested according to EN 13964:2014 annex D and
evaluates the total ceiling system (tiles and all grid
components). It defines three impact resistance
classes:

--C lass 1A ceilings should be installed in any sports
hall where heavy-impact ball sports are played.

-- Class 2A ceilings can be installed in sports
centres where low-impact ball sports are played
and in heavy-duty school areas.

--C lass 3A ceilings can be installed in rooms
where the ceiling must fulfil basic requirements
on impact resistance e.g. classrooms, school
corridors.

The test procedure for impact resistance indicates
the ability of a ceiling to resist the incidental impact
of balls under normal conditions in sports halls.

Rockfon Boxer ceilings feature a reinforced
surface giving them superior mechanical resistance.

Thermal insulation

Better insulation of buildings is a profitable way to
reduce the CO2 emissions; it is a low hanging fruit in
combatting climate change. Insulation reduces today’s
unnecessary waste of fossil fuels from buildings that
are responsible for 40% of the EU and US energy
consumption and a major contributor to man-made
CO2 emissions. The developing countries - struggling
with energy poverty and air pollution – also has a need
for buildings that waste less energy and emit less CO2.

Although we are primarily designed for acoustic
solutions, there are also situations where the
benefit of the intrinsic thermal insulation capacity of
ROCKWOOL base material, as a major component of
Rockfon ceiling tiles, can be used efficiently.

This is the case when shopping malls build over
parking garages as well as in flat-roof buildings or in
old buildings with cold cellars. The Rockfon ceiling
needs to be seen as part of the total thermal insulation
solution taking into account building physics (e.g.
condensation, avoiding thermal bridges, etc). We
provide products specially designed for thermal
insulation in combination with acoustic absorption.

CE marking

Customers need to be able to trust the declared performance of ceiling
manufacturers and that is exactly the purpose of CE marking. The European
Committee for Standardisation (CEN) introduced the EN 13964 norm for
suspended ceilings which has been mandatory since 1st July 2007.

The norm aims to make it easier to compare suspended ceilings. To
achieve this, it defines those product characteristics which can or must be
declared on product labels and in product documentation. In the interest of
maximising the information we provide to our customers, we have selected a
considerable number of parameters that are now declared for each of our CE
marked products. We not only declare the mandatory properties, Reaction
to Fire and Emission of Formaldehyde, but also sound absorption, flexural
tensile strength, durability, thermal insulation, as well as informing customers
on values for light reflection, impact resistance and sound insulation when
relevant.

All of our relevant ceiling tiles have been CE marked since October 2005,
across all our factories in Europe. In addition, we have chosen the highest
level of attestation and verification conformity AVCP1. This means that an
independent certification organisation – Belgian Construction Certification

Applications

Healthcare

Our stone wool ceilings are the ideal choice for healthcare environments.
It provides no sustenance to harmful microorganisms. In addition, our
ceilings provide the winning combination of light reflection, humidity
resistance, sound absorption, fire protection and easy cleanability.

Education

All our ceilings deliver excellent fire safety and sound absorption performance
that are perfect for both new build and renovation projects. For sports and
high activity level areas, we also offer reinforced impact resistant products.

Office

When sound becomes noise, people become stressed and irritated. Rockfon
stone wool sound absorbing and insulating solutions are crucial to improve
speech intelligibility and aid confidentiality. They also contribute to a healthy
indoor environment which can increase productivity levels in your offices.

Commercial

Good acoustics can have a positive effect on customers buying habits. Our solutions
improve acoustics and the wide range of sizes and colours help to personalise the design
concept with welcoming indoor environments which are easy to clean and maintain.

Leisure & Sport

With large numbers of people in one space, acoustics and fire safety are an important
consideration. Our impact-resistant ceilings and wall panels are ideal for sports halls,
gyms and other high activity level areas. Our ceilings are dimensionally stable at up
to 100% relative humidity resulting in ceilings that won’t sag or bend over time.

Industry

The needs of industrial buildings vary depending on the nature of the business.
The unique performance of our products contribute towards hygienic, lighting,
fire safety and sound absorption requirements. Plus, products such as baffles
and islands can be installed where a traditional suspended ceiling is not suitable.

Ceiling tiles & wall panels

Our acoustic stone wool solutions are divided into four categories to
better guide you through our assortment. Grouped according to their
unique properties, they all contribute to innovative acoustic solutions.

Monolithic Ceiling
Our monolithic surface solution offers the visual aesthetics of gypsum
while conferring the unsurpassed acoustic properties of stone
wool. Available in standard white or colours, it provides a seamless
appearance that is suitable both for ceilings and for walls.

Modular Ceilings
Our standard modular ceilings are grouped into five sub-categories
ranging from our most extensive ceiling offering in the Design White
category to the Basic White category that is the obvious choice if you
are looking for a standard ceiling solution. If you are looking to spice
up your design with some color the Design Decoration category is the
place to look and if you want to offer a high quality acoustics combined
with popular edges and dimensions our Core White category can be the
answer. Our Special Application category covers ceilings with anything
from enhanced cleaning properties to impact resistant products for
leisure facilities.

Islands and Baffles
Sometimes a traditional modular ceiling is not the answer and then an
acoustical island or baffle can be the solution. Our frameless acoustic
islands offer excellent sound absorption and come in a variety of shapes
and colours. Our baffles offer a flexible solution to noise control in a
wide range of spaces. Used in sets, baffles offer effective functionality
and durability when unhindered access to services is required.

Wall absorbers
Our wall absorbers enhance sound absorption and assist acoustic
ceilings in creating an optimal acoustic space. Our wall absorbers are
available with a variety of design features, including impact resistance,
colored surfaces and perforated metal encasings.

D-edge

Use D-edge to create a concealed grid ceiling while
retaining access to the ceiling void. Its design allows for easy
installation and demounting.

X-edge

X-edge tiles can be suspended on a grid or can be mounted
directly on the soffit by using direct fixing brackets. The bevel
between the tiles is smaller than the D-edge, so you can
achieve a more seamless looking appearance. X-edge tiles
accommodate the elegant integration of standard HVAC and
lighting elements. Each X-edge tile is demountable.

with either T15, T24 or T35 profiles. The grid system is less
dominant with the narrower T15 profile. A-edge tiles are
demountable.

AEX-edge

AEX-edge is used in combination with other edges, for
example a D-edge, which when used with a bandraster grid
accommodates movable walls.
