The new range of Rockfon ceiling tiles developed for bandraster profiles
provides you with even more design freedom. The use of bandraster profiles
enables the creation of flexible interior environments where partition walls can
be installed according to the needs of the building users at any time, without
compromising the ceiling expression. This makes for efficient use of open plan
office space, “white space”.
Rockfon Sonar tiles for bandraster profiles are also well suited for corridors where long

materials, the ceiling tiles are transformed into a high performance composite
providing enhanced room-to-room sound insulation. This solution is the
obvious choice in offices and meeting rooms where privacy is of the essence.
Sonar Silence solutions are also well suited for use in many applications, especially
education buildings, which incorporate light weight roofs. Their use enables
compliance with Building Bulletin 9 ambient noise levels in the event of rain, thereby
enhancing BREEAM credits, as well as contributing to appropriate reverberation times
and speech intelligibility

The sound insulation properties of Sonar Silence 8 have been measured in a laborato-

particularly walls and ceilings. Sound insulation has been measured in accordance with
ISO 10 / 9.
When tested in a construction with a 6 dB dividing wall, Sonar Silence 8 provides a
Dnc,w of 8 dB.
FiRE PERFORmANCE
General - Rockfon Sonar Silence 8 is made from 100% stone wool - resin bonded
mineral wool - which can withstand more than 1000°C for more than 120 minutes
without melting.
Reaction to fire - Class A1 in accordance with EN 101-1, the safest possible class.
Meets with Essential Principle 1 of InFiReS Design Guide thereby contributing to a safer
and more insurance friendly building.
Humidity RESiStANCE ANd dimENSiONAl StAbility
(Flexural tensile strength)
Rockfon ceiling tiles are dimensionally stable, even at humidity levels of up to 100% RH.
As the humidity inside the building has no influence on Rockfon ceiling tiles, the ceiling
can be installed at all temperatures ranging from 0ºC to 0ºC and no acclimatization
is necessary. Rockfon ceiling tiles retain their superior properties even in infrequently
heated and unheated rooms. However, in accordance with best practice building
design, precautions should be taken to avoid condensation risks.
Rockfon Sonar Silence 8 is predominantly classified as Class1/C/ON in accordance with

ROCkFON SONAR PRODUCTS
HyGiENE
Stone wool does not contain organic nutrients and so is not attacked by rot, fungi or
bacteria. This makes for a cleaner and healthier indoor environment.
ClEAN ROOm ClASSiFiCAtiON
Sonar and Sonar Silence 8 are classified as ISO in accordance with ISO 16-1.
ClEANiNG
The Sonar surface is easily cleaned with a moist cloth. Use alkaline cleaning agents and
do not use high concentration spirit, chlorine or sal ammoniac. The surface may also be
vacuum cleaned with a soft brush attachment up to 2 times/year.
HANdliNG/StORAGE
Sonar products are lightweight and easily handled. Due to their inertness and
dimensional stability no special storage or handling requirements are necessary. Please
see our general handling/storage guidelines for detailed information.
Sonar products are ideally suited for fasttrack development and can be installed at an
early stage in the building program due to the inherent stability of the 100% stone
wool. Rockfon tiles can be easily cut using a sharp knife.
