6 fire PERFORMANCE General: Rockfon wall absorbers have a core of stone wool. Stone wool is noncombustible with a melting point of more than C. Reaction to fire: Samson, Scholar, Sonar Activity, Polar Colour: Class A1 in accordance with EN Fire protection: The fire resistant properties of stone wool ensure Rockfon wall absorbers provide fire protection in construction. impact resistance Samson has been tested for mechanical impact resistance while directly mounted in System Samson and meets the requirements of impact resistant in accordance with DIN Part 3. This classification confirms the safety of this and provides an indication of the s capability, however, it does not confirm the s ability to maintain consistent visual appearance if impacted on a regular basis. HUMIDITY RESISTANCE AND DIMENSIONAL STABILITY Rockfon ceiling tiles are dimensionally stable even at humidity levels of up to 100% RH and can be installed at all temperatures ranging from 0ºC to 40 C. No acclimatisation is necessary. light reflection Samson: Rockfon white 72%; Scholar: Rockfon white 89%; Sonar Activity: Rockfon White 85%; Polar Colour: Rockfon White 84%, Dakar 59%, Graphite 16%, Grey 59%, Night Blue 4%, Oasis 62%, Ocean 60%, Red 9%, Savanna 70%, Black 4%. Diffuse light reflection in accordance with ISO THERMAL CONDUCTIVITY Samson, Scholar, Sonar Activity: with a thickness equal to and exceeding 30mm have been measured in accordance with EN and have obtained the following value: λ D = 37 mw/mk. Thermal resistance: R = 8 m 2 K/W. hygiene Stone wool does not contain organic nutrients and does not allow growth of harmful microorganisms. clean room classification Sonar Activity is classified as Class 5 in accordance with ISO cleaning The surfaces can be vacuum cleaned with a soft brush attachment. Scholar and Sonar Activity: The surface can also be cleaned once a week using a sponge or cloth and warm water (max. 40 C) with a slightly alkaline detergent (max. ph 10) without alcohol, ammonia or chlorine. Cleaning with a damp sponge or cloth may render the surface slightly shinier and we therefore recommend cleaning the whole surface evenly for best results. After care The tiles can be treated with Rockfon finishing paint, PVA waterbased special paint with safety 001, applied in the correct amount with an airless spray with good capacity. The surface of the tiles must be clean and dry and the existing paint surface must be firmly adhered to the tile prior to refinishing. Heavily discoloured tiles should be replaced. The painting of acoustic tiles reduces the sound absorption by approximately 10%. environment A representative selection of Rockfon products have been awarded the Indoor Climate Label and the Finnish Indoor Climate Label (M1). All Rockfon wall absorbers are recyclable.
