Reaction to fire is classified in accordance with EN 13501-1.
The stone wool core of ROCKFON products is non-combustible with a melting point of more than 1000°C and provides fire protection. Some ROCKFON ceilings have been tested and classified in accordance with European norm EN 13501-2 and/or national norms.
Light reflection expressed in % is measured in accordance with ISO 7724-2.
ROCKFON ceiling tiles are dimensionally stable even at humidity levels of up to 100% relative humidity and can be installed at all temperatures ranging from 0°C to 40°C. They can be installed during the very early stage of the build (when windows are not fully sealed). Their lightweight yet stable non-hygroscopic character minimises the final weight of the fully-installed ceiling. ROCKFON ceiling tiles are predominantly classified as Class 1/C/0N in accordance with EN 13964. Certain module sizes (width above 700mm) are Class 2/C/0N.
The surface of some ROCKFON products is specially treated to provide enhanced durability and dirt resistance.
Vacuum:
The surface can be vacuum cleaned with a soft brush attachment.
Damp cloth:
The surface can be cleaned using a damp cloth or sponge with a slightly alkaline detergent (pH between 7 and 9) without alcohol, ammonia or chlorine. This may render the surface slightly shinier, so we recommend cleaning the entire surface evenly.
Stone wool provides no sustenance to the following microorganisms tested in accordance with JIS Z 2801:2000 and ASTM C 1338-96:
– Escherichia coli
– Staphylococcus aureus
– Methicillin-resistant staphylococcus aureus (MRSA)
– Stachybotrys chartarum
– Penicillium brevicumpactum
– Alternaria tenuissima
– Aspergillus niger
– Sporobolomyces roseum
– Rhodotorula rubra
Microbiological class M1 fulfilling the requirements of Zone 4 (very high risk) defined by NF S 90-351:2013. Tested with:
- Methicillin Resistant Staphylococcus Aureus (MRSA)
- Candida Albicans
- Aspergillus Brasiliensis
The bactericidal and fungicidal effect of dry steam cleaning meets the requirements of NF EN 14561 (> 5 log10) and NF EN 14562 (> 4 log10), meaning the disinfection is very effective.
Clean room classification is measured in accordance with ISO 14644-1.
