The gloss of the product is tested in accordance with ISO 2813.
Humidity And Sag Resistance Humidity And Sag Resistance Up to 100% RH.
No visible deflection in high humidity
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.
Surface Durability Surface Durability Enhanced durability and dirt resistance.
The surface of some ROCKFON products is specially treated to provide enhanced durability and dirt resistance.
Cleaning Cleaning Vacuum, Damp cloth
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.
Hygiene Hygiene Stone wool provides no sustenance to microorganisms
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
