Sound absorption is measured in accordance with ISO 354.

Sound absorption data αp, αw and absorption class are calculated in accordance with ISO 11654. Sound absorption properties of islands and baffles are quantified by the equivalent sound absorption area Aeq expressed as m² per item.

Product Specifications

Reaction To Fire Reaction To Fire A1
Reaction to fire is classified in accordance with EN 13501-1.
Light reflection and light diffusion Light reflection and light diffusion 86%
Light reflection expressed in % is measured in accordance with ISO 7724-2.
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.
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 – Rhodotorula rubra
Environment Environment Fully recyclable stone wool
Indoor Environment A selection of Rockfon products have been awarded the Finnish M1 emission classification for building materials and the Danish Indoor Climate Label for low emission products
