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.

| Fire Resistance | The fire resistant properties of stone wool ensure Rockfon ceiling tiles provide fire protection in construction. The fire protection properties of Rockfon ceilings have been tested and classified in accordance with European norm EN 13501-2 and/or national norms depending on requirements in national building codes. Some sizes and edge details of Rockfon Koral Tenor can be used with various Chicago Metallic grids and Rockfon systems to create a 30 minutes fire protecting ceiling in accordance with BS 476 Part 21 and Part 23. They can also be used to create a 30 minutes fire protecting membrane ceiling (integrity only) in accordance with BS 476 Part 22. | |
|
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.

| 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 | 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.
