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.

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 | |
|
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. |

A24
A24-edge tiles are a cost-effective solution that provides easy access to the installations hidden behind the ceiling. Tiles with an A-edge are also the perfect complement to concealed and semi-concealed ceilings (e.g. when used as a perimeter trim). They can be mounted in T24 grid systems. A-edge tiles are demountable.
