Smooth, deep-matt, super-white surface with high light reflection and light diffusion, which contributes to energy savings and a bright and comfortable indoor environment
Highest sound absorption/Class A sound absorption and highest fire safety (Class A1) Full range of dimensions and edges for complete design freedom A non-directional surface that reduces installation time and an anti-static surface that withstands exposure to worksite dust and enhances the product lifetime
Stone wool tile Visible side: smooth, deep-matt and super-white painted fleece Rear side: back fleece Durable painted edges
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.
Other performances
Room To Room Sound Insulation
Dn,f,w = 26
Room-to-room sound insulation Dn,f,w (C;Ctr) is measured in accordance with ISO 10848-2.
Reaction To Fire
A1 (EN 13501-1)
Reaction to fire is classified in accordance with EN 13501-1.
Light reflection and light diffusion
87% light reflection
>99% light diffusion
Light reflection expressed in % is measured in accordance with ISO 7724-2.
Visual Appearance
Super-white surface L value: 94.5. Deep matt surface, perfect in critical side-light Gloss: 0.8 gloss unit at 85° angle
The whiteness (L value) of the product is tested in accordance with ISO 7724 and measured on a scale from 1 (black) to 100 (white). The gloss of the product is tested in accordance with ISO 2813.
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
Enhanced durability and dirt resistance.
The surface of some ROCKFON products is specially treated to provide enhanced durability and dirt resistance.
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
