Technical data
Sound absorption
Sound absorption data has been measured in accordance with ISO 354. Sound absorption data αp, αw and absorption class are calculated in accordance with ISO 11654. Noise Reduction Coefficient (NRC) is calculated in accordance with ASTM C423.
Fire performance
General
Rockfon products have a core of stone wool. Stone wool is non-combustible with a melting point of more than 1000°C.
Reaction to fire
Class A1 in accordance with EN 13501-1.
Fire protection
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 against European norm EN 13501-2 and/or national norms depending on requirements in national building codes.
Some sizes and edge details of Industrial Opal can be used with various RockLink grid systems to create a 60 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.
Humidity resistance and dimensional stability (flexural tensile strength)
Rockfon products are dimensionally stable even at humidity levels of up to 100% RH and can be installed at all temperatures ranging from 0°C to 40°C. No acclimatisation is necessary.
Industrial Opal is predominantly classified as class 1/C/0N in accordance with EN 13964. However, certain module sizes (width greater than 700 mm) are class 2/C/0N.
Light reflection
Thermal conductivity
Industrial Opal with a thickness equal to and exceeding 30 mm has been measured in accordance with EN 12667 and has obtained the following value: λD = 37 mW/mK.
Hygiene
Stone wool has no nutritional value and therefore it provides no sustenance to harmful micro-organisms.
Cleaning
The surface can be vacuum cleaned with a soft brush attachment.
Environment
A representative selection of Rockfon products have been awarded the Indoor Climate Label and the Finnish Indoor Climate label (M1).
Industrial Opal is recyclable.
