Description

White, stone wool micro-textured surface ceiling tile with high sound absorption.


Fire performance:

The fire resistant properties of stone wool ensure Rockfon ceiling tiles provide fire protection in construction.


  • Tested and classified in accordance with EN 13501-2 and/ or national norms depending on requirements in national building codes.
  • Some sizes and edge details of Rockfon Koral™ can be used with various Chicago Metallic grids and Rockfon systems to create a 30 and/ or 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. Consult manufacturer for details.


Humidity resistance and dimensional stability:

  • Dimensionally stable, even at humidity levels of up to 100% RH.
  • As the humidity inside a building has no influence on Rockfon ceiling tiles, the ceiling can be installed at all temperatures ranging from 0-40ºC. No acclimatisation is necessary.
  • Retains superior properties even in infrequently heated and unheated rooms.
  • Precautions should be taken to avoid condensation risks.
  • In accordance with BS EN 13964, predominantly classified as class 1/C/0N. Certain module sizes are class 2/C/0N.

Cleaning:

  • 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).

  • Attractive surface finish.
  • Easy to clean with a vacuum or a damp cloth.
  • Available in semi-concealed and visible grid options.
