Fire rated ductworks

The fire rated ductworks, classified according to the EN 13501-2 standard, allow the protection of gas pipes, medical fluids, various pipelines or electrical cable trays up to a fire exposure time of 3 hours: EI 180S.

They can be manufactured as desired:

      • By means of GEOTEC®S boards in the same way as for GEOTEC® fire rated ducts.
      • By means of GEOFLAM®F boards in the same way as for GEOFLAM® ventilation and smoke extraction ducts.
      • By means of GEOFLAM® C – Light channels for cross-sections up to 350 x 200 mm.

System advantages

  • Assembly by screwing, stapling and “polochonnage” possible (mixture of sisal fiber, plaster and glue)
  • Lightweight materials
  • 100% natural gypsum-based products
  • CE certified
  • Ease of installation
  • Time saving
  • Compatible with Rft products
