Fire protection of service ducts and shafts

The protection of service ducts and shafts, 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 180.

They can be manufactured as desired:

      • By means of GEOTEC®S boards in the same way as for GEOTEC® ventilation and smoke extraction 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.
