GEOTEC® Vertical smoke extraction and ventilation duct

The ducts are made by juxtaposing GEOTEC®S boards 1000 mm long and 30 or 45 mm thick. These systems are available for fire classifications EI 60 to EI 120: fire stop 1 to 2 hours, according to EN 13501-3 and EN 13501-4 standards.

All the boards are moulded to standard dimensions with a rebate on all four sides for 45 mm thick ducts and on two sides for 30 mm thick ducts, to facilitate their assembly.

Each segment of length 1000, which can be cut to length, consists of four or more boards.
GEOTEC® ducts can also be made with GEOTEC®SX boards 1000 mm long and 1200 mm wide for 30- or 45-mm thickness. These single dimension boards do not have longitudinal rebates for easy cutting and assembly.

System advantages

  • Assembly by screwing, stapling and using the “polochonnage” solution (mixture of sisal fibre and glue)
  • Light-weight materials
  • 100% natural gypsum-based products and CE certified
  • Ease of installation and time saving
  • Compatible products including RftAldesFrance Air and Panol
