GEOFLAM® Horizontal smoke extraction and ventilation ducts

The ducts are made by juxtaposing GEOFLAM® F-Light boards 1000 mm long and 35 mm thick or by assembling GEOFLAM® FX boards of a single size: 1000 x 900 mm (W x L) and 50 mm thick.

These systems are available for fire classifications EI 120 and EI 180: 2- and 3-hour fire resistance according to EN 13501-3 and EN 13501-4. All GEOFLAM® F-Light boards are moulded to standard dimensions with a rebate on both sides for 35 mm thick ducts, to facilitate assembly.

GEOFLAM® FX boards are single dimension and do not have longitudinal rebates for easy cutting and assembly in the case of 3 hours fire resistant ducts installations: EI 180.
