GEOFLAM® Horizontal fire rated ductworks
The fire rated ductworks 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 rabbet on both sides for 35 mm thick ducts, to facilitate assembly.
GEOFLAM® FX boards are single dimension and do not have longitudinal rabbets for easy cutting and assembly in the case of 3 hours fire rated ducts installations: EI 180S.
