Guidelines and warnings
The STIFERITE Fire B8 panel is classified as Broof T2 and can be installed on both sloping and horizontal surfaces.
The STIFERITE Fire B8, STIFERITE GT3 and STIFERITE GT4 panels are suitable for the application of an additional bituminous sealing layer with a slate-effect finish, applied by flame-bonding; whereas in the STIFERITE GT5 panel, the bonded bituminous sealing layer already has a slate-effect finish.
For guidance on the method of fixing the panels, please refer to standard UNI EN 11442.
