* for performance to AS1530: Part 4, duct constructed 52mm PROMATECT®-L500 boards, external fire (temperature measured
inside duct) FRL 120/120/60. For internal fire FRL 120/120/90. To obtain FRL 120/120/120, use 400mm wide collar. |
For selection of board thickness, it will not only depend on the required fire performance but also on the
internal cross section of the duct and the operating pressure(s). With large ducts and medium to high
operating pressures, internal stiffeners may be required. Please consult Promat if the operating pressure exceeds 1000Pa.
