The duct panels may be cut in either width or length direction taking in consideration the duct’s dimensions and the material usage.
In order to optimize the duct’s mechanical characteristics and fully utilize the panel (minimal waste), different cutting methods may be employed, each with its own limiting dimension
The following are three examples of the cutting and installation methods suggested, others may be found in the Fabrication Guide.
w + h + w + h < 1040 mm
The duct’s dimensions, length(l), width (w) and height (h), determine the cutting and installaation method of the duct.
w + h + w, o h + w + h < 1080 mm
w + h < 1160 mm
