Sheet Thickness Criteria and Table
Note: Regardless of the support configuration selected, the sheet should
always be installed so that the rib structure channels are sloping downwards.
Sheet "width" is the dimension perpendicular to the rib structure, "length"
the dimension parallel.
tables indicate the maximum allowable sheet at a specified loading which
results into an acceptable sheet deflection behavior while minimizing the
RISK of the sheet buckling (negative load) or pop-out effect calculated with a safety
factor of 1.5.
N.B. The values indicated in sheet manufacturer tables are generally applicable for a
Multiwall sheet edge engagement in the glazing frame of at least .75
For sloped glazing applications a minimum slope of 10° (2 in/1 ft sheet
length) is advised to allow for rainwater drainage. See each multiwall
sheets manufacturer's load data for precise information.
