Notes:
It appears that 1/16" thick plastic could be used if edges are reinforced (ie. framed). See canopy at BCIT.
The total weight will be somewhere around ??? pounds and the moment arm will be around 40 inches.
General:
Use 1/16" thick plastic (acrylic?). Compound curvature gives strength.
Approximately 5.6 sq.ft. (810 sq.in.") = 2 pounds.
