Is 1/4 inch (6 mm) plywood, glassed over, adequate for a non
load-bearing, hard canopy for my little cruiser? The canopy will be
about 9ft long by 6ft wide, and slightly curved for water run-off and
aesthetics. How many layers of fibreglass cloth would be needed?


It should be fine. I did consulting work for UL in the late sixties
while married to my third wife, who was the CEO for Anderson lumber
international at the time.
