I have 2 questions regarding installing corrugated fiberglass panels over a porch deck.
The 4' x 10' panels will be screwed into perpendicular 2” metal tubing at 3-foot intervals.
Can the screws be applied to the peaks of the panels without “closure forms” (wavy stuff) or are the closure forms necessary?
The location of the panels makes it impossible to “curl” them in order to reach where the screws need to go. Can a sheet of plywood be placed on top of s corrugated fiberglass panel support the weight of the installer without causing too much expansion or damage?
