Hi
I am currently building a lean to roof, however i cannot decide what the beat dimensions would be for the polycarbonate sheets.
The area is 3m long and 5.4 m wide.
I was thinking to buy the sheets 3m long and 1.3 m wide, and fix them using aluminium glazing bar on the sides.
I only want to have vertical rafter and no other wood in the middle to support them.
Will a 16mm triple wall polycarbonate sheet hold at this size, 3m long and 1.3 wide without middle support, or is it too wide?
What would the maximum width be without a middle support? Many thanks
