Polycarbonate Roofing

[BadDad]

My shed has a curved roof with corrugated polycarbonate fitted during frosty weather the interior is always dripping with condensation, three questions.
1. if I fit triple wall polycarbonate on the roof will this resolve the problem of the condensation.
2. Can I fit triple wall to a curved roof the radius of the curve is 3 meters or maybe more difficult to measure, the corrugated poly was fitted quite easily.
3. Is there a flexible joiner to go between the sheets available to fit to the curve.
Thanks for any assistance.
