I am in the early stages of designing a new greenhouse. In one of my current greenhouses the roof is double wall polycarbonates and I occasionally get a few condensation drips. Not a lot, but enough that I don't want it to happen again if I can avoid it. I am considering using triple wall for the roof of the new greenhouse. Can anyone tell me if I would be likely to have condensation with the triple wall? Also, is there degree of slope where the condensation will all run down rather than having a stray drip here or there?
