did you install the 100pct plastic or the composite??
i have been looking into the 100pct plastic (ecoboard and carefree) for a 5000 sqft deck. my builder has already built the flooring, 12'' offcenter and every other stud is doubled. all he is waiting for is my choice of material. he is a bit worried that with expansion and contraction, the screws will somehow loosen after a period of time. we are in long island new york, so if its installed at 75 degrees, this should limit the expansion.
anybody have experience with pure plastic... good/bad??
