"After reading other reviews, I was prepared for a construction nightmare, but good planning and common sense made building the greenhouse straightforward. Using the correct polycarbonate silicone is important, I used it during building, and in all the glazing joints afterwards. Yes the polycarbonate will flex in the wind..... Its 4mm polycarbonate...! But my greenhouse is rock solid. Winter storms might change that, but replacing sheets will be easy. Of course, 35years experience in construction helped my project, but this greenhouse is good quality, and I'm very happy with it."
