The outer panels are triple wall polycarbonate with a 1/2" space between the outer panels and the inner twin wall panels. The roof is corrugated polycarbonate panels with polycarbonate sheets on the bottom of the rafters. They were added later to create a dead air space for insulation purposes.@R2elk I love your greenhouse. It's even a great winter porch area!! I've been wanting to enclose my back porch in a similar way. Morning sun on back and southern exposure on end. Those pictures just spark my desire again. Dang you!!
My porch is a 3' raised, sand filled, brick outer and concrete poured on top, for the floor surface. Sounds like a heat sink storage area. wood rails and posts. I think there's possibility!
The proof that the roof dead air space works is that snow can be on the roof and the temperature in the greenhouse can be in the 80°s without the snow melting.
A fan driven ventilation system is a requirement. Without it the summer temps will be unbearable.
