Used the original framing just removed the plastic and added metal,[/QUOTE]
In your original version, what's protecting the chimney? Rigid insulation? Something else?
I've not gotten past the temporary wind walls we put up with plywood. Nothing protected more than 4' high and nothing overhead. All the posts I hear about what people have done and I think I'll get there some point. But, I boil in the middle of our yard every year. I think I could manage the framing and plastic sheeting.
