Ontario building code and greenhouses
I am trying to build a greenhouse in Ontario Canada. When I contacted the building inspector, he said that the code required any windows in a heated structure to meet strict heat loss requirements. This would include the glazing in a greenhouse.
From what I could tell reading the code itself, even regular double pane glass would not qualify. It would have to have some additional treatment as well. (not that I could afford double pane glass anyway)
I could meet the requirements (come to the right heat value) with double wall polycarbonate and one or two layers of plastic, but I am not sure if I can do this. I do have lots of old windows, but I can't just triple pane them myself because each window does not have a rating.
I can't ignore the building inspector. Not only am I visible on his way home from work, I am building on the site of a building that he forced the former owner to take down when it was almost completed (he had no permit).
Does anyone have a way around this ?
