We have a fairly substantial, and ancient, greenhouse in our garden. Base size is twelve feet by ten, but the apex roof is twelve feet by eight, because the two long sides slope inwards twelve inches each side from floor level. Construction is fairly solid galvanised metal (steel?).
The problem is that it is in the corner of the garden, and the local scrotes love nothing more than chucking apples over the wall, and breaking the glass.
It occurred to me to replace the glass in the roof (2 by 2 panes) with sheets of ply, cut into two ft. squares. To be honest, it is used as a shed rather than a greenhouse, so the loss of light would not be a problem. I'm not sure about the additional weight, though. We are in NE Scotland, and there is often a foot or more of snow on the roof, so
9mm ply, or 12mm? Is this practical?Thanks.
