Large area of unframed double glazed panels
A friend in Southampton is having a conservatory roof removed. The panels on the roof are roughly 8ft long and around 2ft6in wide. They have eight of them, all a handful of years old, all in near perfect condition, no misting, etc.
My instant thought was that they'd make a perfect greenhouse (with wooden ends) and with pretty minimal framing.
They're either going into a skip or someone can collect them free of charge from Southampton. My friends would be pleased to see them used rather than discarded.
