Hi - I am reusing some old frendch doors from a verandah that have colonial glazing bars as part of a renovation. The doors will be installed inside the house. They are about 50 years old so I know dont have safety glass in the panes. Should I replace the panes with safety glass?. Does it depend on the size of the panes of glass - if so, how big can the panes of glass be before I need replace them with safety glass ?
