I have a number of timber sash window which have their original single-glazed glazing.
As a consequence, although some of the windows are close to the floor, none of them have safety glass. In order to retain these windows I would consider installing secondary glazing.
If I installed the secondary glazing, what are opinions on retaining or replacing the existing glass?
When the secondary glazing is opened, then the exposed primary glazing is exposed and therefore still potentially dangerous if someone fell into it.
If the primary glazing is changed to a single-glazed pane of toughened safety glass (not heavier laminate), would this imbalance the weights? I'm unsure as to whether modern safety glass is heavier than old single glazing, though I imagine it is.
