Is is possible to install additional glazing over an existing window?
I live in NW Ontario, Canada fairly cold climate. I have an existing house built in 2009-10. It is built on a sloping lot facing south with a proux front made up of mostly windows. The glazing installed is dual pane with low E and argon, there was a mistake and the wrong glazing was sent. Orginally some of the south facing glass was to be tinted to help reduce glare, however clear glass was sent and due to our remote location and the time involved to get the replacement glazing the windows were installed as is. The replacement tinted glazing is here, it will be switched with the existing glazing, my questions are:
1. Can the removed clear glazing now be installed either on the exterior or the interior of the replaced glass?
2. Will the installation need to be completely sealed or should it be vented?
3. Is there a recommended spatial separation between the glazing units?
4. Finally, is it worth while to even attempt this?
