Replacing glass in a fixed window

Has anyone ever removed the glass in a fixed window where it has rubber molding around it and can tell me how to do it ?

  • Agree with above, need thicker plywood. The window glass would most likely be 1/8 inch, possibly 3/16.

    The rubber molding is pushed in and locks in at the edge of the frame and you should be able to use a screw driver or awl at the seam to get it started. the hard part is the glazing tape that is on the inside of the glass, you should have a de-glazing tool to cut it away from the glass, a utility knife is a lot of work but might work for you. A de-glazing tool is similar to a pizza cutter, only designed to lay flat against the glass and push in to cut it. You will need new glazing tape to put in the new glass, or as some people do put a small bead of silicone all around the inside frame, put the new glass in and push the exterior rubber back in place.


    Thanks a lot. Much appreciated.

    Do you have any idea how thick the glass is ?

    What I would like to do is remove the glass and replace it with a piece of plywood the same thickness, (or close to it). Then make a cut out for a room size A/C unit

    Umm.. JW's advice is only good on certain fixed windows.

    SOME fixed windows the aluminum frame is wrapped around the glass, then welded or riveted together. That version has no removable parts without tearing apart the frame..

    As far as thickness goes, it WILL be much thinner than "plywood", I am guessing 1/8" to no more than 1/4".

    There is not going to be ANY substantial strength in that thin of material to hold a 50 lb - 60 lb A/C unit.

    My previous advice in another thread you started still stands.

    REMOVE THE WINDOW FRAME AND BUILD YOUR OWN FRAME WITH 2 x s AND PLYWOOD.

    The aluminum window frame is not really all that strong..
