    Default How to Remove Broken Pane of Glass from Aluminium Window Frame

    OK, good weekend. Broke the glass in the bottom half an aluminium window frame. I believe it is a sash window.
    After some reading am I right to assume that the entire window frame must be removed from the wall in order to replace the broken bottom pane?
    There are four screws holding the entire frame into the surrounding block wall but I am not sure if the windows have any screws in them or they clip together
    The glass appears to be held in place by a rubber seal/strip but I think the glass goes further behind this and behind some of the frame.
    Obviously I can pull out the rubber strip but would I think the entire window still needs to be removed?
    Any suggestions?

    A brand name of the window would help !

    The aluminium frames I have worked with just had the rubber strip to hold the glass in, they were sliding windows not sash.
    Would not expect glass replacement would require frame out.

    Thanks. If I knew brand I would have definitely said. I'll look at pulling rubber out and see what happens.

    FWIW... frame out in my experience is not required. Removing the rubber strip will allow the glass to be removed, especially as it's broken.
    The exact size of the replacement glass is the key. Usually fed into a top corner first then sat down into the bottom of the frame and moved sideway to centre...
    And.....your point is.....what exactly?

    Does that black strip on the window frame in the 4th photo come out? If it does, does it allow the window frame to be moved into the void where the strip was, allowing the complete window to be removed?
    No experience with this type myself, but by looking at the photos it might be a chance?
    Removing this strip might expose how the window is held to the spiral balance or is it connected at the bottom?
    Try to remove the glass reasonably intact so you can measure the dimensions exactly so when you get a piece cut it will fit properly.
    Some photos with the window open might help??
    Never argue with idiots, they will drag you down to their level and beat you with experience.

    Huge thanks to the replies.
    I managed to pull the rubber strip and rest of the broken glass out.
    A few pictures showing the strip.
    Basically, the glass appears to go behind the aluminium frame by 5mm. I've attached a picture that shows two lines, the exposed rubber lip that is visible when glass pane inserted and there's a second line that shows where the glass sits behind the frame.
    So, the "window" part would be 58cm high by 92.5cm wide. However, since the glass extends into the frame, the glass pane would be something like 58.5cm x 92.5cm
    Because the glass pane is obviously bigger than the outside/visible frame, I'm not sure how it would slot in? As it is roughly .5cm bigger on all sides.
    I can't see how the frame would pull apart. I thought the top may come off and hit it a few times with a rubber hammer, but no go.

    Yes, I think so. You might be onto something. That is some kind of "spring" to keep the window open when it is slid up. I'll give it a shot.

    With the shape of the rubber strip being a U shape that goes around the glass then the sash will need to come out. The full frame stays in the window opening.
    The sash frame needs to be disassembled so it can be reassembled around the glass with the rubber installed on the edge of the glass.

    I think Whitey is onto the likely method to remove the sash.
