What if the broken bridge aluminum window can't be opened? The broken bridge aluminum window is stuck and can't be opened.

If your broken aluminum window is stuck and can't be opened, you can try the following methods to solve this problem:

Use lubricant: You can spray some lubricant around the aluminum frame of the window, which can help the window to open more easily.

Tap the aluminum frame with a wooden stick or handle: this will help the window get rid of the stuck state and open it more easily.

Soak the aluminum frame with hot water: you can pour some hot water around the window and let it soak for a while, which will help soften the ice around the aluminum frame and make the window easier to open.

Tap the aluminum frame with a hammer: If all the above methods don't work, try tapping the aluminum frame with a hammer to help relieve the stuck state.

If none of the above methods can solve your problem, or if you have any questions about how to solve the problem of sticking broken aluminum windows, I suggest you consult a professional or contact the window manufacturer.
