How can I find replacement windows?

[color=#000000]Hi guys,[/color] [color=#000000]Hope you are having a productive quarantine and making good use of your time at home. I had some time on my hands last night so I took the initiative to create something that needs to be fixed (see photos).[/color] [color=#000000]Can anyone chime in with a clever way to fix the door without having to buy a new one?[/color] [color=#000000]I promise my next post will be about a more productive project.[/color] [color=#000000]Peter[/color]

I made an indoor rosemary garden behind my bedroom window and placed my stairclimber exerciser behind the plants. Sunshine is going through the window and shines on the plants and on my torso when I exercise. Google search shows that UV rays may not be penetrating the window- making my efforts useless. No UV to the rosemary and to my torso. I have read Oberon's (still a member?) replies here but I would like to be informed more. I placed a lighted candle on the window at night and saw two very clear images of the candle and the flame of the candle. But I also saw a very faint (almost invisible) image of the flame of the candle (not the candle) at the back of the two very clear images. Is the very faint image of the flame the third image that Oberon was discussing? Are there other ways to know if the window is blocking UV? I want the UV in. Thank you in advance.
