I have something like this: https://www.homedepot.com/p/Clearly-Secure-31-in-x-23-25-in-x-3-125-in-Frameless-Wave-Pattern-Vented-Glass-Block-Window-V3224DC/203608892

My version opens by turning a nob, and there’s a screen over it. (Not the glass blocks obviously, just the little window in the center). The screen is letting in LOTS of cold air, and my other windows don’t have a screen, but rather an additional pane of glass/plastic. I’d like to get one for my screened window, but I cannot for the life of me find it or even what it is called.

Any help is appreciated, thank you in advance.
