Welcome! and congrats on your Sunny.
Is there a chance you can post a picture of the window, and the size of it and where you measured it?
I'm trying to visualize which window could have the screen blow out, unless maybe it is an emergency exit window that the entire large glass pain tilts out. Those screens come out easy so you can climb of of them, so they may bounce off and out.
To attach a pic, see this post I sent to another member recently it tell how to do this.https://www.sunlineclub.com/forums/f...tml#post152681
Once we know which one you are looking for, there may be some options that are cheaper then $300. The original window manufacturer is still in business. When we see the window can can tell what you have.
Hope this helps
