Please someone answer, I am very hot! I went to my local home improvement store today and they sold me a "conversion kit" that is not suitable for this type of window, even though I described in detail what I am working with.
I have a window that slides to the left to open. I live in a large brick apartment complex. I have a regular window air conditioner, but I need something to fill in the top space to secure the A/C and not let any of the outside air in.
