Hi everyone. I am replacing 2 windows in my dining room. The windows are
side by side, but operate separately (each are opened separately, have their
own screens, etc.), but here is my question. Are these windows that are
side by side 2 single windows purchased separately, but mounted side by
side, or do the 2 windows come as one whole unit (piece) already placed and
attached side by side when purchased from the store?
Thanks
Eric
