I am replacing a window in a garage. I measured the rough openings but the current window in the garage is quite old and I am not even sure what kind of window it is (or the proper terminology for this kind of window).
I want to put a 'normal' double hung replacement in the garage, but I am curious if there are any special precautions when replace a window of this type.
Here are some images of the window:
When I measure the rough opening I noticed that the window had a metal frame that a was a little bit wider than the rough opening, which made me think that perhaps this would cause some issue during replacement.
Pardon the appearance of the garage; it was not well maintained and I am trying to fix that.
