I have a old house that was built in 1933 and the previous owner installed cheap windows. I want to replace the windows with aluminum ones. The current windows are 28" by 60", but they are installed where the old wood frame screens would of been. If you look behind the windows, on the inside, you can see the grooves where the old counterweights were located. If you measure where these old grooves are the window height opening is not 60" it is 58".
My question is should I order windows that are 28 by 60 or 28 by 58???
Thanks for your help
