[Superman]

I have a house, made of brick (roman brick?), which has original 1953 single-paned windows. Very few of them can be opened for ventilation. I would like to replace them. I have measured them, but my inclination is to have a professional do the work, including the measuring and ordering. I suspect that custom-sized windows much be used, rather than off-the-shelf windows. Correct? I also suspect that windows can be fabricated which are a more subdued color compared to most brilliant white vinyl windows. If so, this would work better for aesthetics.

School me on brick house window replacement.
