I would like to replace my current, old, double hung arched windows. They are in a solid 3 course brick house. Considering casement instead of double hungs for replacement. Would casements work? I would like to get rid of wooden sills and let new window frames sit the on masonry. Is this possible?

What about trim on the inside? Currently have nice trim on the interior of the house around each window. However, since solid brick walls I don't need the trim if I replace with window that fills opening. Right? Not sure how to proceed.

Any input on double hung arched versus casement arched versus rectangular window with arched window above appreciated. Current window is approx. 68" high by 30" wide, these measurements of window sash not rough opening. TIA.

 

Replacing or retrofitting windows in ANY masonary wall is, or can be, challenging. If you've never replaced or retrofitted windows before, I would discourage you from letting these be your first.

You are probably looking at needing 2 windows per opening. I've never seen a casement window with an arched top. Don't know if they exist. So, a rectangular casement, and an arched transom window above it. Best check with a local glass shop and see what you can get before you do anything.
