Operable transom windows for interior use?
I'm building a "new old-house" and want to put transom windows above eight of the interior doors for improved air-circulation and to bring in more natural light into a couple of hallways. Seems like the only transom windows now available are "fixed" windows for exterior use. That is, they are invariably vinyl or aluminum clad and typically double- or triple-glazed. I don't need multiple glazings for interior use and sure don't want or need the aluminum or vinyl cladding! I'm just looking for simple single-glazed wood-framed windows that opens on a hinge at top or bottom... like I remember being in my Grandmother's house fifty years ago!
I really prefer the kind that are hinged at the bottom and open at the top (I think they're sometimes called "hopper" windows) but will be happy to find either so I don't have to spend and arm and a leg having something custom made. The windows are all going over standard 32" wide doors and I can go with transoms that are anywhere from 9" to 18" high. (Will select the door height based on the transoms I find.)
I've already searched through the antique shops in my area (central Texas) and haven't been able to find one that would fit - much less eight windows so would very much appreciate any advice anyone can offer.
