German/European doors with flanges
I traveled in Germany and Austria this past summer. All doors to hotel rooms (assume many others as well) have a flange - roughly 1/4"-5/8" thk and extending beyond the rest of the slab about that much. I am putting in a door to my music studio and have bought a slab and need to build the jamb. I'm considering routing the edge of the door to create the aforementioned flange (to possibly improve sound isolation and just because they are unique, intriguing and German(?)). Anyway, I didn't pay close enough attention to the detail while there. Has anyone ever seen this (in US or abroad) and, more importantly, does anyone have information about the design. If so, I'd love to get a cross section view of the jamb. Are there still door stops or does the flange serve that purpose? Are there special hinge arangements required to make sure the door, and flange, seat properly on the jamb?
