How do you construct a 1-hour ceiling/floor assembly?
I have found assemblies to use, but I can't figure out how to install doors and windows in the wall.
To be specific... I am designing a duplex with one unit upstairs, and the other unit down. So instead of a fire wall (easy to do) I have to do a floor/ceiling assembly. Since the sheetrock on the underside of the assembly has to be continuous, the walls holding up the floor also have to have a 1-hour fire rating.
The problem is... I need to install doors and windows in the exterior walls.
How can I do that, while maintaining the fire rating? The owners don't want windows and doors with metal wiring in the glass.
I see apartments all the time with regular doors and windows, so I know THOSE structures meet fire code. How are they accomplishing this?
Thanks!
I am a Certified Professional Building Designer... I have been drawing home plans (and duplexes) for 17 years. I have a stamp for all my projects. I have asked three architects that I often work with about this, and they do not know the answer.
To "Not as think..." I obviously was not addressing you on this question. I was actually hoping for an architect or designer to weigh in, but no luck. I know this whole thing is fairly simple, but none of the trade professionals I work with have ever done an over/under design for a duplex (especially without a sprinkler system).
Thanks again,

you should hire an architect to help, its very obvious you haven't done this before
you will need stamped drawings for the building permit anyway so you may as well save yourself the aggravation and bring in an experienced professional sooner rather than later
I would suggest some soundproofing be added to that ceiling/floor assembly too
