I am contemplating buying a house with a screened in back porch I want
to close off for an office and music room. My wife wants to replace the
screens with windows. That will leave me with mostly windows on three
sides and Hardiplank, a cement based exterior clapboard siding, on the
fourth.

What kind of problems am I going to have? My current room is
double-layered 5/8" wall board on 12" studs. It is pretty solid. It is
also tapered to reduce any standing wave problems. This room is all new
to me and I'm not sure what I am getting into.
