My 1800s farmhouse has an enclosed porch that I am remodeling
I have: 1) removed all the crown molding; 2) pulled down the fiberboard ceiling; 3) removed a layer of roofing paper (that was conveniently holding the moisture from 2nd story bathroom against the tongue and groove ceiling); 4) removed the T&G 'porch' ceiling; 5) removed old 'rock wool' insulation; and 6) removed the abjectly
frightening K&T wiring.
I am now contemplating insulating the space before I re-wire and put up drywall ceiling.
Here are my parameters (I seem to like lists today, so I'll stick with it): 1) this is an attached porch with no venting - and I am not planning on venting (I am loath to cut a hole in a roof that is not leaking) on the bright side there is no evidence of any moisture issues where it was insulated; 2) It is heated (reiker ceiling fan handles the room nicely!); 3) The underside of the roof is not
plywood - it is a mix of solid boards and battens; and 4) it is over a finished-ish basement that gets some heat, but it never gets very warm under there AND it currently has some un-remediated moisture problems (I know, I know, but it's got to wait).
I live on the eastern shore of maryland: HOT, HOT, HOT in the summer (though the porch is shaded 90% of the day), enough cold days and nights that I need it to be warmer, and some below freezing nights in the winter.
Here are my questions:
1) Do I insulate under the floor? What should I use? Can I just staple bats between the basement joists?
2) What do I use to insulate the roof?
3) What's all this about vapor barriers - they seem to cause as much problems as they fix?
4) Can I also insulate the new ceiling?
Wow - thanks for reading all this mess - I would appreciate any thoughts, horror stories, cautions, and advice.
