I have an old farmhouse. In the 70s, the previous owner redid a room adding
insulation, rough pine-board wainscoating and then sheetrock on the top 1/2.
I'm ripping out the dark stained (and scratchy---daughter scrapes herself
all the time) pine and installing douglas fir beadboard.

Question: the beadboard is thinner than the barn board so I have to add
furring stripes or something to make it matche the sheetrock face (no
sheetrock where barn board was). Instead, I was going to beef up the
insulation---adding fanfold house sheathing (blue dow), then the waincoating
back on top. This is normally used outside, but I've seen it used in
basements. Any worries here?

Thanks.

tell your friends it was supossed to go only on the OUTSIDE of the
basement if it's this product at:

so, what flat foam insulation is rated for interior use?

the worldwide web has many answers for you but your question is best
answered by your local building code, easiest by the building inspector
in your area. in a tropical climate or where mold is going to be a
problem there is a foam concrete for example installed by an insulation
company. the temperature at which various foams can be installed may be
found in their specifications, often requiring 40 degrees F. or
warmer. it's winter here right now in buffalo ny but you may have just
the climate for this stuff today which doesn't burn.
in your town they may want fiberglass batts covered by fire rated
drywall or concrete board. if your farmhouse is plank construction,
insulation cavities may be missing. if they are present i would look to
some do-it-yourself foam canned insulation.

Most are. Styrofoam and expanded bead board is and they are made with fire
retardant in them. By code though, they must be covered with sheetrock as
they can burn if there is something to feed them with fire, otherwise, it
will go out.

I'd recommend using homasote or some other fire-treated insulating
panel-board instead of foam, unless the wainstcoating is fire-rated or
at least 3/4" thick. But I also wouldn't stress about the
difference.
