Jeremy -
I think you are on the right track, and this should work fine, but I have a
few suggestions. I would install just a single layer of wallboard spaced
out from the chipboard wall, in order to leave an airspace between the two
surfacesl. Leave a space at the bottom and the top. In other words, have
the wallboard start a few inches off the floor, and have it stop a few
inches below the ceiling. Get some plastic 1/2" i.d. hot water pipe, and
cut a big supply of 1" lengths, and use those for spacers everywhere you
drive in a drywall screw into a stud to attach the wallboard. As soon as
any radiant heat from the kiln penetrates the wallboard, convection will
cause cool air to enter the bottom of the space while the warm air exits the
top of the space, preventing the chipboard wall from ever getting too hot.
I have used this system, and it works very well.

I would permanently install a good exhaust fan in the wall, with a wall
switch, but also a thermostatic switch wired parallel in the circuit, so
that the fan goes on automatically whenever the room temperature gets above
100 degrees or so, whether or not the wall switch is turned on. That will
safeguard you in case you forget to turn on the fan. I wouldn't want to
rely on things like an open door and an open window, because some
"well-meaning" individual could always come along and close the door and/or
window. Don't allow for that possibility.
Good luck -

OK, I'm shoe-horning a studio into too small a space, I got that.

That said, I'd appreciate some feedback on plans for a "kiln room".

My 1971 suburbs-on-steriods "raised rambler" in Northern Virginia has a 5'4"
x 7'3" storage space attached to the outside of the house and tucked under a
second floor enclosed deck ("Florida room"). One 7' wall is brick (the
outside skin of the house itself), the other is studs and particle board
with a window in it. One 5' wall has the door in it opposite another stud
and particle board wall.

I hope to put a Skutt 818 electric kiln in this space.
I'm concerned for safety and intend to...

1) put a double layer of wallboard over the exposed stud/chipboard walls
2) keep the door and window in the room open when firing
3) put a box fan in the open window to exhaust air
from the room to the outside.

What do the more experienced shoehorners on clayart have to say about the
relative safety of this plan?

Peace!
