You don't say what your kiln is made of, hard brick or insulation brick. =
I once did an outside insulation of 1/2" rigidized fiber board sheets =
over a G-23 insulation brick Minn. flat top kiln by using fender washers =
and 1 1/2 inch garden variety pan head screws, directly into the =
insulation brick, about 1 1/2 feet apart all over the fiber board. It =
worked fine. I probably should have used stainless screws, but these =
held for 10 or 12 years, until I rebuilt the kiln. It was already a =
number of years old before I did the exterior insulation. I also should =
have sealed the fiber after applying, but didn't know any better at the =
time.

Hard brick would be another matter. I would probably use welded or =
screwed(into the kiln frame) external metal straps to hold the fiber =
board in place.

Can anyone reccomend a way to line the outside of a kiln with ceramic fiber
boar (inch and a half thick). I got a good deal on several dozen pieces and
i want to use it for the insulation value (1900 degree rating) and this
seems like the best place to use it. But i am not sure whether to try to
mortar it in place or to try to fit in into the angle iron framework, and
then add some additional metal pieces along the sides to fasten it. Any
input would be appreciated. thanks!

When I built my fiber kiln, the fiber board was 2300 F and it was the
surface touching the flame. Underneath I had fiber and then mineral wool. My
recollection is that fiber board is not waterproof so dont use it where it
will be exposed to weather. Try facing the outside with heavy duty
aluminum foil and fit them in the frame. Line the inside with fiber and
maybe then a layer of board toward the flame. That should give you a tight
kiln body.

Good Luck

Donald who now fires a soft brick kiln with little or no maintenaince.
