shop and wall safety for kiln

Bruce, I have been reading some of the posts for your question. I have a very small work shop and would like to share what I have done. My kiln sets very close to the walls and even right next to one of my wooden work tables. I mounted cement board, like you use in bathrooms in the shower or tub stall. They do not heat up. I even leaned one against the end of the work table with no mounting and works great. Hope this helps.

Hi Bruce,

Don't do two layers of dry-wall, it will accomplish nothing but to eat money
and time.

Instead, appreciate that you need to establish practicaly, how far from a
wall your kiln needs to be or can be, and to determine then if you even need
anything at all to deter the heat from effecting the wall.

If the kiln needs to be close enough to the wall for the wall to get hot if
unprotected, then, hang a sheet of sheet metal several inches from the wall,
and if you like, have a fan also which will suppliment the convection of the
rise of the warm Air between the sheet metal and the wall...

Two layers of dry wall will not help anything except to slow an actual fire.

The paper and whatever paint that is on the outside of the dry-wall, once
hot enough, burn anyway, or blister and burn or as may

Figure out how far from the wall your kiln can be without being a problem,
do an experimental run to see how hot hot may be for the wall with that
distance, and go from there. If you can keep your hand on the wall during a
sustained fireing, then there is nothing to worry about...if not, then at
least have as much distance as possible for the layout, and hang the

Too, you could probably insulate the outside of your electric Kiln with
Kaowool or similar, and then not only make it more effecient, but also let
you get it closer to a wall without so much heat comeing off of it to effect
that wall.

Good luck...!
