Hello folks=21 :)

I am excited at the idea the kiln will be soon passing through my doorway
and have questions popping right and left for which I cannot find an answer
or peace of mind.

I only have one spot in the house to put the kiln, the garage. The walls
are drywalled and insulated -- regular house job. The temperature in there
will still vary greatly from about 90oF to 30oF, perhaps lower, across the
four seasons -- Chicagoland nasty winters.

1. should I line the garage wall with something since the kiln is bound to
be near it and with what? I can probably keep it from 1ft to 2ft away from
it easily to begin with.

2. in the winter, due to the freezing temperature, should I line the kiln
with an extra fiber blanket or something? I will have a vent so covering
the top doesn't seem possible.

Thanks a million. Cheers,

--

PS Thank you for the replies to my material suppliers question. I am
finally ready to tackle the task.

Fabienne,
The manufacturer of my electrics recommends no less than 18" from the
wall. Since I have a safety conscious husband, he bought a 4x8 sheet
of "crete" board, aka concrete board, aka durarock - which is
fireproof and nailed it up behind my first kiln. I think 12" is
pushing the envelope a bit. Those suckers get obscenely (quoting
Vince, who's right as usual) hot. For a short time my clothes dryer
was 12" from the side of the kiln, and when we finally moved it the
white porcelain finish was scorched brown. Can't be too careful.

Hi, Faye,
On the side of your new kiln there should be a tag with the UL logo on
it that will tell you all that stuff about how many amps and kilowatts
your kiln draws, and one of the things on there should be a figure for
how close you can put it to a combustible surface. I think mine says 8
inches. Now, whether they consider drywall (whether hung by pond scum,
with tobacco juice on the back of it, or not) a combustible surface or
not, I'm not sure. But I don't think so.
Hapy firing,

------------------
I suggest you keep the kiln 2 ft from the walls. I believe my kiln said
18=22 were required. Keep the garage door open in the summer and you
should be more comfortable. I wouldn't worry about extra insulation in
the winter. When you are at 1000 degrees inside, what difference does
40 degrees outside make?

My thoughts for what they are worth.

women wear.

Fabienne,

I don't think you'll have a big "wall heat" problem, as long as the wallboard
is a fire-resistant type. You might add a panel or two of the fire-resistant
wallboard (Home Depot has it) to the wall immediately surrounding the kiln,
for extra protection. I'm assuming yours will be an electric kiln.

As far as the blanket to protect from extreme frost--you probably won't need
it, as long as the garage remains dry when the kiln is not in use. Once the
kiln is running, the elements should keep the kiln constantly hot on the
inside.

Best wishes to you!

Hi Fabe,
I'm in Naperville, if you want to stop by and see what I've done.
I have my kiln in an outside shed, but the situation is about the same. I put
DURAROCK(sp?) on the two corner walls (got it at HOME DEPOT in 4' x 4'
sheets). Be sure to set the sheets away from the wall with some type of
spacer to allow air to flow behind. Don't worry about wrapping unless it's a
very drafty location or you feel you're getting uneven firing based on
outside influences. The ambient temperature really doesn't have much (if any)
impact on what's going on inside the kiln.
Good Luck. Hope to meet up with you at the John Glick workshop.

KEEP CENTERED

Penny H, others:
In some jurisdictions the Fire Code allows use a sheet steel
barrier between kiln and a wall containing combustile materials.
Corrugated barn roofing is freely available and often cheap. It should be
held off the wall by metal collars of 3 cm (+/-) made from copper
household water pipe. The sheeting would be 2-3 cm above the floor so air
can circulate between the wall and the sheeting. When this is in place,
the kiln can be located as close as 20 cm to the steel sheet.
However, having said this, I should note that your insurance
company will have the final word since otherwise you may jeopardize your
household fire insurance coverage.

Hi Tom!

It is better not to use metal as a shield, Metal reflects (radiates) heat.
It is better and just as cheap if not cheaper to use "DUROCK" or a similar
product. This is made out of fiberglass and cement and it comes in sheets in
various sizes. This product is readily available at your local hardware
store.

Warm Regards,
