kiln bricks for home insulation? a little bit ot. . .

updated mon 5 jul 04

 

George Byron Koch on sun 4 jul 04


I'm impressed by the way the outside of my kiln is relatively cool, even
when it is 2000 degress F inside, and also how long it stays hot inside,
while it is cooling down. It seems like the kiln bricks would make good
insulation for a home if placed in the outer walls instead of fiberglass
insulation.

Does anybody know if this actually makes sense or has been done? Or what the
R value of a kiln brick is? We may build a house in the next 2-3 years, and
I'm trying to make it as energy efficient as possible. Any and all ideas
welcomed.

THANKS!

Considering the price of (even) used kiln brick,
I would suggest that you use 2X6 or 2X8 walls
stuffed with insulation, instead of using kiln brick.
You can specify these types of walls to your
builder or architect as a specification prior to his/her
giving you a price for construction. Do not let
them tell you that "with the new insulations, 2X4
is just as good". Ain't so. Go find a builder willing
to work with you.

The reason that insulation works is that it traps air,
and creates an barrier or gap between inside and
outside air. The more (thicker) the air layer trapped,
the more effective that barrier will be.

The only place I can see that a kiln brick might be
effective as insulation (since they serve to insulate
from HEAT) would be on the roof, and then only in
direct sunlight in the high sun of summer. Since soft
brick is so easily eroded, it would not be a good
choice for a roofing material...unless you plan to
raku on your roof which is also not a good idea.

If you have access to that quantity of kiln brick, build a kiln,
take the money you make from the pots you create and fire
in that kiln, and pay for the extra thickness in the walls.
