Marshall: Compressing fiber is a good idea when veneering or retrofitting
a kiln! A baffed and spalled IFB kiln covered with 1 inch compressed
Fiberfax sprayed with ITC 100 has one hell of alot more R value than the
initial kiln.
When you make blanket statements about what is good and what is not good, please
do your homework. I am sure you would insist this of your elementary
school phys. ed class.
As a matter of fact, some fiber is sold in a compressed form. The fiber
board is vacuum molded from the basic fibers into ridgit boards. A half
inch up to one and a half inch thickness has much greater insulation than
brick of the same thickness. Compression also helps with linear shrinkage
when I apply the squares of fiber. Many companies sell fiber modules that
are compressed by as much as 33%.
For your homework assignment I am suggesting you read a book. Take the
night off from Clayart and get a hold of "The Energy Efficient Potter" by
Regis C Brodie publisher Watson Guptill. I bought the book in 1982 and it
describes veneering and compressing fiber in a very complete chapter.
According to Brodie a one inch compressed wallpaper veneer job will reduce
your fuel consumption by 8%. 2" of fiber and savings are 20%.
As I used to say to my class! " If you do come to class without your
homework done, just don't try to BS me that you have!"
Cheers,
Tony

AGAIN do an insulation TEST (see my prior msg) comparing a 1" thick
insulating fiber blanket which is not compressed to the SAME fiber blanket
material which is then compressed to 1/2" or whatever and then has the
refractory coating applied. If the test is properly conducted then the
data will tell the facts. I will be waiting to hear the results from these
two tests I just prescribed. ...Marshall

You may have missread the first message on compressing fiber to "veneer" the
inside of a kiln that is in bad shape, using ITC 100 as the glueing agent.
After the fiber is glued on than the whole interior is sprayed with ITC 100.
It really has nothing to do with R factors of fiber but just a convenient way
to cover bricks and cracks in a badly deteriorated kiln.
