BNZ Materials manufactures, and is a
worldwide supplier of a range of specialty
industrial insulations and refractories for
petrochemical, electrical, aluminum, steel,
ovens, glass, furnace, ceramics, fire
protection and other industries.
BNZ produces thirteen types of
Insulating Fire Brick (IFB) for use in
applications from 2,000°F (1,093°C) to
3,200°F (1,760°C). Each type is formulated
to meet specific thermal and physical
requirements and after firing is machined to
precise tolerances.
Made from high purity refractory clays and
other ceramic raw materials, these IFB
contain a carefully graded organic filler
which is burned out during manufacture to
give a uniform controlled pore structure.

Advantages
High Insulating Value
The light weight and high insulating value of BNZ IFB make possible thinner furnace walls, improved efficiency and lower operating costs.
Strong
The high compressive strength of IFB allows for self-supporting structures at elevated temperatures. IFB are compatible with dense fire brick and add strength to the whole construction.
Low Heat Storage
Lower heat storage versus dense brick means reduced fuel costs in cyclically operated heating equipment.
High Purity
BNZ IFB are low in impurities such as iron which can adversely affect refractory performance in many applications. They are used in many furnaces operating with a controlled atmosphere.
Accurate Dimensions
Because BNZ Insulating Fire Brick are machined to precise dimensions, courses can be laid quickly and easily. The result is a stronger, tighter refractory lining resulting in less heat loss through the joints.
Typical
Applications
Recommended
for
use
as
primary
hot
face
refractory
linings
or
as
back-up
insulation
behind
other
refractories
in
furnaces,
flues,
kilns
and
similar
high
temperature
industrial
equipment.
Size
is
no
obstacle.
Most
BNZ
IFB
are
available
in
Zelie
Jumbo™
series,
which
require
no
mortar
joints
to
produce
sizes
up
to
24"x9"x3".
No
longer
are
there
design
limitations
caused
by
traditional
standard
brick
shapes
and
sizes.
The
nominal
cost
of
Zelie
Jumbo™
sizes
is
more
than
offset
by
the
elimination
of
many
mortar
joints
and
significant
labor
savings.

Temperature
use
limits
should
be
considered
along
with
other
properties
of
the
IFB
in
determining
the
proper
grade
to
use
for
your
application.
The
hot
load
deformation
along
with
the
mean
temperature
(i.e.
the
temperature
at
the
midpoint
of
the
brick)
should
be
considered
as
well,
to
assure
a
successful
application.
Guidelines for the mean temperature of each type brick are:
Consult

recommendations
on
the
best
combination
of
products
for
your
temperature,
processing
and
atmospheric
conditions.
Available
Forms
In
addition
to
the
great
number
of
standard
sizes
available,
Insulating
Fire
Brick
are
also
available
in
special
cemented
or
machined
shapes.
A
large
machine
shop
at
the
factory
is
capable
of
supplying
accurate
machined
shapes
of
nearly
any
description.
The
unique
large
slab
means
that
a
finished
shape
will
have
fewer
joints
than
shapes
made
from
any
other
IFB
manufacturer.
IFB
shapes
with
drilled
holes,
grooves,
flycuts,
tapers,
radii
cuts,
skew
planes,
tongue
and
groove,
notches
and
chord
cuts
are
easily
fabricated
in
any
quality
IFB.
