Kiln Building Refractory Bricks and Insulating Firebrick for Furnace Building and Repair.
Soft bricks and hard bricks are made of refractory fire clay, ground-up pre-fired
clay aka grog, and alumina .
Refractory fire bricks are fired to a very a high temperature in massive industrial furnaces.
The soft bricks are very light and porous and are designed to
insulate.
These kiln fire bricks are used in electric and gas fired kilns and as an outer insulation in wood and salt kilns.
The dense / hard bricks are very heavy and are designed as structural
bricks and are employed in kilns and furnaces that have caustic or abrasive environments such as in wood burning kilns, salt kilns and coal fired
furnaces.
Refractory
shapes include precast cement and fused or sintered refractory products
that are formed prior to installation in furnaces, boilers or other
high temperature equipment. Refractories
are hard, heat resistant materials and products such as alumina,
silicon carbide, fire clay, bricks, precast shapes, cement or
monolithics and ceramic kiln furniture. Ceramics and refractories have
high melting points are suitable for applications requiring wear
resistance, high temperature strength, electrical or thermal insulation
or other specialized characteristics.
Kiln building refractory fire bricks, blocks, and tiles are stacked to form insulating furnaces, boilers or other thermal process vessel walls. The refractory fire bricks are usually cemented together with refractory mortar.
Please note:
BRICKS SHIPPED UPS GROUND CARRY A $0.75 /BRICK PACKING FEE AND A $5.00 MINIMUM PACKING FEE.
- Bricks carry a $0.75 per brick double box safe packing fee when going UPS.
- There is a $5.00 minimum on this packing fee.
- ie. 1-6 bricks carry a flat $5.00 packing fee. Add $0.75 per brick for 7+ bricks.
- NOTE: This does not apply to large quantities of bricks which ship palletized via our truck or common carrier.

INSULATING BRICKS/SOFT BRICKS
CHOOSE SOFT BRICKS FOR INDOOR OR WELL COVERED AREAS : Used in Gas and electric Kilns
2 1/2” and 3" Series: STRAIGHTS , WEDGES AND ARCHES
G20 = 2000 degrees F
G23 = 2300 degrees F
G26 = 2600 degrees F
G28 = 2800 degrees F
Note: Soft bricks can be cut with a regular carpenter's hand saw to create custom shapes.
HARD BRICKS
CHOOSE HARD BRICKS FOR OUTDOOR APPLICATIONS : Used for wood burning kilns. Soda kilns generally require 70% alumina hard fire bricks.
HIGH HEAT DUTY -Economical high-duty refractory fire bricks will go to cone 31-32. Suitable for backup
linings, and other areas that encounter moderate operating
temperatures. Not suggested for abrasive conditions. (equivalent to
Empire) 2 1/2” except where * (3”)
SUPER DUTY -Exhibits high
strengths and low shrinkage, good resistance to thermal shocks. Can be
used as the inside lining of kiln. Recommended for blast furnace
stoves, open hearth and coke oven checkers, glass tanks and anywhere a
high density, low porosity super duty brick is desired. Will go to cone
33-34. (equivalent
to Clipper) 2 1/2” except where * (3”)
70% ALUMINA -A chemical and
ceramic bonded 70% alumina brick designed for the following
applications: Electric furnace roofs, ladle bottoms, side walls and
slag lines, rotary kilns, cement kilns, torpedo ladles, tundishes, and
hot zones of lime kilns.
