Insulating Fire Bricks
Durabrick® IFB 23
DURABRICK® IFB 23 is a lightweight insulating firebrick classified to 2300°F, offering high dimensional accuracy, low dusting, low heat storage and good strength for its density. It may be used as hot-face or backup insulation within its classification temperature and compatible furnace atmosphere.
Durabrick® IFB23 HS
DURABRICK® IFB23 HS is a high-strength insulating firebrick designed for applications where greater structural strength is required than conventional lightweight IFB. Its higher-density structure combines effective thermal insulation with enhanced load-bearing capability and mechanical durability.
Durabrick® IFB 26
DURABRICK® IFB 26 insulating firebrick offers an excellent balance of thermal efficiency, structural integrity and dimensional stability. It provides reliable insulation while retaining the mechanical strength needed for hot-face and backup linings exposed to repeated heating and cooling cycles.
Durabrick® IFB26 HS
DURABRICK® IFB26 HS is a high-strength insulating firebrick engineered for mechanically demanding high-temperature linings. Its higher-density structure combines effective insulation with enhanced load-bearing strength and durability and enhanced resistance to breakage while retaining effective thermal insulation.
Durabrick® IFB 28
DURABRICK® IFB 28 is an insulating firebrick providing low heat storage and good compressive strength for high-temperature insulation service. Suitable where the lining must also withstand high thermal shock and mechanical loads at elevated temperatures.
Durabrick® IFB 30
DURABRICK® IFB 30 is an insulating firebrick classified to 3000°F for high-temperature insulation service where low heat storage and refractory stability are required. It combines low lining mass and heat storage with strong structural performance.
Features:
- No burnout material- Hot Face Insulation
- More light & More energy efficient
- Low reheating linear change
- High strength
- High Dimensional Accuracy
Our Range:
Durabrick® IFB 23, 23 HS, 26, 26 HS, 28, 30, 32
Durabrick® IFB 23F
DURABRICK® IFB 23F is a foam cast, low density lightweight insulating firebrick focused on thermal efficiency, low heat storage and rapid thermal response. Its uniform pore structure helps reduce lining heat loss and supports faster heat-up and cool-down while maintaining practical structural integrity for furnace insulation.
“Upto 30% lower density”
“Ultra Low thermal conductivity”
Our Range:
- Durabrick® IFB 23ES,
- Durabrick® IFB 26ES
Durabrick® BA 90
DURABRICK® BA 90 is a bubble-alumina insulating brick. Its lightweight refractory structure reduces stored heat while providing excellent dimensional stability, thermal-shock resistance and chemical durability where both insulation and strength are required.
Durabrick® BA 99
DURABRICK® BA 99 is an ultra-high-purity bubble-alumina insulating brick for extreme-temperature service where low lining mass and dimensional stability are critical. Its lightweight refractory structure minimizes stored heat while resisting corrosive atmospheres and contamination in demanding high-purity thermal systems.
Specifications:
- Material Composition: High purity bubble alumina
- Additives: High property micro powder
- Shaping Method: Vibration press
- Sintering Temperature: Over 1700°C
- Classification Standard: ASTM C155
Our Range:
- Durabrick® BA 90
- Durabrick® BA 99
Hot Face Kyanite (HFK) insulation bricks are widely used, cost effective bricks which are primarily used as the working face in furnaces, kilns, and other high-temperature processing equipment.
Features:
- High Temperature Resistance:
- Withstand temperatures up to 1,260°C (2,300°F)
- Low Thermal Conductivity: Improving energy efficiency in high-temperature applications.
- Kyanite provides High Strength and Durability
- HFK bricks are resistant to thermal shock, mechanical wear, and chemical attack.
- Lightweight Despite their strength
Our Range:
- HFK 140
- HFK 150
We also offer high performance diatomite & molar insulation bricks on request. These bricks are used for specialized applications with high strength and low density.
• High strength,
• Low heat capacity
• Low thermal expansion
Their thermal shock resistance is high due to low thermal expansion and contraction factors. They have low permeability against gases and resistance to weak acids. These insulation bricks are used as back-up insulation in the industrial furnaces.

Features
Know More About
The Product
Low Reheat Change:
Low PLC results assured safety in application and long life span.
Low Thermal Conductivity:
Good thermal insulation makes thinner furnace walls possible, improving efficiency & lower operation cost, making a contribution to environmental protection.
Low Density & Low Heat Storage:
Due to lightweight and low thermal conductivity, bricks absorb less heat inward, which means reduced fuel cost and fast heating up in cyclical operation heating equipment.
High Purity:
Low in impurity like Iron & alkali flux content to realize refractory performance in specified atmosphere.
