What it’s Made From

made from icon.jpg

Alumina (Al2O3): Provides high-temperature resistance and stability.

Silica (SiO2): Ensures structural integrity at high temperatures.

Clay: Acts as a binder and provides plasticity during the manufacturing process.

Additives: May include materials like zirconia to enhance specific properties such as thermal shock resistance.


variations icon_edited.jpg

High-Alumina Fire Brick

Description: Contains a higher percentage of alumina, providing superior temperature resistance.

Applications: Suitable for areas exposed to extremely high temperatures, such as industrial kilns and furnaces.

Insulating Fire Brick

Description: Lightweight with low thermal conductivity, offering excellent insulation.

Applications: Ideal for lining kilns, forges, and other high-temperature industrial equipment.

Magnesite Fire Brick

Description: Made from magnesia, known for its high thermal resistance and stability.

Applications: Used in environments requiring high resistance to chemical corrosion and thermal cycling.

Tools Required:

Trowel | Mixing bucket | Spirit level | Brick saw | Protective gloves Fire bricks | Refractory mortar | Water

Materials Required:

Step-by-Step Guide:

  1. Preparation: Ensure the base is clean and level. Measure and mark the layout for the fire bricks.

  2. Mix Mortar: Prepare the refractory mortar as per the manufacturer's instructions.

  3. Lay Bricks: Apply a layer of mortar and place the first fire brick, ensuring it is level and aligned.

  4. Build Up: Continue laying bricks with mortar in between, maintaining consistent joints.

  5. Cut Bricks: Use a brick saw to cut bricks to fit as needed, ensuring tight joints and a secure fit.

  6. Check Level: Regularly check the alignment and level of the bricks as you build up the structure.

  7. Curing: Allow the mortar to cure properly before exposing the fire bricks to high temperatures.

Technical Specification

Single Units

Ideal for small projects, repairs, or when only a few bricks are needed.


Typically sold in bulk, with each pallet containing around 300 to 500 bricks. This option is suitable for medium to large construction projects.


Smaller quantities than pallets, often sold in bundles of 10, 20, or 50 bricks, suitable for minor projects or additions.

Environmental Impact
