Dimensions of Lightweight Insulation Bricks
The most common standard size for lightweight insulation bricks is 230 x 114 x 65 mm.
Universal sizes refer to those that can be used in conjunction with other dimensions of lightweight insulation bricks to complete the construction of the kiln’s insulation layer. The following are some common specifications for lightweight insulation bricks, including wedge-shaped bricks. The dimensions of universal insulation bricks facilitate the construction of industrial kilns, allowing for a more compact lining when combined appropriately.
1. When selecting the dimensions of lightweight insulation bricks, it is advisable to choose based on commonly used sizes in conjunction with the structural requirements of the specific areas within the kiln.

Advantages of Lightweight Insulating Fire Bricks
- Fuel Consumption Savings: Using lightweight insulating bricks with low thermal conductivity and small heat capacity as structural materials for furnaces can significantly reduce fuel consumption.
- Increased Production Efficiency: The ability of kilns to heat up and cool down quickly enhances equipment production efficiency.
- Optimized Furnace Structure: These bricks reduce the weight of the furnace body and simplify its construction.
- Improved Environment: They help lower ambient temperatures, enhancing working conditions.
- Extended Equipment Lifespan: Their resistance to high temperatures and acid-alkali corrosion reduces the frequency of kiln maintenance.
- Reduced Installation and Transportation Costs: Their lightweight nature contributes to lower costs in both installation and transportation.
- Precise Dimensions: Products from Kerui are manufactured with accurate dimensions, facilitating quick and easy installation, which improves construction efficiency.
