Cold Face Insulation Bricks (CFI)

Product Description

Cold face insulation bricks, also known as insulation fire bricks or insulating refractory bricks, are used in applications where the primary need is for insulation rather than load-bearing or resistance to extreme heat. These bricks are lightweight and have a high porosity, providing excellent thermal insulation. They are used in backup lining behind Hot face lining. Here are some key characteristics and uses of cold face insulation bricks:

Characteristics:

=============================

Low Thermal Conductivity:

These bricks have low thermal conductivity, making them effective insulators, reducing heat loss and conserving energy.

Lightweight:

Due to their porous structure, they are much lighter than standard fire bricks or other refractory bricks, making them easier to handle and install.

High Porosity:

The high porosity contributes to their insulating properties and also reduces the density of the bricks.

Low Density:

The low density of these bricks contributes to their lightweight nature and ease of installation.

Moderate Temperature Resistance:

While they can withstand high temperatures, they are not designed for direct contact with the highest temperature zones in furnaces or kilns. They are typically used in the outer layer of insulation.
