Insulating Bricks

Insulating bricks, also known as fire brick, refractory brick, or IFB, are a kind of highly efficient, energy saving, low-carbon, environmental protection advanced products which are manufactured according to ASTM standard. WAM series products are the best lining and insulation materials in all types of industrial furnaces in the field of Metallurgy, Aluminum, Petrochemical, Ceramics, Power and Glass. They can be applied as heat insulation or no-melt erosion parts of the working layer.The products have been widely used in the various furnaces and achieved satisfactory results.

Advantages

Low Thermal Conductivity

More porosity brings excellent insulation effect,energy saving.

High Crushing Strength

High crushing strength under thermal state, volume stability.

Low Heat Storage

Little thermal storage when absorb more heat, energy saving effect is obvious.

High Purity

Low content of iron, alkaline and metal impurities.

Accurate Dimension

Precise brick size by machining, cutting and grinding special shapes, expediting bricklaying.

Customized

No longer are there design limitations caused by traditional standard brick shapes and sizes. The nominal cost of customized sizes is more than offset by the elimination of many mortar joints and significant labor savings.
