High Strength Insulation Brick

High Strength Insulation Brick： HS-INS Brick is made by replacing part of the heavy-duty aggregates with microporous lightweight aggregates during the production process.
Traditional dense refractory bricks have high density but almost no insulation effect; Traditional lightweight insulation materials have good insulation effect but low strength.

HS-INS Brick combines the high strength of dense refractories with the low thermal conductivity of lightweight insulation materials. This product is suitable for insulating the inner walls of high-temperature kilns. It can be used directly in the kiln lining process to replace traditional refractory products, achieving long-term energy savings and significant economic benefits.
