CASI Nano Insulation Brick

High-Performance, Budget-Friendly Lightweight Insulation Brick
The CASI Nano Insulation Brick is a cost-effective, high-performance, and low-temperature insulation brick. It performs better than traditional bricks in weight, strength, heat insulation, and durability, while also offering a better price.
Key Features

Very Lightweight & Strong – With a bulk density of just 0.3 g/cm³, this brick is one of the lightest on the market, yet it keeps good strength.
Great Heat Insulation – Its thermal conductivity is over 30% lower than standard perlite bricks, lightweight clay bricks, or diatomite bricks.
Better Heat Resistance – Can handle 100°C higher reheating temperatures than common insulation bricks, helping keep shape and strength over time.
Consistent Quality – Made with automated machines, every brick has even density and exact size.
Safe & Clean – No fibers, asbestos, or harmful materials. Safe to handle and install.
Long Life Use – Fewer repairs needed and lower total cost over the brick’s working life.

Smart Materials & Technology

Made from top-quality alumina (Al₂O₃), silica (SiO₂), and lime (CaO), this brick is built using nano technology to create tiny lightweight particles. This gives it strong insulation and good strength in one product.

Where to Use It
The CASI Nano Insulation Brick is a great fit for:

Industrial furnaces and kilns that need energy-saving insulation
Equipment where lighter weight is important
Systems that need even and steady heat protection

Common uses include:

Roller hearth kilns
Tunnel kilns
Glass furnaces
Hot blast stoves
Reheating furnaces
Aluminum smelters
Carbon baking kilns
Flues and hot air ducts

This brick mixes the strength of standard fire bricks with the heat-saving benefits of insulation wool, making it a solid choice for saving energy, cutting weight, and improving furnace design.

Product Grades

Z1000 – Ultra-light (0.3 g/cm³), good for cutting furnace weight and keeping heat loss low.
Z1100 – Handles higher heat (up to 1000°C) than regular low-temp bricks.
Z1100H – A stronger Z1100, made for tougher conditions.
Z1200 – Meets ASTM Grade 20, with lower density and better insulation than typical products.
Z1250 – Similar to Grade 23 IFB, with extra insulation boost as CaCO₃ breaks down when heated – making it even lighter and cooler without harming structure.
