Insulation firebricks, also known as insulation bricks, are a different class of refractory. They are made from high purity refractory clay which gives them insulative properties and other characteristics, making them ideal for an array of applications.
- More lightweight and less dense than fireclay bricks
- Provide superior insulation to dense firebricks (though structurally are weaker)
- Low thermal mass and hence are suitable for applications where heat storage is undesirable
- Chimney linings
- Hot-face linings within ceramic kilns
- Brazing hearths
- Heat treatment furnaces
