Features

Features

Effective Thermal Barrier

Laurel’s castable refractory insulation exhibits low thermal conductivity, providing a highly efficient barrier that minimizes heat loss and supports uniform temperature control inside industrial furnaces.

Lightweight with Structural Strength

These insulating refractory castables reduce overall lining weight, improving installation flexibility and lowering the thermal mass without compromising the system’s structural performance.

Reliable in Thermal Cycling

Formulated for thermal stability, the castable ceramic insulation maintains integrity under frequent temperature fluctuations, preventing cracking and degradation during thermal cycling.

Easy Application Methods

All Laurel castable refractory insulation materials are provided as dry mixes and are suitable for casting, pumping, or gunning, ensuring rapid and adaptable installation in both new builds and repair projects.
