Balance between thermal insulation and mechanical strength

Monolux sheets and machined parts, made from high-density calcium silicate, are specially designed for industrial environments subject to high temperatures. They combine high thermal performance, dimensional stability and superior mechanical strength, making them ideal for critical applications.

Main applications :

Insulation and lining for industrial furnaces (melting, heat treatment, incineration).
Cladding for furnaces and hot chambers requiring high mechanical strength.
Custom-made holders for electrical resistors and insulating parts.
Buildings requiring rigid insulating panels for extreme temperatures (glassworks).
Replacement of fibrous panels in environments where a rigid solution is required.
