At Oryvia Refractories, we provide industrial refractory and thermal insulation solutions for demanding industrial environments. Our Calcium Silicate Insulation Products are designed for applications where effective heat insulation, structural stability and suitable mechanical strength are important considerations. Calcium silicate is an inorganic insulation material commonly used in industrial thermal management systems, including furnace insulation, process equipment and high-temperature piping applications.
Calcium silicate insulation is primarily composed of hydrous calcium silicate and may incorporate fibrous reinforcement, depending on its formulation. Its rigid structure and insulation characteristics make it suitable for applications requiring preformed insulation materials that maintain their shape under appropriate operating conditions.
Calcium silicate insulation materials are selected for their combination of thermal and physical properties. Their performance depends on material formulation, density, operating temperature and product configuration.
Calcium silicate insulation materials are used in industrial installations where suitable thermal insulation and mechanical characteristics are required. Depending on the selected grade and product form, relevant applications include:
Application suitability should always be evaluated according to the operating temperature, equipment design, material grade and relevant installation requirements.
