Calcium Silicate Blocks
Calcium Silicate Blocks are high-strength, non-asbestos insulation panels engineered for applications where both thermal resistance and mechanical load-bearing capacity are required simultaneously. Unlike soft fiber-based insulation, calcium silicate maintains its structural form under compressive loads, making it the preferred backing insulation for large industrial vessels, boilers, and high-pressure piping systems. Imperial World Trade supplies calcium silicate blocks that meet international standards for thermal performance and compressive strength, serving power plants, refineries, and petrochemical facilities across 55+ countries.
- High Compressive Strength: Withstands mechanical loads from outer cladding and pipe supports without deformation or cracking.
- Temperature Range: Available in grades suitable for continuous service up to 1,000°C.
- Moisture Resistance: Low water absorption prevents thermal performance degradation in humid industrial environments.
- Non-Asbestos Composition: Fully compliant with international health and environmental regulations.
- Dimensional Stability: Minimal shrinkage at operating temperature ensures consistent insulation thickness throughout service life.
- Lightweight: Significantly lighter than equivalent refractory brick, reducing structural load on vessels and supports.
- Easy Machining: Can be cut, drilled, and shaped on-site using standard woodworking tools.
Imperial World Trade’s Calcium Silicate Blocks are supplied with verified thermal conductivity data and compressive strength certificates, giving your engineering team confidence in every insulation layer specification.
