Calcium Silicate Custom Shapes
Engineered Thermal Protection, Ready to Install
Stop cutting, grinding and wasting expensive block insulation.
RG Calcium Silicate Custom Shapes are CNC-machined or pre-cast to your exact drawing—so every pipe, vessel, turbine casing or furnace component receives a precision-fit insulation piece that lands on-site ready to install.
Why Plant Engineers Specify Our Shapes
-
Zero compromise fit – tolerances to ±0.5 mm; eliminates hot spots & heat leak paths
-
Up to 1000 °C (1832 °F) continuous – low thermal conductivity (≤0.065 W/m·K @ 400 °C) keeps surface temperatures safe and heat loss minimal
-
Non-combustible & asbestos-free – Euro-class A1 fire rating; meets ASTM C533, ISO 8143
-
Built-in strength – >1.5 MPa compressive strength; won’t sag, shrink or powder under load
-
Rapid install = lower labor cost – no on-site dusting, cutting or special tools; shapes key together in minutes, not hours
-
Chemically inert – resists oil, alkalis, most acids; ideal for chemical & offshore environments
Typical Applications
-
Steam tracing & header insulation
-
Pre-fabricated pipe shoes / saddles
-
Turbine & exhaust duct liners
-
Reactor head covers & flange insulation pads
-
High-temperature gaskets & heat shields
