High-temperature calcium silicate pipe insulation made from xonotlite hydrate and reinforcing fibers. Asbestos-free with a maximum service temperature of 1050°C. Pre-formed half-shells designed for easy installation on pipes, boilers, kilns and industrial equipment — also available as custom-shaped segments.
Withstands continuous thermal loads within its temperature limit. Does not powder over long-term service.
Excellent insulation performance across the entire operating temperature range.
High strength-to-weight ratio. Reduces load on pipe supports and equipment structures.
Contains no asbestos, sulfur or chlorine. Safe for workers and the environment.
Unaffected by moisture. After drying, performance remains unchanged — no degradation.
Can be cut and shaped with ordinary woodworking tools. Fast on-site installation.
Protects high-temperature pipes and vessels from heat loss and surface corrosion.
Available as half-shells, segments, elbow and valve covers — made to your pipe dimensions.
