Ceramic Fiber Products: Blankets, Modules, Boards

Selection Guide

Choosing the Right Ceramic Fiber Product

Ceramic fiber is supplied in four forms. The right one depends on whether the lining needs to flex, to carry load, or to fit a tight space.

By product form

Blanket — flexible needled fibre in roll form. The standard choice for furnace linings, pipe wrap and general insulation.
Module — pre-compressed folded blanket with an internal anchor. Fastest to install and the best choice for large furnace walls.
Board — rigid vacuum-formed panel. Use where the lining must be self-supporting or resist gas velocity.
Paper — thin flexible sheet from 1 mm. Use for gaskets, expansion joints and tight-clearance details.

By temperature grade

All four forms are available in COM, ST, HP, HA and HZ grades, covering continuous working temperatures from 1000°C to 1350°C. The working temperature — not the classification temperature — is the number to design to.
