Full description

DEMINAS ceramic fibre blanket insulation delivers reliable thermal protection at temperatures up to 1260°C (2300°F). Made from spun alumina-silica ceramic fibres, the blanket has low thermal conductivity — meaning less heat passes through the insulation layer and energy loss in high-temperature processes is kept to a minimum.

Specifications

  • Maximum service temperature: 1260°C (2300°F)
  • Thickness: 25 mm
  • Width: 610 mm
  • Density: 96 kg/m³
  • Composition: Alumina-silica ceramic fibre
  • Asbestos-free

Key Properties

  • Low thermal conductivity — effective insulation at extreme temperatures
  • High tensile strength — resists tearing during handling and installation
  • Excellent resistance to thermal shock
  • Good sound absorption
  • Lightweight and easy to cut to shape on site
  • Resistant to most industrial chemicals

Typical Applications

Ceramic fibre blanket is used across heavy industry wherever high-temperature insulation is required:

  • Kiln and furnace lining, backup insulation, and door sealing
  • Outdoor oven insulation beneath a protective render coating
  • Industrial boiler lagging and expansion joint packing
  • Steel industry — tundish lining and ladle backup
  • Ceramic and glass industry heat treatment equipment
  • High-temperature ducting and ductwork insulation
