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 Why Buy From DEMINAS DEMINAS ceramic fibre blanket is manufactured to a consistent density and supplied with fast UK delivery. The material cuts cleanly with a straight knife and can be pinned, wired, or adhered in place without specialist tools. Contact us if you need a custom length or have an application question.
