The Fiberfrax® Durablanket® family of lightweight

needled blankets are manufactured

from Fiberfrax® refractory ceramic fibres and

provide effective solutions to a wide spectrum

of thermal management problems.

Utilizing our proprietary high output blowing and

spinning techniques these products offer superior

insulating performance, flexibility and resilience.

Fiberfrax Durablanket products are unaffected by

most chemicals (except hydrofluoric & phosphoric

acids and concentrated alkalis). Thermal and

physical properties are retained after drying

following wetting by oil, steam or water.

Fiberfrax Durablanket products are completely

inorganic, so there are no fumes when heating for

the first time. Available in a variety of chemistry,

density and thickness combinations, the Fiberfrax

Durablanket range is one of the most versatile

available to the market today.
