Refractory Fibre

9 - refractory fibre

Description

Refractory Fibre insulations are mineral or ceramic fibres, including alumina and silica, bonded with extremely high temperature inorganic binders, or a mechanical interlocking of fibres eliminates the need for any binder. The material is manufactured in blanket or rigid form.

The material is non-combustible and has tremendous high temperature characteristics.

If the material has been placed in service, there is serious potential health issues associated with its removal. It has to be treated like asbestos to be removed safely. Consideration should be given to using other materials where possible. If it is an extremely high temperature application refractory fibre may be the only suitable material.

Consideration should be given to using this material in combination with other lower temperature materials (such as fibreglass or mineral fibre) in the outer layers to reduce cost and reduce the use of refractory fibre.
