Friable vs non-friable asbestos

Asbestos-containing materials fall into two broad categories: non-friable and friable.

'Friable' is used to refer to asbestos-containing materials that can be easily reduced to powder by hand, when dry. These materials are more likely to release measurable levels of asbestos into the airborne environment when disturbed, and generally pose a greater risk to health. Examples of friable asbestos-containing materials include:

  • sprayed asbestos fire retardants
  • thermal lagging, such as pipe insulation
  • low density boards
  • sheet vynil underlay or backing

'Non-friable', or bonded asbestos is used to refer to asbestos-containing materials in which the asbestos is firmly bound in the matrix of the material. These materials are unlikely to release measurable levels of asbestos fibre into the airborne environment if they are left undisturbed. Therefore, they generally pose a lower risk to health. Examples of bonded asbestos-containing materials include:

  • asbestos cement products (flat and corrugated sheeting used in walls, ceilings and roofs, moulded items such as downpipes)
  • vinyl floor tiles (however removal of the glue can be classed as friable)

Because of its strength and its ability to resist heat and chemicals, asbestos was used in a range of insulation materials.
