Types of asbestos

Types of Asbestos

Asbestos has been included in many materials in the last 150 years.  Three common types of asbestos can be found in buildings: 

  1. Crocidolite (Blue Asbestos), typically found in sprayed coatings, pipe insulation and cement-based products was banned in 1985. 
  1. Amosite (Brown Asbestos) is usually found in asbestos insulating boards (AIB) and was banned in 1985. 
  1. Chrysotile (White Asbestos) was legal until 1999 and banned thereafter. Often found in cement-based products, artex and floor tiles, Chrysotile can be found in insulation materials and insulating board (AIB). 

Asbestos, in loose or contained form, can be found within: 

  • Cement items such as roofing 
  • Insulation Boards 
  •  Thermal Insulation 
  • Rope Insulation, Lagging and Yarns 
  • Floor Tiles, textiles, and composite products 
  • Textured Coatings 
  • Loose in cavities, floors, and ceilings 
  • Demolition 
  • Land Surveying 

Asbestos cement

Generally containing 10-15% asbestos fibres which are bound in Portland cement or calcium silicate. Uncoated sheets, widely used in the past as a building material can be identified as light grey in colour. 

Whilst they were banned in 1999, asbestos cement products are the most common application of asbestos.  Many houses, especially if built between the 1940s and the mid 1970’s, will have asbestos cement garages and other asbestos cement products within and around the house.

Asbestos millboard

Millboards manufactured between 1896 and 1965 can contain chrysotile asbestos (up to 97%).

  • Often found in: Pipe runs, electrical gear, vaults, storage.
  • Often used for:  General heat insulation and fire protection. Also used for insulation of electrical equipment and plant.

Asbestos sprayed coatings

Are contained within products that can generate very high fibre levels if disturbed.

  • Often found in: Roof underlining (especially on asbestos cement roofs), service risers, floor voids, ceiling voids and around firebreaks,
  • Often used for: Fire protection on structural supports (eg columns and beams), fireproofing and soundproofing.

Asbestos floor tiles

  • Often found in: Floors roofs, floors, external walls, under stainless steel sinks,
  • Often used for: Floor Coverings, mastic, adhesive, roof felt, sink pads

Asbestos Lagging, Ropes & Yarns

Where used for lagging or packing material ropes and yarns can contain 40 – 100% asbestos depending on its functional requirements.

  • Often found in: Pipework, windows, boilers and ovens, on electrical equipment
  • Often used for: Pipe lagging, insulation, jointing pipes, heat resisting situations.

Textured coatings

May contain asbestos and if well bonded and fibres are not often easily released. However, because of the asbestos content it to be worked with safely.
