What is asbestos and where it has often been used

Asbestos is a natural fibrous mineral, and is operated in a number of countries around the world.  Historically, it was a mineral that is popular for use in the construction due to the fact that it is sustainable, flexible, resistant to chemical attack, excellent insulation and capable of withstanding high temperatures.  Even the name itself comes from the Greek language where it means "one-extinguishable."


To the United Kingdom, asbestos has been used since the industrial revolution, when it was first used as insulation.  Since then, it has been used in various applications such as fire-retardant coatings, bricks, pipe and lining of boiler lagging.


There are three main forms of asbestos that occur naturally.  The first is called "chrysotile", or asbestos white and is the most commonly used type.   It was generally mixed with cement to form sheets of roof, corrugated, or used to make flat sheets for walls and floors.  Extremely flexible, it can be spun and woven as the fabric which makes it ideal as clothing or insulation same fire proof.  Considered to be dangerous for health, was prohibited at the United Kingdom in 1999.  It is estimated that this type represents up to 95% of all asbestos in buildings.


The second type of asbestos is called "amosite", or brown asbestos.  In buildings, most often found covering steel as protection against fire or walls as soundproofing.  This type of asbestos is also considered dangerous, and the importation of amosite has been prohibited in 1986.


The third form of asbestos is called "crocidolite", or blue asbestos.  It is a form more difficult and less flexible than other types, but it is extremely strong and has a high acid resistance.  He is considered the most dangerous of all types of asbestos, and its use is strictly controlled, 1969 until it was finally banned in 1986.


It is essential that when asbestos he finds it is deleted and removed correctly by a professional, licensed business of asbestos removal, as the deletion process can expose you health risks if the correct procedures are not followed.


Asbestos has been used for more than a century, it has been included in thousands of products.  The list below gives some of the common uses for asbestos containing products so that you know what we must be vigilant to make changes to a property.  Whereas asbestos is generally safe if left alone, any damage can lead to the release of fibres which are dangerous for health.


Panels and tiles - asbestos is commonly mixed with concrete to make the flat or corrugated panels.  They are often considered the roofs or walls of the outbuildings and garages.


Roofing felt - asbestos are combined with bitumen in the often found felt covering the flat roofs, where it gives flexibility and insulation.  Some products of bitumen containing asbestos were also used to gutters.


Lagging - addition of asbestos permits tissue to lag pipes and to prevent loss of heat or frost damage.  Similar material was also used for fire blankets and protective clothing.


Soundproofing - sprayed asbestos can often be found in sub floors and the ceiling void where it acts to prevent noise pollution.


Electrical insulation - asbestos paper was used to wrap in the back of the boxes of fuses its non-flammable properties and electrical wiring.


Spray coating - asbestos spraying on structural components of buildings offer of protection against damage caused by heat and cold.


Loose of packaging - wall and ceiling in the old buildings cavities may contain asbestos that it has been used frequently as insulation.


Door trim - a flat sheet of asbestos in door panels provides fire resistance.
