Asbestos insulating board (AIB), also known by the trade names Asbestolux and Turnabestos, is an asbestos-containing board formerly used in construction for its fire resistance and insulating properties. [1] These boards were commonly used in the United Kingdom from the 1950s until production ended in 1980.
The business was founded in 1871 in Rochdale as Turner Brothers by John, Robert and Samuel Turner to manufacture cotton-cloth-based mechanical packing. [2]In 1879 it became the first business in the United Kingdom to weave asbestos cloth with power-driven machinery, and the company changed its name to Turner Brothers Asbestos Company.
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...
In construction, asbestos abatement is a set of procedures designed to control the release of asbestos fibers from asbestos-containing materials. [1] Asbestos abatement is utilized during general construction in areas containing asbestos materials, particularly when those materials are being removed, encapsulated, or repaired.
Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet"; but different from the natural mineral fibrolite), or AC sheet, is a composite building material consisting of cement and asbestos fibres pressed into thin rigid sheets and other shapes.
In 1976 it established a scaffolding division [5] and in the late 1970s it developed asbestos-free products such that by 1980 it had become the world's foremost supplier of asbestos-free protection and insulation board. [6] Although it had a full listing during the 1980s it was at that time 67.3% owned by Charter Consolidated plc. [6]
The asbestos fibres are intimately bound to the cement matrix and were considered to be immobilized in the cement and therefore less prone to be released in the environment, suspended in the air, and inhaled in the lung than in other materials or applications, such as thermal insulation or flocking, in which loose asbestos fibres were used.
The most common asbestiform mineral is chrysotile, commonly called "white asbestos", a magnesium phyllosilicate part of the serpentine group. Other asbestiform minerals include riebeckite, an amphibole whose fibrous form is known as crocidolite or "blue asbestos", and brown asbestos, a cummingtonite-grunerite solid solution series.
