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.
Both indices use an arbitrary scale in which asbestos-cement board has a value of 0, and red oak wood has 100. [1] The tunnel test does not measure the ignitability of materials, nor does it properly assess the behavior of thermoplastic materials which may tend to melt and drip from the assembly, or for materials with slow flame spread properties.
Asbestos cement competed with aluminum alloy, available in large quantities after WWII, and the reemergence of wood clapboard and vinyl siding in the mid to late 20th century. Asbestos cement is usually formed into flat or corrugated sheets or into pipes, but can be molded into any shape that can be formed using wet cement.
Raw chrysotile asbestos was imported into the U.S. as recently as 2022 for use by the chlor-alkali industry, which makes asbestos diaphragms to make sodium hydroxide and chlorine, used to ...

Residential building materials containing asbestos include a variety of products, such as: stipple used in textured walls and ceilings; drywall joint filler compound; asbestos contaminated vermiculite, vinyl floor tile; vinyl sheet flooring; window putty; mastic; cement board; asbestos cement pipes and flues; furnace tape; and stucco.
By 1990, Owens-Corning was the defendant in about 84,500 asbestos-related lawsuits. [18] [citation needed] The company opened an Asia/Pacific division in 1993. [19] In May 1994, Owens-Corning acquired UC Industries, which produced Foamular polystyrene insulation, as a wholly owned subsidiary. [20] In 1996, the company changed its name to Owens ...
Despite asbestos-containing transite being phased out, it is still not banned in the United States; some 230,000 deaths have been attributed to it. [ citation needed ] Demolition of older buildings containing transite materials, particularly siding made from transite, requires special precautions and disposal techniques to protect workers and ...
