Flat sheets for house walls and ceilings were usually 6 and 4.5 mm (0.24 and 0.18 in) thick, 900 and 1,200 mm (35 and 47 in) wide, and from 1,800 to 3,000 mm (71 to 118 in) long. Battens 50 mm (2.0 in) wide × 8 mm (0.31 in) thick, used to cover the joints in fibro sheets. "Super Six" corrugated roof sheeting and fencing.
Heavy stone slabs (not to be confused with slate) 1–2 inches thick were formerly used as roofing tiles in some regions in England, the Alps, and Scandinavia. Stone slabs require a very heavyweight roof structure, but their weight makes them stormproof. An obsolete roofing material, now used commercially only for building restoration.
Occupational health concerns and the protection of workers in the fibre-cement factories have finally led to the progressive elimination of asbestos from these products. [2] For health reasons, it is recommended that existing fibre-cement products that are in good condition are left undisturbed and possibly encapsulated, to prevent fibre release.
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 ...
Asbestos shingles are roof or wall shingles made with asbestos cement board. They often resemble slate shingles and were mass-produced during the 20th century as these were more resilient to weathering than traditional slate shingles for the reason that slate is very soft and prone to weathering.
Transite originated as a brand that Johns Manville, an American company, created in 1929 for a line of asbestos-cement products, including boards and pipes. [1] In time it became a generic term for other companies' similar asbestos-cement products, and later an even more generic term for a hard, fireproof composite material , fibre cement ...
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.
He mixed 90% cement and 10% asbestos fibres with water and ran it through a cardboard machine, forming strong thin sheets. Originally, the reinforcing fibres were of asbestos and the material was commonly used as siding in house buildings due to its low cost, fire-resistance , water tightness, light weight, and other useful properties.
