Asbestos is widely used in roofing materials, mainly corrugated asbestos cement roof sheets and asbestos shingles sometimes called transite. Other sources of asbestos-containing materials include fireproofing and acoustic materials .
The roof is sheeted with corrugated fibro sheets and the walls with flat fibro sheeting, with fibro battens covering the joints. Example of asbestos cement siding and lining on a post-war temporary house in Yardley, Birmingham. Nearly 40,000 of these structures were built between 1946 and 1949 to house families.
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 ...
Construction workers who inhale asbestos from contaminated building materials such as paint, spackling, roof shingles, masonry compounds, and drywall may get asbestosis. The amount and length of an individual's exposure to asbestos are the primary factors that determine the level of risk.
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.
The asbestos removal may take longer and cost more than the actual demolition. For example, the former seat of parliament of East Germany, the Palast der Republik, was stripped of most of its asbestos between 1998 and 2001, before it was finally demolished starting in 2006. The Utah State Prison underwent a full asbestos removal before its ...
It can also be found in insulation, siding, roof gutters, and cement wallboard. The more prevalent transite found in wall construction and roofing tiles for example, will last anywhere from 50 years to over 100 years. [citation needed] The use of asbestos, a proven carcinogen, to manufacture transite was phased out in the 1980s.
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
