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.
Asbestos shingles. Very long lifespan, fireproof, and low cost but now rarely used because of health concerns. [5] Stone slab. 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 ...

Things that typically might contain asbestos: [33] Boiler and furnace insulation. Heating duct wrapping. Pipe insulation ("lagging"). Ducting and transite pipes within ...
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.

Asbestos turned out to be harmful to health and produces mesothelioma, a form of lung cancer, years after professional or occasional exposure . Starting from the seventies, asbestos use became progressively prohibited; however, in several countries, it is still used for building materials.
The most common materials for corrugated iron are ferrous alloys (e.g. stainless steels), aluminium and copper. Regular ferrous alloys are the most common due to price and availability. Common sizes of corrugated material can range from a very thin 30 gauge (0.012 inches, 0.3 mm) to a relatively thick 6 gauge (0.1943 inches, 5 mm). Thicker or ...
