[citation needed] Friable materials, such as popcorn ceiling tiles, have a lifespan between 20–40 years plus; whereas non-friable materials, such as asbestos roofing tiles, have a lifespan of 50–100 years and beyond.
The application of this type of acoustic plaster to the ceiling is often known as the "popcorn ceiling" due to its aesthetic texture. [12] However, asbestos introduced health-hazards to the acoustic plaster, for both the users of space and especially for the workers installing the plaster. [12]

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.
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 boards, typically used in wall construction. It can also be found in insulation, siding, roof gutters, and cement wallboard. The more prevalent transite found in wall ...
