After the ban, popcorn ceiling materials were created using a paper-based or Styrofoam product to create the texture, rather than asbestos. Textured ceilings remain common in residential construction in the United States. Since the mid-2000s, the popularity of textured popcorn ceilings has diminished significantly across North America.

For example, a popcorn ceiling is extremely friable, whereas asbestos floor tile is considered non-friable. [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.
It’s very important to test your ceiling for asbestos before you disturb it. If a popcorn ceiling was put in before 1989, “then it is going to come back positive for asbestos 99 percent of the ...

The use of crocidolite (blue asbestos) was banned in 1967, while the use of amosite (brown asbestos) continued in the construction industry until the mid-1980s. It was finally banned from building products in 1989, though it remained in gaskets and brake linings until 31 December 2003, and cannot be imported, used, or recycled.
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 ...
Asbestos cement, genericized as fibro, fibrolite (short for "fibrous (or fibre) cement sheet"; but different from the natural mineral fibrolite), or AC sheet, is a composite building material consisting of cement and asbestos fibres pressed into thin rigid sheets and other shapes.
