Usage
Though the individual fibers conduct heat very well, when pressed into rolls and sheets, their ability to partition air makes them excellent heat insulators and sound absorbers. Though not immune to the effects of a sufficiently hot fire, the fire resistance of fiberglass, stone wool and ceramic fibers makes them common building materials when passive fire protection is required, being used as spray fireproofing, in stud cavities in drywall assemblies and as packing materials in firestops.
Mineral wools are unattractive to rodents, but will provide a structure for bacterial growth if allowed to become wet.
Other uses are in resin bonded panels, as a growth medium in hydroponics, as filler in compounds for gaskets, in brake pads, in plastics in the automotive industry and as a filtering medium.
Mineral fibers are produced in the same way, without binder. The fiber as such is used as a raw material for its reinforcing purposes in various applications, such as friction materials, gaskets, plastics and coatings.
The heat the material can withstand is:
| Material | Temperature |
|---|---|
| Glass wool | 230 - 250°C |
| Stone wool | 700 - 850°C |
| Ceramic fiber wool | 1200°C |

Famous quotes containing the word usage:
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
