While home insulation remains one of its most common applications, the name itself has become a generic term for any material containing thin fibers of glass formed into a woven layer or used as reinforcement.

   The 20th century is the 20th group of 100 years, so it ended at  2000. If the century and the the digits they start with were the  same, I.E. the 19th Century was the years 1900 to 1999, then by  default the 1st Century would have to be the years 100 to 199.irst, the 1900s are slightly out of alignment  with the 20th century which is why peopl â¦ e confuse them. You are not  referring to the same years. So the 1900s refers to 1900 to 1999  whereas the 20th century refers to 1901 to 2000.
