Description
Finely spun glass fibers sold commercially as a white fluffy mass or a loose blanket. Glass wool was patented in the US in 1933 by a method made by Games Slayter at the Owens-Illinois Glass Co. The fibers are approximately one-thousandths of an inch in diameter (1 mil) and are held in a foam-like mesh that traps tiny air pockets. This results in lightweight material with very high thermal insulation. Glass wool is used for filtration, thermal insulation and as a decorative media. It is resistant to mold growth, even at high humidity.
