How is fiberglass made? (www.fiberglass.to/companyprofile.htm) Machines for creating fiberglass. "Let's begin with the chemistry of fiberglass insulation.� It is made from molten sand or recycled glass.� Have you ever seen cotton candy being made?� Making the wool-type fibers for insulation is similar.� The molten materials are poured into a spinning cylinder with thousands of tiny holes at the rim.� The fibers are created when the molten glass passes through the tiny holes.� The fibers are considered vitreous because they are glassy and non-crystalline.� Next the material is cured in ovens and then formed into the batts of pink stuff you've seen.� Did you know that as much as 40% percent of fiberlass insulation is actually recycled glass?� In addition, (www.metalbuildingsonline.com/insulation.htm) fiberglass insulation itself is naturally non-combustible."� (FitzPatrick, Sept. 2001, www.americanchemistry.com/chemmag.nsf/WebMagazineArticle?ReadForm&mfpk...)
