ëë¤. 200 Grover Street  Fiberglass used for insulating appliances appears to produce human disease that is similar to asbestosis. Fiberglass will irritate the eyes, skin, and the respiratory system. a method similar to making cotton candy, by forcing it through a fine mesh by centripetal force, cooling on contact with the air. Fiberglass insulation has been used in homes since the 1930s and was first created by the Owens Corning Company. When inhaled, particles can cause coughing, nosebleeds, and other respiratory ailments. Commonly known as think pink aerolite. How Much Does Fiberglass Insulation Cost? Glass wool is a thermal insulation material consisting of intertwined and flexible glass fibers, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content (as noted above, these air cells are the actual insulator). Potential symptoms include irritation of eyes, skin, nose, and throat, dyspnea (breathing difficulty), sore throat, hoarseness and cough.
