Glass wool is non-combustible, non-toxic, and resistant to corrosion. It has low weight by volume, low thermal conductivity, stable chemical property, and low moisture absorption rate due to its excellent hydrophobicity. Thanks to its intertwined flexible fibers, glass wool is the best insulating material against noise, cold and heat and also offers excellent fire-resistant properties. The panel, felt, and pipe products made of glass wool have been used in the industries of construction, chemical, electronic, energy, metallurgy and communication.
