Introduction: 

Centrifugal glass wool is a silk-like material made by fiberization in the TEL process and spraying of thermosetting resin.  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.We offer high quality glass wool felt in rolls that is soft, waterproof and fireproof with good elasticity (a veneer of reinforced aluminum foil can be applied), providing an ideal thermal and sound insulation for steel structure constructions. The glass wool felt offers the advantages of low material cost, short work cycles and fine appearance. It is also friendly for worker safety as it is non-toxic and non-irritant to skin.

glass wool products are categorized in boards or panels, felt and tubes in various color. The panels may feature a layer of reinforced aluminum foil for enhanced exterior appearance, and are ideal for the insulation of production or storage facilities for minimum cost, yet nice appearance and effective insulation.
