What is glass wool?
Glass wool is a kind of thermal insulation material, which belongs to a category of glass fiber and is a kind of man-made inorganic fiber. Glass wool is a material made by fiberizing molten glass to form a cotton-like material. The chemical composition is glass and it is an inorganic fiber. It has good molding, low volume density, high thermal conductivity, thermal insulation, good sound absorption performance, and corrosion resistance. Corrosion-resistant and chemically stable.
Why use glass wool?
Glass wool is a very good fireproof and thermal insulation material. Thermal insulation can effectively reduce energy consumption, improve the comfort and quality of life of the building, make your building warm in winter and cool in summer, achieve energy saving and emission reduction, and slow down the global climate. warming;
In addition, our thermal insulation materials have excellent fire protection and can improve fire safety;
The biggest feature and advantage over other insulation materials is that glass wool has sound absorption and noise reduction properties.
