Glass wool is a kind of glass fiber and a kind of artificial inorganic wool. Adopting such natural ores as quartz sand , limestone , etc as the main ingredients and then coordinating with some chemical materials such as soda ash and borax, etc, the glass is hence melted .Under the melting condition , floccular fibril is made via external force and below , The fly-over crossing is taken on between fibers and then they are intertwined.Thus many fine gaps are showed out , these gaps can be regarded as pore spaces.Therefore, the the glass wool can be taken on as porous material with excellent thermal insulation and sound absorption performance.
