Product introduction of glass wool wall insulation

FANRYN Glass wool wall insulation belongs to a category of glass fiber, which is a man-made inorganic fiber. The main raw materials are quartz sand, limestone, dolomite and other natural ores, and some chemical raw materials such as soda ash and borax are used to melt into glass. In the melted state, the flocculent thin fibers are blown by the external force, and the fibers and the fibers are three-dimensionally intersected and entangled with each other, showing many small gaps. Such gaps can be regarded as pores. Therefore, glass wool can be regarded as a porous material with good thermal insulation and sound absorption properties.
