The Difference Between Glass Wool And Rock Wool

Dec. 23, 2019

Today, the supplier of Sound Absorption Ceilling Board shares the difference between glass wool and rock wool.


Glass wool is a product made of centrifugal glass wool felt and melted glass fiber, and is made of environmentally-friendly formula binder based on thermosetting resin. It is an elastic product made of glass fiber with a diameter of only a few microns. Felt-shaped body, and different moisture-proof veneers can be selected for online compounding according to the requirements of use. It has a large number of tiny air pores, making it play the role of heat insulation, sound absorption and noise reduction and safety protection. It is the best material for steel structure building insulation, sound absorption and noise reduction. Glass wool belongs to a category of glass fiber and is an artificial inorganic fiber. Quartz sand, limestone, dolomite and other natural ore are used as the main raw materials, and some soda ash, borax and other chemical raw materials are used to fuse into glass. In the melted state, they are blown into flocculent fine fibers by means of external force blowing. The fibers and fibers are three-dimensionally intertwined and entangled with each other, showing many small gaps. This gap can be considered a void. Therefore, glass wool can be regarded as a porous material, which has good thermal insulation and sound absorption properties.


Rock wool: Cotton originated in Hawaii. After the first volcanic eruption on Hawaii Island, residents of the island found a ray of melted soft rock on the ground. This is the rock wool fiber originally recognized by humans.

Production process differences between Glasswool Acoustic Panels and rock wool insulation boards:


Glass wool belongs to a category of glass fiber and is an artificial inorganic fiber. Quartz sand, limestone, dolomite and other natural ore are used as the main raw materials, and some soda ash, borax and other chemical raw materials are used to fuse into glass. In the melted state, they are blown into flocculent fine fibers by means of external force blowing. The fibers and fibers are three-dimensionally intertwined and entangled with each other, showing many small gaps. This gap can be considered a void. Therefore, glass wool can be regarded as a porous material with good.


Thermal insulation and sound absorption. Glass wool is a material that melts molten glass to form a cotton-like material. Its chemical composition belongs to glass and is an inorganic fiber. It has good molding, small bulk density, low thermal conductivity, heat insulation, sound absorption, and corrosion resistance. Decoration and chemical properties are stable. Rock wool products such as Rock Wool Pipe are made of refined basalt as the main raw material. After being melted at high temperature, they are made of inorganic fibers by high-speed centrifugal equipment, and then special adhesives and dust-proof oil are added. Arranged structure, a new type of lightweight thermal insulation material made by curing and shaping. According to different purposes, it can be processed into rock wool board, rock wool seam felt, rock wool tube shell and other products. Product performance difference between rock wool insulation board glass wool insulation board and rock wool insulation board Glass wool has a lower specific weight than rock wool, less slag ball content, low thermal conductivity, long service life and high fiber toughness, but the high temperature of rock wool is About 600 degrees Celsius, glass wool is only about 260 degrees Celsius. Product difference between glass wool insulation board and rock wool insulation board Glass wool is generally used for insulation parts below 200 degrees Celsius, mostly used for the insulation of general buildings or low-temperature pipelines. Rock wool is generally used for insulation parts at temperatures of 500 degrees Celsius It is mostly used for heat insulation of high-temperature heat pipes or power equipment.


The above is the difference between glass wool and rock wool, I hope to help everyone.
