Is foam glass and glass wool the same thing?

Foam glass:
Foam glass, also known as porous glass, is a kind of thermal insulation glass material consisting of numerous closed bubbles with porosity of more than 90%. Foam glass is produced with waste glass, fly ash, mica, perlite, pumice powder, volcanic ash, etc. as the main raw materials. It is an ideal wall sound absorption, thermal insulation and partition material for housing buildings, especially for new buildings, high-rise and super high-rise buildings rising in the world in the 21st century.
Foam glass was first invented by Corning Company in Pittsburgh, the United States. The production process consists of broken glass, foaming agent, modification additive and foaming accelerator. After fine crushing and uniform mixing, it is made of inorganic non-metallic glass materials through high temperature melting, foaming and annealing. The varieties include white, various degrees of yellow, brown and pure black.
Glass wool:
Glass wool is a product made by centrifuging molten glass fibers and processing them with an environmentally friendly formula adhesive mainly composed of thermosetting resin. It is an elastic plate-like body made of glass fibers with a diameter of only a few microns, and different moisture-proof veneers can be selected for online composite according to usage requirements. It has a large number of tiny air pores, which make it the best material for thermal insulation, sound absorption, noise reduction, and safety protection in steel structure buildings.
Glass wool belongs to a category of glass fibers and is an artificial inorganic fiber. Using natural ores such as quartz sand, limestone, and dolomite as the main raw materials, combined with some chemical raw materials such as soda ash and borax to melt into glass. In the melted state, with the help of external force blowing, it is thrown into a flocculent fine fiber, and the fibers intersect in a three-dimensional manner, intertwining with each other, presenting many small gaps. This gap can be regarded as a pore. Therefore, glass wool can be regarded as a porous material with good insulation and sound absorption properties.
Centrifugal glass wool has fluffy and interlaced fibers inside, with a large number of tiny pores, making it a typical porous sound-absorbing material with good sound absorption properties. Centrifugal glass wool can be used to make wall panels, ceilings, spatial absorbers, etc., which can absorb a large amount of sound energy in the room, reduce reverberation time, and minimize indoor noise.
Product advantages
Sound absorption and noise reduction can effectively prevent sound propagation.
Simple construction and flexible cutting.
Antibacterial and mildew resistant, aging resistant, corrosion-resistant, ensuring a healthy environment.
A1 level fire protection, permanently non combustible.
Low moisture content, high durability.
Nowadays, glass wool board has been widely used for insulation, heat insulation, sound absorption, noise reduction of building exterior walls, and insulation of industrial kilns; The interlayer of steel insulation board, etc.
Scope of Application
Thermal insulation and sound-absorbing cotton are suitable for various commercial, industrial, and residential buildings for heating, ventilation, tanks, air conditioning, and other purposes. They are used for noise reduction.
