What is glass wool? Glass wool is glass wool board, glass wool felt and glass wool tube form of heat insulation sound absorption material. It is made by mixing ultrafine glass fibers with a certain amount of adhesive after curing and forming. Glass wool is a very common product in our life. It is widely used in steel structures, air conditioning and ventilation ducts, insulation of train cars, as well as sound absorption treatment of theater and hotel walls.

Structure and sound absorption principle of glass wool:

Because the fiberglass inside the glass wool is very fine, there are many slender fiberglass that divide the air into air packets and well limit the air flow, which creates a lot of resistance to the air flow, and there is little air flow into it. After convection disappears, heat and static air have strong heat insulation, which makes the whole product has good heat insulation performance.

It is well known that sound is transmitted by vibrations in the air, which is similar to our principle of insulation. The openings in the surface of the glass wool product allow most of the sound to enter the glass wool product. The tremendous resistance of the airflow quickly weakens the vibration of the air, and the sound energy is converted from mechanical energy to heat energy and absorbed. Therefore, glass wool products show good thermal insulation performance.

 

What are the main advantages of glass wool?

Glass fiber slender, low thermal conductivity; Excellent sound absorption and noise reduction, can effectively prevent sound transmission; Grade A non-combustible material, high fire resistance; Strong hydrophobicity, excellent mildew resistance; Stable chemical properties, aging resistance, corrosion resistance; Light material, simple construction; Low cost price, cost-effective.

The above mainly introduces some important indicators of glass wool. I believe that through reading, you have a deeper understanding of glass wool.

With competitive price and timely delivery, Yunsheng sincerely hope to be your supplier and partner.

Glass Wool is a kind of glass fiber and a kind of artificial inorganic wool,adopting such ores as quartz sand ,iimestone,ect 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 blow,the fly-over corrssing 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 glass wool can be taken on as porous material with excellent thermal insulation and sound absorption performance.
