rolls packaging glass wool has good insulation and sound performance.

rolls packaging glass wool is a category that is a man-made inorganic fibre.

It is made of by the quartz sand,limestone,dolomite and other natural crystal.

With a soda ash boron , the chemical materials for having melted into the glass.

Crystals glass fiber is a porous material of a sound performance.

The reason of crystals glass fiber absorbs the sound is not because the surface, but because it has a lot of internal and external connectivity which is a tiny pore and opening.

The affection  of glass fiber as a sound performance of the main factor is the thickness, the air flow resistance and so on.

Air flow resistance is most important factor to affect to crystals glass fiber of sound performance .

Flow resistance is too small, thin air, the material is easy to pass through, the sound performance declines,flow resistance is too big and thick material, it is introduced into the air, the sound performance also drops.

The sound performance of glass fiber is closely related to the  installation conditions.

When the air layer  behind glass  fiber ,it has the similar  sound effecttion to the same thickness glass fiber with no air layer.

Glass fiber  can prevent mildew,good antimicrobial resistance and slushing ,and it can ensure healthy environment.

It is extensively used in industrial buildings, conservatory, public facilities, exhibition center, shops, and all kinds of the playground, and sports venues and buildings of the heat insulation and sound.

On application to the cost at the same time, the beauty, and fire, moisture, dust for many problems and aging should be taken into account.
