Usually, wool thickness is15MM 25MM 30MM 40MM or 50MM .. Unit weight is 12K 16K 24K 32 or 48K. Glass wool with high unit weight should be reserved. And the price depends on the purposes.

Glass wool, a man-made inorganic fiber, belongs to a kind of glass fiber. It is a spongiform material made through fibration of melten glass. It is an inorganic fiber whose chemical components belong to glass, having good formability, low bulk density, low thermal conductivity, good thermal insulation and sound absorption, corrosion resistance and chemical stability. For centrifugal glass wool whose thickness exceed 5 cm and unit weight is 16Kg / m3, the sound absorption coefficient of low frequency125Hz is about 0.2, and that of middle and high frequency is close to 1. When the thickness continues to increase from 5cm, the low-frequency sound absorption coefficient also increase gradually. When the thickness is greater than 1m or more, 125Hz low frequency sound absorption coefficient will also be close to 1. Thicknesses of acoustic glass wools often used in architectural acoustics are 2.5cm, 5cm, 10cm, and unit weights are16,24,32,48,80,96,112kg / m3. centrifugal glass wool whose thickness is 5 cm and unit weight is 12-48kg / m3 is usually used.
