The fireproof inspection results meet the requirements of A2 in GB 8624-2006 and can be directly used for indoor fire prevention.
As it has the advantages of fireproof and anti-corrosion performance, no toxicity, small volume weight, low heat conductivity, strong chemical stability, and good hydrophobicity etc., it is considered the best heat preservation, heat insulation, sound absorption and noise reduction material with significant effect, and can be widely used.

With natural ores as the main raw materials, e.g. quartz sand, limestone and dolomite, along with some chemical substances like sodium carbonate and borax, the centrifugal glass wool is smelted into the glass. In the melted state, it is blown by external forces to be flocculent fine fibres, which cross and intertwine each other with many small gaps in between. As the fluffy fibres cross each other, there are abundant small holes, and thus it is a typical perforated sound absorption material with good sound absorption properties.
The centrifugal glass wool can be made into wall sheets, ceiling sheets and spatial sound absorbers, etc. to largely absorb the sound energy in the rooms to reduce the reverberation time and the indoor noise. When there is a layer of air behind the glass wool sheet, the sound absorption effect is similar to that of the glass wool sheet of the same thickness without the air layer. In particular, the sound absorption performance for the medium and low-frequency sound signals will be much better than that of hard bottom surfaces with attached materials.
The sound absorption coefficient will increase along with the increase of the thickness of the air layer. Through the superposition of glass wool of different volume weight values to gradually increase the total volume weight, even better sound absorption effect can be achieved.
