Q:Sound absorption and sound insulation How is the sound insulation effect of glass wool?
The sound insulation effect of sound-absorbing and sound-insulating glass wool is very good. Firstly, the quality of wall is good and durable; secondly, the sound insulation effect is very good, mainly because the sound absorption property of glass wool is good, which can cut off external sounds effectively.
Q:What is the construction process of external wall glass wool board?
Rock wool board should be pasted from the bottom up, in the horizontal direction it should be pasted from corners to windows to the sides; during pasting, it should be squeezed paste softly and evenly, internal and external corners should be rubbed and lapped; after finishing pasting, then check the flatness and perpendicularity with a 2 m ruler; rock wool board should be re-pasted if the tolerance is too large(the error is greater than 2 mm); when pasting around door and window openings, complete rock wool board should used, and the patchwork of rock wool board can not just be in the corners of window and door openings. Rock wool board pasted to corners should exceed the minimum size of 200 mm. I hope my answer help you.
Q:What are the differences between glass wool felts and rock wool board in terms of appearance, and how to distinguish them?
First, the color. environmental glass wool is while, while rock wool is dark.
Q:What environmental pollutions will be created during the production of glass wool?
It is quite dangerous. Glass wool is very small, such as phenol. If it gets into lungs,the health hazards in the exhaust gas are harmful. If it is on the skin, it will be atingle and itchy. During the production of glass wool, there will be formaldehydes and glass fiber dust.
Q:Whose thermal insulation performance is the best between glass wool felts and cystosepiments?
personally I believe that foamed concrete thermal insulation boards are better.
Q:How about the sound insulation performance of glass wool felts?
The direct relationship between sound level and the density of glass wool. It has sound absorption penetrability, also can be wall.
Q:What is the density of high-temperature glass fiber
glass wool density is generally between 16K ~ 32K, mainly used for acoustic and thermal insulation, but easily casues layering. Harmful substances comes out at the first heating. it is cheap. The density of the glass fiber acupuncture felt is 110~180kg/m3. It is mainly used for environmental protection, sound-absorbing. it has better fireproof property but it is more expensive.
Q:What are the industry standards of glass wool and its products?
Conventions of Quality Management of Enterprises producing Glass Wool and its Products by National Building Materials Bureau Chapter I General Provisions 1. In order to strengthen the quality management of enterprises producing glass wool and its products, and constantly improve quality of products, the cnventions are formulate in accordance to "Product Quality Law of People's Republic of China" and the relevant regulations of the State Council.

Capable enterprises should draw up "quality Manual", and seriously implement it.
Q:What is the difference between rock wool and glass wool?
Q:What are the purposes of centrifugal glass wool?
Glass wool felts, sound-absorbing cotton felts are an ideal sound absorption and thermal insulation materials which are widely used in walls, ship engine room insulation; computer rooms, cold storages with constant temperature; various generator rooms, pump rooms noise reduction; stereo cabinets, audio adjustments, etc. Function: sound absorption and insulation, as well as thermal insulation of walls.
