Q:Which kind of soundproof cotton is the best for decorative gypsum board partition ? Mineral rock wool or glass wool?

Glass wool has better effect of sound insulation and is easier to construct but more expensive than rock wool. But there is no inspection report so there is no quality assurance if you use it.

Q:Is the glass wool sound insulating? How good is it?

Is it used on car?

Q:What is the difference between imported glass wool and rock wool?

Glass wool is categorized into glass fiber, which is a manmade inorganic fiber. Glass wool is a material which fibering melting glass to form cottony shape. Its chemical composition belongs to the classification of glass, being an inorganic fiber. So, it is good shaped with small volume density, low thermal conductivity, good thermal insulation and sound absorption properties, great corrosion resistance as well as stable chemical performance. Rock wool board is a manmade inorganic fiber which employs basalt as the material and is produced by melting process at high temperatures, keeping light in weight and low in small thermal conductivity with the features of heat-absorbing and non-flammability.

Q:Are there any differences between glass wool and rock wool in terms of appearance, I can't distinguish them, why?

They have different colors

Q:What industry does the glass wool belong?

Yes, generally speakingg, the glass wool often refers to the yellow centrifugal glass wool which is a fibrous material.

Q:Is centrifugal glass wool or rubber and plastic insualtion board better for air-conditioning air duct insualtion?

Glass wool is cheaper. Feel free to ask me more. the answer is provided by the Hebei Chengxin Chemical Building. Welcomed the consultation, if satisfied please adopt. Use rubber and plastic more.

Q:How to increase soundproof performance of houses(with glass wool)?

If you want to be simple, use sound barrier mats. If you want to be a completely soundproof environment, use sound absorption materials. If you use glass wool, you have to be aware of skin and respiratory tract infection.

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:Why is glass wool board used in portable house on the construction site?

Could it be that it is for fireproofing and prevention of burglary.

Q:How to use glass wool for filtering?

you can use buchner funnel or filter paper, specific question needs precious analysis, it mainly depends on the filter state, if solid particles are large, you can directly use ordinary funnel but not filter paper, when solid particles are small, you can use filter paper.
