Q:What are the advantages and disadvantages of centrifugal glass wool?

Centrifugal glass wool board is fiber product, so human body will be allergic, whose temperature endurance is 400 degrees with good thermal insulation effect, mainly used in buildings and underground pipes.

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

Is it used on car?

Q:During the construction of steel structure, should the aluminum foil of glass wool be directed indoors or outdoors? Why?

The aluminum foil of glass wool should point toward the indoor.

Q:what's the temperature the high temperature glass wool endure?

400 degrees

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

Low density than glass wool rock wool, low shot content, low thermal conductivity, long service life, high tenacity fiber, rock wool, but the maximum use of high temperature up to about 600 degrees Celsius, the glass wool is only about 260 degrees Celsius. Glass wool and rock wool insulation board insulation board product differ in their application . The former one is used in areas where the temperature is below 200 degrees Celsius, such as general buildings and low-temperature pipes while the latter one is used in areas where the temperature is 500 degree Celsius, such as high temperature thermal pipe or eletrical equipments insualtion.

Q:Which one is more enviroment friendly, glass wool mat or rock wool sound insulating block?

Neither of them is environment friendly and they all have dust.Polyester cotton is much better in terms of environmental protection.

Q:What are the requirements for filling the glass wool insulation materials?

It depends on design requirements, local climate and budget.

Q:What are the hardnesses of rock wool and glass wool respectively? Are there any requirements on saw blade?

I do not know about the hardness, but I know that ordinary hacksaw is enough. I'm sorry, I don't have calculation parameters.

Q:Are thermal insulation glass?wool?boards hydrophobic?

Do not believe any hydrophobic agents. Products being processed with silicone hydrophobic agents have a short hydrophobic phase, and the performan of which has no guarantee. The thermal insulation performance of A-level glass wool products are poor which may lead to inferior wallboard engineerings.

Q:What are the functions of the thermal insulation glass wool board?

Glass wool insulation materials are medium and low temperature thermal insulation materials, thus they are generally used in civil and cryogenic pipeline with the temperature of -120 ℃ -400 ℃. They can be used for thermal insulation and sound absorptionin in fields of construction, petrochemical, electric power and metallurgy.
