Question:

Which is the more commonly used thermal insulation material between thermal insulation glass?silk wool and rock wool?

Answer:

Glass wool is a little better in that it has a lighter volume-weight than rock wool and better water-resistance ability, but it is more expensive than rock wool a lot of density, waterproof performance is better than lighter than wool to wool, but glass wool is more expensive in price per unit. In terms of fireproof effect, rock wool is definitely superior to glass wool. Rock wool has a maximum temperature of 1100 ℃, whereas glass wool has only 600 ℃. In addition, if used in the external walls, since glass wool has a limited volume-weight, which can merely reach at 60 to 90 in general, but rock wool have a volume-weight up to 140, so present-day external walls will not employ glass wool in general. Instead, rock wool is usually available because it is a A-level fireproof material. Glass wool is slightly lower than roock wool in thermal conductivity, while rock wool has longer fiber length. As for prices, glass wool per ton is more expensive than rock wool, but if the price is measured by per square, glass wool then is cheaper than rock wool.
Glass wool: Glass wool has no shots, having less dust and little irritation to skin and respiratory system as well as light weight, able to be processed to products with long length based on design requirements. It entails less waste, easy to construction. It uses amorphous cellulose which is soft and lathy with no shots, able to serve for more than 20 years. So, in terms of price per ton, rock wool is cheaper than glass wool. But in terms of price per square meter, the prices of glass wool and rock wool are basically flat. If various factors like effect, construciton, service life, safety and bearing structure are took into account comprehensively, glass wool then is more economical. Rock wool: It contains a high content of shots and much dust. It is high irritable to skin and respiratory system, keeping heavy weight, so it cannot be processed for a long time. It entails much waste, difficult to construction. It uses crystalline fiber, which has a high content of shots, is shoyt and unstable. If used for a certain time, its shots and short?fiber will sink, making it unable to maintain a uniform shape, which will seriously affect the insulation effect and needs to be replaced consequently. And the replacement cycle is shorter than 10 years.
