Q:Whether the combustion performance of glass wool blanket can reach A grade

Glass wool and rock wool are commonly grouped into the category of A grade fireproof material .

Q:What are the differences among glass wool, rock wool and mineral wool?

Glass wool is usually used in the industrial field, that is glass?silk. Rock wool is generally used in external thermal insulation of pipelines, and in the sound insulation of partitions or the thermal insulation of ceilings. You must know about mineral?wool?boards, generally, they are used in office as suspended ceilings. The main function of which is sound absorption. If you want thermal insulation and sound absorption, you can use them both, haha.

Q:Which has better effect of thermal insulation, glass wool or rock wool ?

They are basically the same, but glass wool is more eco-friendly, with smaller loss.

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

It depends on design requirements, local climate and budget.

Q:How to conduct thermal insulation construction of external wall glass wool?

The construction period of insulation consrtuction of this project takes 20 days, which is a tight schedule, so the insulation construction should be organized properly to ensure the insulation construction period. The insulation construction of Dingfuzhuang secondary school needs to undergo the following process: firstly conduct construction of external wall insulation of teaching building; secondly conduct construction of external wall insulation of laboratory building and finally conduct construction of external wall insulation of cafeteria. Scaffolds of the outer edge of the teaching building have been fully completed, so the four facades of the teaching building can be constructed simultaneously in a bottom-up way. When shotcrete construction of the outer edge of laboratory building finished, it then can conduct insulation construciton of the outer edge of laboratory building. At this time, thermal insulation construction of teaching building have not fully completed, which requires supplement labor force to ensure thermal insulation construction of these two buildings to be conducted simultaneously. When the outer edge of cafeteria is qualified for thermal insulation construction, it needs to supplement labor force for thermal insulation construction, so that these three building can conduct thermal insulation construction simulanteously.

Q:Which is more effective in retarding fire, rock wool or glass?wool? What is the difference between rock wool and glass wool?

In terms of fireproof effect, rock wool is certainly better than glass wool. The maximum temperature of rockwool is 1100 ℃, and glass wool is only 600 ℃. In addition if used in the external walls, the highest unit weight of glass wool can only be in the range of 60-90, but rock wool can be over 140. Generally glass wool can not be used in external wall at present. Only rock wool is A grade fireproof material.The heat conductivity coefficient of glass wool is lower than glass wool and the fibre length of rock wool is longer than glass wool. As for price, tons of glass wool rock is more expensive than that of rock wool. However, if counted by square size, glass wool is cheaper per square size than rock wool.

Q:What is glass wool board.

Glass wool is fibrillation by the fusion of the glass, adding binder to solidify the material to make the glass wool roll mat, while the glass wool fibre?diameter is contracted by the centrifugation. The difference is in the centrifugation techniques. the centrifugation techniques currently used most frequent is Saint-Gobain's Isover TEL centrifugation technique, which is the originator of glass wool products. At present the domestic glass wool market is gradually expanding, and enterprise Dacheng Quanhe Chemical Co., Ltd. makes a significant contribution to promote the use of glass wool.

Q:Is centrifugal glass wool board suitable for home use?

A large number of people think that glass wool boards are harmful and that it will cause itch when contacting with the skin. And the effect is not obvious used in the surface, so it is generally used in the wall sandwich. They are harmless for wool boards have been checked, and only those which have passed the national inspection are allowed to be sold for home use. But do not use it in the surface as it is fiber products.

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

Low cost

Q:Is the centrifugal glass wool board suitable for home use?

Glass wool contact with the skin will be a little itch
