Q:There is an engineering air-condition air duct which uses aluminum foil glass wool for heat conservation, supervor require that it should be added a protective layer made by glass fiber cloth. according to peremptory norms,

1, this problem is mainly depending on the contract you signed with the above 2, there is no clear guideline, if the owners is rich, you can coat moisture-proof layer containing sackcloth material and two layers of 25mm thick plaster protective layers on the 70mm bulk fiber heat conservation layer outside the air duct, and coat the outer edge with two layers of aluminium paint.

Q:Does rock wool board refer to the glass wool ?

same properities, glass wool belongs to glass fiber, and rock wool, rock and mineral raw materials such as short and thin fiber in fluffy shape.

Q:Centrifugal glass wool board and flexible foam rubber insulation, which one is better?

Glass wool board has good fireproof performance and can endure higher temperature than the rubber material, which is cheap. Rubber material has poor fireproof performance. It has insulation performace no better than other materials.

Q:what is the raw materials producing glass wool insulation materials?

simply put. It is a kind of glass, just like using white sugar to make cotton candy.

Q:How about the sound insulation performance of glass wool felts?

Fix the glass wool in the wall with pegs, then cover it with plywood, after laying up with wooden surface, nail the wood again.

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: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:The main classification and difference of glass wool

And then by the temperature curing furnace, complete the curing process, product stereotypes, after cutting through the stereotypes will become a predetermined product, and then packaging.

Q:How to install sound insulation glass wool boards on the wall?

First set up the keel into the shape of a lattice, and put the glass wool board into the lattice and install the gypsum board.

Q:These two kinds of glass wool are used as insulation materials, but one keeps 0.3 in specific gravity while the other keeps 0.5 in specific gravity. Which one should be chosen?

Specific gravity has much to do with quality and thermal conductivity.
