Is it effective to put a soundproof cotton seal calcium silicate board on the wall?

It can be isolated from indoor noise, outdoor by the window, and the sound insulation effect of the aluminum alloy bottom with a broken bridge is very good** more expensive.

Calcium silicate board ceiling, with natural gypsum as raw material, the product is called "calcium silicate board", or embossed gypsum board. It is a porous material with good sound and heat insulation properties, which can attract water molecules in the air when the indoor air is humid, and can release water molecules when the air is dry, which can properly adjust the indoor dryness, humidity and increase comfort. Gypsum products are also special fireproof materials, which can produce endothermic reactions in the flame, and at the same time, release water molecules to prevent the spread of fire, and will not decompose to produce any toxic, corrosive, suffocating gases, nor will they produce any combustibles or smoke.

Compared with gypsum board, calcium silicate board retains the beauty of gypsum board in appearance; In terms of weight, it is much lower than that of gypsum on paper, and much higher in strength than gypsum board; It has changed the Achilles heel of gypsum board deformation due to moisture, and extended the service life of the material several times; In terms of functions such as sound suppression and thermal insulation, it is also improved compared with gypsum board. It is also better than mineral wool board and gypsum board in terms of fire protection.

Calcium silicate board is reinforced with asbestos, the sound insulation effect is not very good, the reason is that the ceiling can not be really sealed, and there are gaps at the edge of each piece.

Mineral wool board with mineral wool as the main raw material, loose structure, poor deformation resistance, after a period of use, there will be different degrees of deflection deformation, yellowing, heavy bearing strength is low, will not exceed 5 kg. The mineral wool board is made of high-quality slag as raw material, refined into a spherical sponge, organic fibers and inorganic fibers are used together, and the combination of moisture-proof agent and auxiliary moisture-proof agent is used to use the new concept of moisture-proof supplemented by prevention and control, so as to achieve moisture-proof and waterproof, this moisture-proof technology can only be maintained for a period of time.

The full name of calcium silicate board is fiber reinforced calcium silicate board, which is made of siliceous materials (diatomaceous earth, bentonite, quartz powder, etc.), calcareous materials (cement, lime), reinforced fibers, etc. as the main raw materials, and is made of pulping, billeting, steaming, surface sanding and other processes. It belongs to the second generation of gypsum interior decoration materials.

It is recommended to use calcium silicate board and mineral wool board compared with mineral wool boardHigh crystalline plates(The upgraded version of calcium silicate board), the main components of high-crystal board are natural gypsum and gypsum modified admixtures, silicone waterproof admixtures, modified ingredients, glass fiber, etc. The strength has been greatly improved, and the waterproof and moisture-proof performance is excellent. High-crystal ceiling is a new type of ceiling material, with fire retardant, water and moisture-proof, light weight and high strength, green environmental protection, convenient decoration and long-term discoloration and other excellent performance, various styles can meet various design requirements, and can produce high-grade decorative effects.

Calcium silicate board: generally composed of natural gypsum powder, white cement, glue and glass fiber.

Mineral wool board: the biggest advantage is good sound absorption effect, outstanding fire performance, and small quality.

The sound insulation and warmth insulation performance of calcium silicate board is not ideal, it is easy to change and turn yellow when wet, and the hardness is low.

Calcium silicate board has high hardness, good sound insulation and warmth performance, and it is not easy to replace it after installation, and it is necessary to use an iron keel during installation, which is more expensive.

Mineral wool board is one of the largest ceiling materials used in the world. The texture is light, and the specific gravity is only. There are also functions of sound reduction, sound absorption, and noise reduction.

It is suitable for office, hospital, education and other occasions. Calcium silicate board is gypsum board, the main ingredient is calcium sulfate dihydrate, the weight is large, the specific gravity is about about, at present, some add light fillers and improvers, etc., the sound insulation effect is good, it is used for the ceiling is too heavy, not conducive to safety, and is generally used for partition walls.

Calcium silicate board is a dense type board, which is basically impermeable. Heavier and stiffer than acoustic panels. It is a sealing type sheet. It mainly plays the role of sound insulation. That is, to block the propagation of sound in the space on both sides of the plate.

The sound-absorbing panels are porous and jointed, which are basically breathable. Most of them can see directly through the plate to the naked eye, and see things on the other side of the board. It mainly plays the role of sound absorption, that is, to reduce the reflection of a certain frequency on one side of the plate.

There are very few sound-absorbing panels that directly do partitions, so sound-absorbing panels are generally not used to deal with the sound problem of the space on both sides of the board, but only to deal with the one-sided sound field.

Calcium silicate board is a lightweight board made of siliceous materials, calcareous materials, reinforcing fibers, etc., which are made of pulping, billeting, steaming, surface sanding and other processes. It is a kind of hard board, which is similar to gypsum board, which has no sound-absorbing function and mainly plays a decorative effect.

Acoustic panel ceilings, also known as mineral wool boards, are made of mineral wool, mineral fibers, perlite, starch and other renewable green materials. It has efficient sound absorption ability, which not only plays a decorative role in the ceiling, but also has sound absorption and thermal insulation effects.

**Calcium silicate board is cheaper, and the common mineral wool board brands on the market are Armstrong and Meiluda brands, which are better in the sound-absorbing board.

The effect of the red brick wall is still OK, but it should be fast and convenient, sound insulation and noise reduction, and moisture-proof, it is recommended to make the following structural wall: calcium silicate board + gypsum board + keel + gypsum board + calcium silicate board, here pay attention to the structural order. Staggered installation, you can add some glass sound-absorbing cotton in the middle.

After the completion of the wall flour batch and the footing, such an effect insertion loss can reach more than 45db. Also, the thickness of the plate should not be lower.

If you want a detailed answer, you can call me or send me a message.

If you are also using it for your own home renovation, I recommend you to use Saint-Gobain Jacco's Red Jacco plasterboard.

The following is the official introduction of their Red Jack gypsum board products::

My house was just renovated last year, and I used Hongjieke, which can be used as both a ceiling and a partition wall, and the functionality is also very powerful. Gypsum board itself is an environmentally friendly product, does not release any toxic and harmful radioactive substances, and the overall effect in the room is very comfortable.

Use calcium silicate board to make light steel keel partition wall The wall is filled with sound-absorbing cotton Calcium silicate board is different from gypsum board He has a high hardness (you also want to be harder, you can add barbed wire to improve the load-bearing) High density and good moisture resistance Sound-absorbing cotton plus foam board can meet the requirements of the brick wall If you want to hang the TV, you need to use a large core board to reinforce the position of the scrape TV on it, there are a lot of new materials you have to go to the market to understand.

It is a dense type plate and is basically impermeable. Relatively heavier and stiffer. It is a sealing type sheet. It mainly plays the role of sound insulation. That is, to block the propagation of sound in the space on both sides of the plate.

It is a porous and seam board, which is basically breathable. Most of them can see directly through the plate to the naked eye, and see things on the other side of the board. It mainly plays the role of sound absorption, that is, to reduce the reflection of a certain frequency on one side of the plate.

It is rare to do partitions directly, so the acoustic panels are generally not used to deal with the sound problem of the space on both sides of the board, and only deal with the one-sided sound field. (Ferroalloy spot network) to provide you with the answer i

Dear, in fact, it depends on where you use it, and the same material plays a different role in different places.
