What is the difference between soundproof glass and ordinary glass?

The biggest difference between soundproof glass and ordinary glass is the ability to reduce noise.

The difference between soundproof glass and ordinary glass - soundproof glass.

Soundproof glass is a kind of glass products that play a certain role in shielding sound, usually laminated glass with double-layer or multi-layer composite structure, and the soundproof damping glue (film) in the middle of the laminated glass plays a key role in the weakening and attenuation of sound transmission, and glass products with sound insulation function include laminated glass. Compared with ordinary glass, when various outdoor sound sources vibrate and produce noise, the noise is transmitted through the air medium, when the noise is transmitted to the soundproof glass doors and windows, and then attenuated by the soundproof glass one by one, especially when the noise passes through the soundproof damping glue, the medium frequency noise and high-frequency noise are absorbed, twisted, shocked and attenuated by the soundproof damping glue, which can effectively filter out the medium and high frequency noise, and finally enter the indoor noise is only about 5%.

Second, the difference between soundproof glass and ordinary glass - ordinary glass.

Ordinary glass is a single-layer structure, which is a layer of glass from the inside out.

3. The difference between soundproof glass and ordinary glass.

The difference between the isolation glass wall and the ordinary glass wall on the market lies in the glass panel, and the sealing material and method of aluminum profile between the glass. According to the middle part of the soundproof glass wall, it can be divided into four categories, namely: insulating glass, vacuum glass, laminated glass and double-layer structural glass.

Modern offices, especially some large office buildings, will use glass walls instead of solid walls for the sake of style uniformity. This design can make the whole building taller and better, and can improve the image of the tenant company. But there are two problems, one is privacy, and the other is sound insulation.

The differences between acoustic glass and acoustic membrane are as follows:

Soundproof glass is a kind of glass products that play a certain role in shielding sound, usually laminated glass with double-layer or multi-layer composite structure, and the glass film (interlayer) in the middle of the laminated glass plays a key role in the weakening of sound transmission, and glass products with sound insulation function include laminated glass.

Acoustic glass film is a polyester film attached to the surface of glass, which has the effect of changing the properties of glass. It is based on polyester substrate (PET) (full name is polyethylene terephthalate ethylene terephthalate) as the base layer, which is a material with strong durability, strong strength, high toughness, moisture resistance and low temperature performance. It is clear and transparent, and the composite film is formed after a variety of complex processes such as body dyeing, polymer particle layer, metallization coating, magnetron sputtering, sandwich synthesis, etc., one side is coated with an anti-scratch layer, and the other side is the installation of adhesive layer and protective film, and the soundproof glass film can play a role in sound insulation, heat insulation, explosion-proof, and ultraviolet protection.

Ordinary glass is what we usually call this kind of glass, such as insulating glass, tempered glass, laminated glass, these are ordinary glass, then soundproof glass is actually glass with sound insulation function, such as PVB laminated glass, such as three-glass two-cavity insulating glass are all types of soundproof glass, professional-grade soundproof glass, such as DEV soundproof glass, and NM combined soundproof glass and so on.

The difference between soundproof glass and ordinary glass is still very huge, soundproof glass is generally the use of deva soundproof damping film, after pressure processing, and ordinary glass is hollow structure or laminated structure, heavy sound insulation effect, dev soundproof glass sound insulation effect is very good, and insulating glass can only be isolated, part of the high frequency noise is completely ineffective for low-frequency noise, and the laminated is mainly used for safety purposes, sound insulation has a certain effect, but it is not obvious, Therefore, soundproof glass is a professional-grade glass, and the difference between ordinary glass is very huge.

Glass sound insulation is mainly because the density of glass is relatively large, when the sound penetrates the glass, there will be a certain degree of reduction and attenuation, as well as refraction phenomenon, and at the same time, when the sound propagates on the surface of the glass, it will make the glass produce a certain vibration, and it will also weaken a certain amount of sound wave energy, so the glass will be sound insulation.

At the same time, some new types of soundproof glass adopt some new technologies, such as DEV glass is processed with Deva soundproof damping film, and its sound insulation volume can be as high as more than 40 decibels.

Glass performance characteristics:

It is divided into: tempered glass, porous glass (i.e., foam glass, with a pore size of about 40nm, used for seawater desalination, virus filtration, etc.), conductive glass (used as electrodes and aircraft windshields), glass-ceramic, opalescent glass (used for lighting devices and decorative items, etc.) and insulating glass (used as door and window glass), etc.

The molecular arrangement of glass is irregular, and its molecules are statistically homogeneous in space. Ideally, the physical and chemical properties of homogeneous glass (such as refractive index, hardness, modulus of elasticity, coefficient of thermal expansion, thermal conductivity, electrical conductivity, etc.) are the same in all directions.

Because glass is a mixture, amorphous, there is no fixed melting boiling point. The transformation of glass from a solid to a liquid takes place within a certain temperature region (i.e., the softening temperature range) and, unlike crystalline substances, does not have a fixed melting point.

Soundproofing. Specialized soundproof glass is soundproofing.

Soundproof glass is a kind of glass products that play a certain role in shielding sound, usually laminated glass with double-layer or multi-layer composite structure, and the soundproof damping glue (film) in the middle of the laminated glass plays a key role in the weakening and attenuation of sound transmission, and glass products with sound insulation function include laminated glass.

The principle of sound insulation effect produced by sound insulation glass: various outdoor sound sources produce vibration noise, noise is transmitted through air medium, when the noise is transmitted to the sound insulation glass doors and windows, and then attenuated by the sound insulation glass one by one, especially when the noise passes through the sound insulation damping glue, the medium frequency noise and low frequency noise are absorbed, twisted, shock absorbed, and attenuated by the sound insulation damping glue, which can effectively filter out the medium and low frequency noise, and finally enter the indoor noise only about 5%.

Key points for the purchase of soundproof glass:

1. The size of the area of the soundproof glass: the larger the area of the window glass, the more sound through the window glass. The larger the window, the more difficult it is to insulate the sound, and under the same conditions, the smaller the window area, the better the sound insulation, and the quieter the room.

2. The distance between the soundproof glass and the sound source: the farther the window is from the noise source, the greater the noise level is reduced, and the faster and easier the noise attenuation. High-frequency noise decays rapidly with distance or obstacles, dropping by 6 decibels every 10 meters.

Low-frequency noise is very penetrating, decreasing very slowly, and the sound waves are long, which can easily pass through obstacles, run long distances, and penetrate walls and walls into the human ear.

3. The height of the floor: the higher the floor height, the more medium and high frequency sounds, and the easier it is to insulate and reduce noise.

Look at the outside world through doors and windows every day, but do you know the special features of the glass on doors and windows? Palaide soundproof doors and windows, here"Glass"Redefined, it's beyond your imagination! Glass is one of the important components of doors and windows, good doors and windows are inseparable from good glass, and good home environment and safety are inseparable from good doors and windows.

So what types of high-end doors and windows can be selected when choosing glass? What do they do?

Insulating glass. Insulating glass is a composite of two or even three layers of glass to change the propagation medium of sound waves, so that the energy of sound waves can be consumed, so as to achieve sound reduction, effectively block the entry of external sound, and achieve the purpose of sound insulation and noise reduction. In general, the thermal conductivity of the sealed middle air layer is much lower than that of normal glass, so the thermal insulation performance of insulating glass can be increased by a factor of two compared to monolithic glass. The glass design is optimized to achieve a super sound insulation effect, the hollow tempered glass is made of a combination of glass of different thicknesses, with inert gas, a large width of the hollow layer, a double sealant, and no resonance in the noise environment, making the space sound insulation experience excellent.

PVB laminated glass.

Laminated glass, also known as laminated glass, is made of two or several pieces of float glass sandwiched with a strong PVB adhesive film, which is pressed by a hot press at high temperature and high pressure. The addition of PVB film can change the propagation medium of sound waves, so that the energy of sound waves can be consumed, so as to achieve sound reduction and effectively block the entry of external sounds. Laminated glass is characterized by its multi-functional functions such as safety, heat insulation, ultraviolet protection, explosion resistance, and sound insulation.

Moreover, it can be widely used in building door and window glass, light shed, overhead ground, high-grade curtain wall doors and windows, furniture, aquariums, etc. Today, when product safety is becoming more and more important, it is widely used in high-end doors and windows, and is also loved by high-end residential and villa users.

Coated glass. Coated glass, also known as reflective glass, coated glass is coated with one or more layers of metal, alloy or metal compound film on the surface of the glass to change the optical properties of the glass to meet a specific requirement. According to the different characteristics of the product, coated glass can be divided into the following categories: heat reflection glass, low-e glass (low-e) It is mainly used in glass curtain walls, building doors and windows, automobiles, ships, etc.

Always be careful, sincere, confident, patient, persevering, and assured"Six hearts"For the service concept, to bring consumers more intelligent, more comfortable and more aesthetic door and window products. The doors and windows are made of insulating glass, which has strong functionality, which greatly improves the heat and sound insulation performance of doors and windows, just to bring you a better living experience, choose Palid doors and windows, and choose a high-quality living lifestyle.

Glass sound insulation is mainly because the density of glass is relatively large, when the sound penetrates the glass, there will be a certain degree of reduction and attenuation, as well as refraction phenomenon, at the same time, when the sound propagates on the surface of the glass, it will make the glass produce a certain vibration, and will also weaken a certain sound wave energy, so the glass will be sound insulation, at the same time, some new types of sound insulation glass use some new technologies, such as deva glass is processed with deva sound insulation damping film, and its sound insulation can be as high as more than 40 decibels.

The reason why the soundproof glass is soundproof is mainly because the resonance coefficient between the glass is adjusted, and there is a layer of deva soundproof damping film between the glass and the glass, the function of this soundproof damping film is to absorb the vibration of sound waves and reduce the transmission of sound waves, so for soundproof glass, the glass production and sound insulation are formed by the superposition of these two aspects, and the direct consequences of this resonance and noise-absorbing structure.

The sound insulation effect of ordinary glass is mainly because it slows down the sound propagation, because the sound must have a medium to propagate, and the vacuum cannot transmit, and the speed of sound propagation is gaseous liquid and solid respectively, and ordinary glass is solid, which can prevent the propagation of part of the sound wave and block the sound wave out of the glass. The soundproof glass is to use the characteristic that sound cannot be transmitted in a vacuum, and artificially create a vacuum space, that is, the soundproof glass is two-layered, and a layer of vacuum is separated between the two layers of glass, which prevents the transmission of sound. The more vacuumed this vacuum layer is, the better the sound insulation.
