Can soundproof windows really be soundproof, and are soundproof doors and windows useful

Acoustic glassIt can play a soundproof effect.

Acoustic glass is a kind of glass product that has a certain shielding effect on sound, usually laminated glass with a double or multi-layer composite structure.

The sound insulation damping adhesive (film) in the middle of the laminated glass plays a key role in the weakening and attenuation of sound propagation, and the glass products with sound insulation function include laminated glass.

Classification of soundproof glass

1. Insulating glass

Insulating glass is two layers of glass with an air layer in between. When sound is transmitted from the air to the glass, it is reflected many times, thus playing the role of sound insulation and noise reduction. Insulating glass can reduce high-frequency noise very well, but the sound insulation effect of low-frequency noise is not obvious, and the sound insulation effect of insulating glass will be relatively poor.

2. Vacuum glass

Vacuum glass is almost pumped into a vacuum state in the middle of two layers of glass, and sound cannot be transmitted in a vacuum state, so vacuum glass can play a good sound insulation effect. In general, the sound insulation of vacuum glass can reach 39 decibels.

3. Laminated glass

Laminated glass is two or more layers of glass pressed together, with a soundproof film sandwiched between the glass.

When sound travels from the air to the glass, the membrane reacts to the medium waves.

Long-wave noise is absorbed and weakened, so it can play a role in sound insulation and noise reduction. The sound insulation effect of laminated glass is good, the sound insulation of ordinary laminated glass can reach 28-34 decibels, and the sound insulation of good laminated glass can reach 35-40 decibels.

Soundproof windows can indeed be soundproofed like dev soundproof windows can reach more than 42 decibels, basically closed windows are not able to hear the sound of people talking, for traffic noise and various complex noise, its sound insulation effect is also very good, widely used in airports, stations and high-speed rail along the residential soundproof use.

The soundproof window you are talking about is glass, or is it just a soundproof baffle in the position of the glass, if you are like soundproofing, or we recommend doing car soundproofing, like the ruling version, the new cotton, this kind of professional this.

Of course, it is useful, soundproof doors and windows are strict in the selection of profiles, glass, and sealing strips, and their sound insulation effect is very good, and the principle is as follows:

The materials and processes of soundproof doors and windows are different from ordinary double-layer glass, the processing method of this special door and window is made of carbon aluminum alloy and plastic steel as raw materials, through cutting, welding and other processes, and then attached to sealing, sealing, and tempered glass, steel or wood panels, asbestos boards and other accessories with sound insulation effect, sometimes adding a certain amount of steel bars to increase toughness and firmness, so that the doors and windows have the unique function of sound insulation.

To sum up, choosing a good soundproof door and window can effectively control noise.

Urban housing is becoming more and more dense, the population is also increasing, and noise is everywhere, so the installation of soundproof doors and windows has become an important requirement for urban citizens. Noise isolation is not only very beneficial for our health, but it is also essential for improving our quality of life. So in the face of all kinds of soundproof doors and windows on the market, what is their effect, and will the installation have the desired effect?

Next, let's learn about the advantages of soundproof doors and windows.

2. Do soundproof doors and windows work--reduce heat conduction.

First of all, soundproof doors and windows can reduce the conduction of heat, and its thermal conductivity coefficient is much lower than that of ordinary aluminum alloy doors and windows usually used, which can very effectively reduce the conduction heat from metal doors and windows. We all know that the summer temperature in the city is one or two degrees warmer than in the suburbs, and the application of soundproof doors and windows can avoid this problem, allowing us to spend a cool summer day easily.

3. Do soundproof doors and windows work--protect the environment.

Secondly, soundproof doors and windows can protect the environment, the current environmental problems are diverse, the society has been committed to solving environmental problems, noise pollution, radiation pollution has also been the focus of everyone's attention, soundproof doors and windows are a good choice to solve these two kinds of pollution. As mentioned above, it can reduce the conduction of heat, so that the heat in the house can be reduced to the outside world, thereby reducing the consumption of energy, which also reduces the use of heating and air conditioning, which can not only be warm in winter and cool in summer, but also effectively reduce the environmental radiation brought by it, killing multiple birds with one stone, and skillfully protecting the environment.

4. Do soundproof doors and windows work?

The most important and core advantage is the sound insulation effect of soundproof doors and windows. By reducing the resonance effect of sound waves, it prevents the transmission of sound waves, thereby reducing the decibels and playing a sound insulation effect. Experts point out that if people live in a noisy environment, their hearing will be directly damaged, declining day by day, and it will take hours or even tens of hours to recover, but if they are exposed to such noise for a long time, it is easy to cause hearing fatigue and even irreversible hearing diseases such as tinnitus, deafness and hearing loss.

The most direct benefit of sound insulation is that it is beneficial to people's hearing health, reducing ear diseases caused by high decibel noise, and indirectly, sound insulation can make people happy physically and mentally, avoiding irritability and pain caused by noise.

Soundproof doors and windows are made of plastic steel, aluminum alloy, carbon steel, and cold steel plate building hardware materials, extruded into the material, and then made into door and window frame sashes by cutting, welding or screwing, and equipped with sealing strips, wool strips, hardware, glass, PU, cotton absorption, wood plates, steel plates, asbestos plates, galvanized iron sheets and other environmentally friendly sound-absorbing and sound-insulating materials, etc., at the same time, in order to enhance the rigidity of the profile, more than a certain length of the profile cavity needs to be filled with steel lining (stiffeners), so that the doors and windows made are called soundproof doors and windows. For different noise sources, the system considers all the factors that affect the sound insulation effect, and selects different profiles (combined with special processes, fully considering the needs of different users.

Yes, soundproof curtains are very different from regular curtains. The first is the weight, which is much heavier in comparison to soundproof curtains; The second is the material, the material of the soundproof curtains is almost all porous like waffles; Finally, the structure, the soundproof curtain is a multi-layer structure of absorption + partition, so as to further strengthen the sound insulation effect.

It is still very useful to create what we call low-frequency noise, especially for low-frequency noise, one is the sound of people talking, one is the noise of the engine, one is the noise of the engine and car tires, especially the tire noise, which is a very typical high-intensity low-frequency noise, the general aluminum alloy, plus insulating glass or broken bridge aluminum, plus insulating glass has no way to deal with this sound, only professional-grade soundproof glass, such as dev glass can deal with this sound.

Soundproof windows are of course useful, so that noise can be reduced, which means that the noise outside is relatively loud, and the noise is basically not particularly loud from the inside.

Soundproof windows are useful, it can isolate most of the sound, but compared to ordinary windows, ** will be relatively high, but if it is a necessity for you, it will not feel expensive.

The wall is not soundproof, even if the soundproof window is not good, the sound cannot only come in through the window, and the soundproof window will be quieter.

It has a certain effect, but if the noise is very loud, it cannot be completely covered.

Soundproof windows are still not useful, but you have to make sure that the sound comes from the window, you can start from the creation, then if it is from the wall or the floor, then you need to transform more things, it is better to directly complain to them, let them do things well, if you want to make soundproof windows, like the broken bridge aluminum insulating glass window is not enough, this can only isolate the general noise, like the sound of people talking and taking pictures of low-frequency noise, this is not isolated, This requires the use of professional-grade dev soundproof windows, but this kind of window is more expensive, and after you order from the manufacturer, the installation problems you may face are more realistic, because there are not necessarily their distributors in your city.

useful, can reduce the impact of external noise,

Soundproof windows are still very useful because they are made of several layers of material or glass, and a special soundproof layer is formed in the middle, so that the noise is effectively blocked out of the window. In addition, special materials are added to the processing of this type of window, and the accessories and window frames are also tightly edge-banded to make the sound insulation effect more prominent.

However, from the performance analysis, the soundproof window is not the thicker the material or glass layer, the better, that is, the number of multiple layers, once the number of layers is too much, it will naturally affect the sound insulation effect of the window. In the building materials market, it is not difficult to see that there are three layers of soundproof windows**, but the sound insulation effect of such products is not ideal. This is mainly because most of these soundproof windows use insulating glass, and if there is not enough density and sound insulation layer, it will eventually affect the sound insulation performance of the window.

A soundproof window can effectively insulate sound, but it is not completely soundproof. The soundproofing effect of a soundproof window depends on the tightness of the window and the quality of the soundproof glass.

Well-sealed soundproof windows can significantly increase the level of quietness in the room by reducing the incoming amount of outdoor noise, but at the same time reducing the amount of sound coming out of the room.

The quality of the soundproof glass is also a key factor affecting the effect of the soundproof window. High-quality soundproof glass can effectively reduce the transmission of noise, while ordinary clear glass does not. Spine Defeat.

In addition, the sound insulation effect of soundproof windows is also related to the quality of Sakurawang's installation. If the installation of soundproof windows is improperly prepared, such as aging window seals, poor glass installation, etc., the sound insulation effect of soundproof windows will be affected.

As a result, soundproof windows can significantly increase the level of quietness in a room, but they are not completely soundproofed. If you need a quieter indoor environment, it is recommended to take other soundproofing measures at the same time, such as installing soundproof curtains and adding soundproof walls.

separationThe sound window can be insulated, and the soundproof curtain can be completely isolated from the low-frequency sound of 8-12 decibels.

Soundproof windows are made of double-layered or three-layer, four-layer homogeneous texture, different thicknesses of glass and window frames, and the material is also specially made of processed soundproof layer after a series of processing, so that the window can achieve the effect of sound insulation of a kind of window.

Regular soundproof windows are basically less hollow and vacuum glass, but PVB laminated glass with better sound insulation effect, and its sound insulation effect is also recognized by the industry as very good.

Its PVB laminated glass has a very good sound insulation effect, which can use the different resonance frequencies of different media to eliminate the penetration of sound waves, effectively resist the noise, especially for repetitive road noise, which has incomparable advantages of other products.

How to choose the profile and glass of soundproof doors and windows?

1. Profile: plastic steel (the sound insulation effect is naturally better than other profiles) Broken bridge aluminum (the quality is good, there is a heat insulation effect, but the sound insulation effect is poor).

2. There are four main types of glass on the market: insulating glass, vacuum glass, insulating laminated glass, and laminated glass.

If it is clear that the demand is sound insulation, it is recommended to choose hollow laminated glass and laminated glass.

1. The first thing that should be explained is that soundproof windows cannot isolate noise. When there is a set sound insulation amount as a dust insulation product, it can only reduce the sound insulation amount of noise to an appropriate degree in terms of sound insulation. As a soundproof window, glass can reduce noise by about 25 decibels.

When laminated as a soundproof window, it can reduce the noise by about 35 decibels, and a soundproof glass can reduce the noise by about 45 decibels.

2. As for the effect, it depends on the size of the outdoor noise and the level of sound insulation performance of the soundproof window, for example, the indoor noise of a soundproof window user is less than 35 decibels in a very quiet environment, and even the sound absorption of people's voices can be heard really.

There will be windows installed in the house, but now there are many types of window materials, and the windows also have sound insulation effect, but we must have a certain purchase method when buying, because if the choice is not good, it will not be soundproof, thenSoundproof windowsHow? What are the precautions for choosing soundproof windows? If you want to know, let's take a look.

1. How about soundproof windows.

The soundproof window is composed of double-layer or three-layer glass of the same texture or glass of different thicknesses and window frames, using a specially processed soundproof layer, and the soundproof layer glass is made of PVB film firmly bonded by high temperature and high pressure; or between the sound insulation layers, an aluminum alloy partition filled with desiccant (molecular sieve) is sandwiched, and the edge is bonded with sealant (butyl glue, polysulfide glue, structural adhesive) to form a glass component; The other is to use the principle of thermos flask to make a transparent and light-free balanced and compression-resistant flat pin-type pin glass component. Effectively suppress the "anastomosis effect" and the formation of sound insulation valley, fill the window frame with sound-absorbing materials, fully absorb the sound waves of transparent glass, and isolate the noise of each frequency band to the greatest extent.

Second, the purchase method of soundproof windows.

1.The glass material of soundproof glass window is divided into ordinary glass, insulating glass, multi-layered insulating glass and vacuum glass, etc., the sound insulation effect of vacuum glass is the best among these glasses, because vacuum glass separates two pieces of glass, and pumps the air in the middle of the air, and forms a vacuum layer between the glasses, which is soundproof by the principle that sound cannot be transmitted in the vacuum;

2.Vacuum glass, 70-80% of the air is extracted between the two layers of glass, and 20-30% of the inert gas is left in the middle of the two layers of glass, and then the PVB rubber particles are padded in the middle of the two layers of glass to resist the two layers of glass, so that they do not adsorb together. If the plastic bottle draws air, it is soft and can be deformed and can be adsorbed together.

3.The types of windows include casement, sliding and fixed, in terms of sound insulation, fixed windows have the best sound insulation, but this kind of windows are only suitable for places that do not need to be opened but have lighting needs; Compared with casement windows and sliding windows, the sound insulation effect of casement windows is better than that of sliding windows, and owners can choose the right type of windows according to their needs.

4.Some owners want to save money to buy soundproof windows in some small shops, but if they find that the quality of the windows is problematic afterwards, most of the owners can not find the merchant to compensate, if the owner buys in a regular home store, even if the store that buys something can not be found, the store will also solve the problem of the lack of respect for the owners, so that it is easier to protect their rights and interests.

Our windows generally choose to install sound insulation effects, so how to buy soundproof windows and what are the precautions for its loss, I want to see the above introduction, everyone also understands these.
