Broken Bridge aluminum doors and windows is now the mainstream door and window materials. Some owners of broken bridge aluminum window glass are not very clear. Today, I will analyze and interpret some misunderstandings of window glass to let everyone understand the importance and particularity of glass.
Broken Bridge aluminum several misunderstandings of window glass:
Misunderstanding 1. Hollow glass is mistaken for vacuum glass: this is the biggest mistake in the Broken Bridge aluminum window glass market. Many consumers who don't understand often think that the window glass is vacuum glass and that there is no air, in fact, broken bridge aluminum of the window glass on the market is equipped with hollow glass, that is, double-layer glass, and there is an air layer between the two layers of glass. Hollow glass is not vacuum glass. The concepts of the two are different. Hollow glass uses two (or three) pieces of glass and uses high-strength and high-air-tightness composite binder to bond glass Cover with aluminum alloy frame containing desiccant, made of high-efficiency sound insulation glass. Hollow glass is not a professional sound insulation glass. Although it is effective for voice, it does not have a particularly good sound insulation effect for other medium and low frequency noise such as traffic noise. However, for the living environment with low noise, it is enough to use insulating glass for sound insulation.
Misunderstanding 2. Three-layer hollow glass is better than double-layer glass in sound insulation: this is also a misunderstanding in the Broken Bridge aluminum glass market. There is no big difference between the three-layer hollow glass and the double-layer glass in the sound insulation effect. On the contrary, the hollow glass has a better sound insulation effect than the Triplex glass glass, however, in terms of heat preservation effect, the three-layer hollow glass is definitely better than the double-layer hollow thermal insulation effect. For this conclusion, many owners have doubts about why an extra layer of glass has been added, but the sound insulation effect is not very ideal? We have a detailed interpretation of this article "common doors and windows glass sound insulation secret: Triplex glass Non-sound insulation.
Hollow glass is also a part of broken bridge aluminum doors and windows. After the aluminum alloy profile is disconnected, the glass used becomes hollow glass. Hollow glass can be two layers of glass or Triplex glass. High-performance sound insulation glass is made by using high-strength and high-air-tightness composite binder to bond glass Cover with aluminum alloy frame containing desiccant.
Misunderstanding 3. Ordinary glass is OK, there is no need to tempered: At present, the glass of broken bridge aluminum windows is standard ordinary hollow glass. If you want to upgrade tempered glass and so on, you need to add extra money. Is it necessary to tempered glass? If there are many French windows in your home, a single piece of glass is not particularly large, you can use ordinary hollow glass, there is no need to tempered; If the window is a French window, the lower part must be tempered, A single piece of glass larger than 1.5 square meters must also be tempered. If your home is a high-rise building, it is better to choose tempered glass, which is safer.
But to say that sound insulation and heat insulation must be three layers of good, but the weight of tempered glass is not light, and the additional layer virtually increases the bearing capacity of hardware such as folding. I have asked people who make glass that the metal has toughness and will be fine for one or two years, but no matter how good the hardware is, it will be deformed after carrying heavy glass for a long time.
Moreover, there is one more layer of glass, and the price is also the highest. After all, building materials are used more. But in terms of performance, double-layer glass is already very good, and it costs a lot of money to buy Triplex glass, which is really not necessary.
First: tempered glass has the highest safety factor.
If both indoor and outdoor glass are made of tempered glass, the impact resistance and safety of glass are the best, because tempered glass is not only 5-10 times that of ordinary glass in impact resistance, moreover, the glass will not cause secondary damage when broken, which is very safe! Laminated glass is also a kind of tempered glass. In most cases, laminated glass is used to build the top of the sun room or other places that require better safety.
Second: Hollow tempered glass with sound insulation, heat insulation and energy saving
Hollow tempered glass seals the air between the glass and greatly enhances the sound insulation performance of the glass and has strong heat insulation performance. Compared with ordinary monolithic glass, hollow tempered glass can reduce the noise by about 21 decibels, reducing heat transmission by more than 40% can play the role of indoor insulation, warm in winter and cool in summer! At the same time, choosing hollow double tempered glass has a certain safety. The combination of function and safety is the best choice in terms of sex price.
Third: room window Chaoyang can use low-e coated glass
Friends in the South should know that the weather in summer is very hot, with an average temperature of 30 degrees to 39 degrees, so the glass is exposed to the strong sunlight for a long time, not to mention how hot and dazzling it is, the strong ultraviolet radiation is also very harmful to the body, just because the high temperature is unbearable. Therefore, in Chaoyang rooms, window glass can choose low-e coated glass, which can play the role of heat insulation and radiation protection. It belongs to a kind of green and energy-saving glass!
Broken Bridge aluminum doors and windows glass selection
Fourth: increase the safety factor of special multi-layer composite hollow glass
Because there are metal wires or silk screens in the middle of the laminated glass as supporting frames, it has certain safety fire resistance and is mainly used for inlaying fire doors, windows, curtain walls and other places that need fire prevention and shock prevention. Multi-layer composite glass can also play anti-theft, bullet-proof and anti-riot properties. This kind of glass is laminated with film or wire between two or three layers of tempered glass, which is called multilayer composite laminated glass. Because tempered glass is selected, its impact resistance is greatly improved. Once broken, the glass fragments will not fall off due to the adhesion of the intermediate film, just like the tempered glass on the car, it is broken or connected, which still acts as a barrier. Installing special multi-layer composite hollow glass can increase the safety factor of doors and windows.
Misunderstanding 4. Good sound insulation effect of vacuum glass: theoretically, the vacuum state is very suitable for sound insulation and heat insulation, just like a vacuum glass, it can be well insulated and heat insulation. However, due to its vacuum, it is difficult for sound to spread on the basis of no medium, therefore, the sound insulation effect is also very good. However, in the real market, because there are many small metal support points inside the vacuum glass, these small metal support points form a "sound Bridge". The larger the glass, the more support points are needed, the vacuum state of vacuum glass is almost lost, which also leads to a great decrease in its sound insulation performance, which is equivalent to the sound insulation effect of two pieces of ordinary glass.
The picture is taken from a program of CCTV. Judging from the sound insulation effect, from the best to the second, it is rubber-laminated hollow glass respectively.
