The choice of window glass has an important impact on the safety, energy efficiency and aesthetics of the building. In modern architectural design, tempered glass has become the preferred material in many window designs because of its unique safety and performance advantages. However, does every kind of window need to use tempered glass? This is also a question that needs to be discussed. In this paper, the characteristics of tempered glass, the advantages and disadvantages of the application of Windows, and the needs of different scenes will be discussed in detail whether the Windows need tempered glass.Help you make better decisions.
The basic characteristics of tempered glass
Tempered glass is a type of glass that has been strengthened by physical or chemical methods. Its main feature is that its strength is several times higher than that of ordinary glass. And when the fragments break, they don't form sharp corners. It has extremely high safety performance. Because tempered glass is heated at high temperatures and then quickly cooled. Forming the structure of internal tensile stress and external compressive stress. This stress structure makes the tempered glass more resistant to external forces. And when impacted or ruptured, the debris breaks down into small, granular pieces. Greatly reduce the harm to the human body.
Strength advantage
The strength of tempered glass is 4-5 times that of ordinary glass. Therefore, it has significant advantages in resistance to shock and pressure. Like some high-rise buildings or external exposed Windows, tempered glass can effectively resist wind pressure, external impact and potential physical collision.For indoor personnel can do a good protection.
Security
Another important feature of tempered glass is safety. When ordinary glass breaks, it will produce sharp fragments, which can easily cause injury to people. Tempered glass will form small particles at obtuse angles when broken, reducing the threat to the human body. This makes tempered glass an ideal choice for Windows in places with high safety requirements.
Thermal stability
The thermal stability of tempered glass is stronger than that of ordinary glass. Can withstand large temperature changes without breaking. For example, in the cold winter and hot summer, the window glass needs to face the temperature difference between the external environment and the indoor environment. Tempered glass can better cope with this situation. Reduces the risk of glass breakage due to thermal expansion or contraction.
The advantage of using tempered glass for Windows
In the design of architectural Windows, tempered glass has many significant advantages. These advantages make it a popular choice for architects and property owners. Specifically, tempered glass has obvious advantages in the following aspects.
Security guarantee
Since the Windows are the exposed part of the exterior wall of the building, they may face various risks from the outside, such as impact, wind pressure, and atmosphere. Especially in tall buildings. Broken window glass not only poses a threat to the safety of indoor and outdoor personnel, but also may cause injury to pedestrians and vehicles outside the building. The impact resistance and granular properties of tempered glass when broken. It can greatly reduce these risks and ensure the safety of the living environment.
Wind pressure resistance
For some tall buildings and buildings in coastal areas. The window glass needs to withstand relatively high wind pressure. Especially when the typhoon is coming, the strength of the window glass needs to be greatly improved. Ordinary glass is easily broken by impact in bad weather. Tempered glass can withstand greater wind pressure due to its high strength and toughness. This can avoid the danger of breaking the glass.
Prevent accidental collision
In residential or commercial buildings, window glass can sometimes break as a result of accidental collisions, such as when a child is playing or when furniture is being moved. The high strength of tempered glass allows it to effectively resist these unexpected shocks, reducing the risk of breakage. Therefore, the tempered glass extends the service life of the window.
Thermal stability and energy saving effect
Tempered glass has better human stability. In particular, it is not easy to break under extreme temperature conditions. Its better insulation also helps the building save energy. In double or multi-layer glass structures, tempered glass is often used for the outer layer. Provides additional protection and energy savings. The cooling and heating gas consumption of the building is reduced.
Seismic capability
For buildings in earthquake-prone areas, the seismic resistance of Windows is crucial. Tempered glass due to its structural stability. It can maintain high integrity in natural disasters such as earthquakes. The risk of glass cracking and falling is reduced, thus providing better security for residents.
Windows that do not use tempered glass
Although tempered glass has advantages in many ways, it is not suitable for all cases. The following mainly introduces the scene that is not suitable for the use of tempered glass.
Low rise building or interior Windows
In low-rise buildings, Windows face less wind pressure and have less interaction with the outside world. Therefore, ordinary glass can also play a protective role in the general environment. Although the strength is not as strong as tempered glass, it is enough for daily life. Similarly, the Windows used inside the building do not need to withstand the impact of the external environment. Therefore, ordinary glass also meets the demand inside the building.
Cost consideration
The manufacturing cost of tempered glass is higher than that of ordinary glass. After all, the strength and safety of tempered glass are very high. Especially for large-area Windows, the use of tempered glass will significantly increase the cost of the project. If the budget of the building is limited. And Windows don't need to face larger shocks or wind pressure, and regular glass may be a more economical option.
Aesthetic demand
In some cases, architects may want to choose more decorative or special treatment glass (such as patterned glass, stained glass, etc.) to enhance the aesthetic effect of the building. And these glasses don't necessarily need to be tempered. For some aesthetically oriented, and security requirements are not high occasions. In fact, non-tempered glass can better meet the design needs. Therefore, our choice of glass also depends on the needs of the occasion.
The disadvantage of tempered glass
Tempered glass does have many advantages. But inevitably there must be corresponding shortcomings.The following mainly introduces the shortcomings of tempered glass to help you better understand its characteristics.
The complexity of production and installation
Once the tempered glass has been strengthened, it can no longer be cut or processed. Therefore, in the manufacturing process, we must ensure the size and details of the glass. Otherwise, the glass will be scrapped directly because of processing errors, but increase the cost.
Self-detonation risk
People who know a little about tempered glass know that there is a risk of self-explosion. It's possible that the glass was not subjected to an external force and still suddenly cracked. This phenomenon may be caused by the inclusion of nickel sulfide inside the glass, even if the probability is low. But as long as it appears, it will have an impact on its security. In order to avoid this situation, many buildings will choose to use tempered glass with low nickel sulfide content.
Higher cost
The price of tempered glass is generally 20% to 50% higher than that of ordinary glass. That's a big budget for a big building project. Therefore, for projects with tight budgets, the use of tempered glass needs to be carefully considered.
Tempered glass requirements in different scenarios
High-rise building
The Windows of high-rise buildings are exposed to high wind pressure and extreme weather, and tempered glass is an essential choice. In this environment, tempered glass can bring a full sense of security, but also improve shock resistance and impact resistance.
Commercial building
For shopping malls, office buildings and other commercial buildings, especially in areas with high traffic. Tempered glass can better ensure the safety of people. Helps reduce the risk of accidents caused by broken glass. In addition, the transparency and aesthetics of tempered glass can also enhance the overall visual effect of the building.
Family house
In family homes, tempered glass is mainly used in external Windows, balcony guardrail and other areas. Especially in the case of children in the family, tempered glass can reduce the damage caused by collisions. Improved home security.
Special environment
In some special environments, such as high earthquake incidence areas, coastal areas, industrial parks, etc. If you choose tempered glass material, you can better face the harsh weather environment.
Conclusion
In summary, whether the window needs to use tempered glass depends on a variety of factors. For high-rise buildings, commercial buildings and places with high safety requirements, tempered glass is an ideal choice. Strength, safety, wind pressure resistance can be guaranteed. For low-rise residential or indoor Windows, the use of ordinary glass can actually meet the needs. There are also advantages in terms of cost and aesthetics. According to your own needs and budget costs, I believe you can choose a more suitable type of glass.
