Understanding Window Glass Types

---

Choosing a window class depends on the application and the performance required.  The type of glass may be dictated by building codes, along with the number of glazing options available to improve energy efficiency. You’ll also want to select a glass type based on the desired application – some glass types are more resistant to force and deflection.   

选择窗户类别取决于应用场景和所需的性能。玻璃的类型可能由建筑规范决定，同时还有多种玻璃选项可用于提高能源效率。此外，您还需要根据预期应用选择玻璃类型——某些玻璃类型对外力和变形的抵抗力更强。  

Annealed Glass 退火玻璃

Annealed glass is raw glass that’s sometimes also called standard glass. It has a tendency to break into large, sharp pieces which means it’s limited by many codes. This is used when the cost is the highest concern, not strength, safety, or efficiency. 

退火玻璃是未经处理的原玻璃，有时也被称为标准玻璃。它容易破碎成大而锋利的碎片，因此受到许多规范的限制。退火玻璃通常用于成本是首要考虑因素，而非强度、安全性或效率的场合。

Tempered Glass 钢化玻璃

Tempered glass undergoes controlled heating and rapid cooling, which makes it roughly four times as strong as annealed. It is significantly more shatter-resistant and breaks into small pieces when it does shatter, meaning it is far less likely to cause injury. Tempered glass is a popular choice for buildings, although tempered glass only improves safety – not thermal comfort or impact resistance. 

 钢化玻璃经过受控加热和快速冷却处理，其强度大约是退火玻璃的四倍。它具有显著的抗碎裂性能，当破碎时会分裂成小块，因此更不容易造成伤害。钢化玻璃在建筑物中非常受欢迎，尽管钢化玻璃仅能提高安全性，但对热舒适性或抗冲击性没有提升。 

 Dual-glazed Glass 双层玻璃

 Dual-glazed windows are made by combing two layers of glass. In some cases, the space between the layers is filled with material. Commonly, it’s left empty and then filled with an inert gas to help increase the glass’ resistance to energy transfer. Temperature transmission is reduced by introducing airspace and creating a thermal break in the glass. Although triple glazing is also an option, dual-glazed is often the most cost-effective choice. 

 双层玻璃窗由两层玻璃组合而成。在某些情况下，两层玻璃之间的空间会填充材料。通常，这个空间是空的，然后填充惰性气体，以帮助提高玻璃对能量传递的抵抗力。通过引入空气间隙并在玻璃中创建热断层，可以减少温度传递。尽管三层玻璃也是一种选择，但双层玻璃通常是最具成本效益的选择。 

Laminated Glass 夹层玻璃

Laminated glass is created by combining two layers of annealed glass together with vinyl. The vinyl layer helps hold the glass in place if it’s broken, causing less damage. This makes it a popular choice in commercial applications. 

 夹层玻璃是通过将两层退火玻璃与乙烯基层结合在一起制成的。如果玻璃破碎，乙烯基层可以帮助将玻璃固定在原位，从而减少损坏。这使得夹层玻璃在商业应用中非常受欢迎。 

Low-e(low-emissivity) Glass  低辐射（Low-E）玻璃 

Low-e(low-emissivity) glass uses a thin coating to limit the amount of ultraviolet and infrared light that passes through the glass. This helps increase the performance of the windows and makes them more energy-efficient.

低辐射（Low-E）玻璃使用一层薄涂层来限制紫外线和红外线通过玻璃。这有助于提高窗户的性能，使其更加节能。

Beyond window classes and glass types, you’ll also want to consider your  glazing, coating, and filming options. These additional steps can help increase your glass’ resistance to damage and ability to insulate. 

除了窗户类别和玻璃类型外，您还需要考虑您的玻璃镀膜、涂层和薄膜选项。这些额外的步骤可以帮助提高玻璃的抗损坏能力和隔热性能。
