1.节能(néng)性：

      U型玻璃的传热系数较低（双层U玻 K=2.39W／m2k），有(yǒu)良好的隔热保温性能(néng)。现有(yǒu)幕墙上常用(yòng)的普通中空玻璃的传热系数在3.38 W／m2k和3.115 W／m2k之间，比双层U型玻璃的保温性能(néng)差。

2．U型玻璃安装施工简便快捷：

      因U型玻璃直接可(kě)以作為(wèi)幕墙的主受力构件，相对于普通玻璃幕墙，省去了大量龙骨等附件，制作安装简便快捷，大大缩短了工期。

3. U型玻璃是绿色环保产品：

      因U型玻璃的透光率较高，应用(yòng)于厂房等公共建筑时，既节约建筑物(wù)室内照明费用(yòng)，又(yòu)兼有(yǒu)人性化的工作环境。而且U型玻璃可(kě)采用(yòng)回收碎、废玻璃再生产，保护了环境。

2.经济性：　　

 U型玻璃是采用(yòng)连续压延法成型的玻璃型材，使建筑玻璃由板材发展到型材，所以其综合成本相对较低，采用(yòng)U型玻璃组合幕墙可(kě)节省大量钢或铝型材

1. Energy saving:
The heat transfer coefficient of u-shaped glass is low (double layer U glass K= 2.39w/m2k), and it has good thermal insulation performance. The heat transfer coefficient of common insulating glass commonly used on existing curtain walls is between 3.38w/m2k and 3.115w/m2k, which is worse than that of double-layer u-shaped glass.
2. U-shaped glass installation and construction is simple and fast:
Because U type glass can be used as the main force component of the curtain wall directly, compared with the ordinary glass curtain wall, it saves a lot of accessories such as keel, which is easy to make and install and greatly shortens the construction period.
3. U-shaped glass is a green environmental protection product:
Due to the high transmittance of u-shaped glass, when it is used in public buildings such as factory buildings, it can not only save the cost of indoor lighting, but also provide a humanized working environment. And U - shaped glass can be recycled broken, waste glass reproduction, to protect the environment.
2. Economy:
U-shaped glass is the glass profile formed by continuous rolling method, which makes the building glass develop from plate to profile, so its comprehensive cost is relatively low. The use of u-shaped glass composite curtain wall can save a lot of steel or aluminum profiles
