1.節能性：

      U型玻璃的傳熱系數較低（雙層U玻 K=2.39W／m2k），有良好的隔熱保溫性能?，F有幕墻上常用的普通中空玻璃的傳熱系數在3.38 W／m2k和3.115 W／m2k之間，比雙層U型玻璃的保溫性能差。

2．U型玻璃安裝施工簡(jiǎn)便快捷：

      因U型玻璃直接可以作為幕墻的主受力構件，相對于普通玻璃幕墻，省去了大量龍骨等附件，制作安裝簡(jiǎn)便快捷，大大縮短了工期。

3. U型玻璃是綠色環(huán)保產(chǎn)品：

      因U型玻璃的透光率較高，應用于廠(chǎng)房等公共建筑時(shí)，既節約建筑物室內照明費用，又兼有人性化的工作環(huán)境。而且U型玻璃可采用回收碎、廢玻璃再生產(chǎn)，保護了環(huán)境。

2.經(jīng)濟性：　　

 U型玻璃是采用連續壓延法成型的玻璃型材，使建筑玻璃由板材發(fā)展到型材，所以其綜合成本相對較低，采用U型玻璃組合幕墻可節省大量鋼或鋁型材

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
