U型玻璃是一種新型節能環(huán)保的墻體材料，上世紀90年代開(kāi)始在我國逐步應用于各地建筑物的內、外圍護結構，在2010年上海世博會(huì )展區的智利國家館也得到了很好的展示。 

近年來(lái)U型玻璃得到國內外建筑設計師的關(guān)注和青睞，國家建筑標準院出版了安裝應用的圖集。不少建筑專(zhuān)業(yè)的專(zhuān)家也在報刊雜志上對U型玻璃進(jìn)行介紹和論述，特別是中國工程院院士、上海同濟大學(xué)原規劃院院長(cháng)、博士生導師戴復東就格外推崇。

U-shaped glass is a new type of energy-saving and environment-friendly wall material. Since the 1990s, u-shaped glass has been gradually applied in the interior and exterior protection structures of buildings in China. It was also well displayed in the national pavilion of Chile in the exhibition area of Shanghai world expo in 2010.
In recent years, u-shaped glass has gained the attention and favor of architects at home and abroad. Many experts of architecture also introduced and discussed u-shaped glass in newspapers and magazines, especially dai fudong, academician of Chinese academy of engineering, former dean of Shanghai tongji university and doctoral supervisor.
The heat transfer process of u-shaped glass wall
Heat transfer between the outer surface of u-shaped glass and the surrounding air and the external environment, including convection heat transfer between the outer surface and the surrounding air, solar radiation heat absorbed and reflected by the outer surface, and long-wave radiation heat transfer between the outer surface and space.
Heat transfer between the outer surface of u-shaped glass and the surrounding air and the external environment, including heat transfer between the outer surface and the surrounding air and the indoor environment, convection heat transfer between the inner surface and the indoor air, and long-wave radiation heat transfer between the inner surface and the indoor environment.
Heat transfer and heat conduction of u-shaped glass walls and surrounding metal frames. Thermal calculation of u-shaped glass wall (according to 41 * 6 specifications)
