玻璃幕墙主要用于高层建筑的外部装修。 玻璃幕墙所用的玻璃不是普通玻璃,因为普通玻璃透光性太强,会造成室内采光不够柔和;其近红外线透过率很高,也会带来严重的温室效应。 与普通玻璃相比,幕墙玻璃具有如下一些特点:一是具有控光功能。即通过适当的膜层组合,可将可见光的透过率调节到5％～35％的范围内,对太阳光的近红外和红外辐射具有明显的反射效果。试验结果证明,普通玻璃与幕墙玻璃的遮光能力大不相同,前者的阳光透过率为87％。二是具有防窥作用。由于幕墙玻璃比
Glass curtain wall is mainly used for exterior decoration of high-rise buildings. The glass used in the glass curtain wall is not ordinary glass, because ordinary glass is too light-transmitting and will cause the indoor lighting to be not soft enough; its near-infrared light transmittance is high, and it will also bring serious greenhouse effect. Compared with ordinary glass, curtain wall glass has the following characteristics: First, it has a light control function. That is, through the appropriate combination of layers, the visible light transmittance can be adjusted within the range of 5% to 35%, which has a significant reflection effect on the near-infrared and infrared radiation of sunlight. The test results show that the general glass and curtain wall glass have different light-shielding capabilities, and the former has a solar transmittance of 87%. The second is anti-peeping effect. Due to the curtain wall glass ratio
