从金属和玻璃幕墙的主要性能讲,其要求是多方面的,本文着重讨论要有足够的防水功能与相当的抗透风能力。我们曾经调查了一些幕墙工程。这些建筑的主人抱怨他们的幕墙透风严重,漏水过多。事实上,其中的一些墙在正式安装以前曾进行过实验,设计是按照精确测定的性能标准进行。这些墙本身也是按图施工,失败的原因在于墙体与框架的接缝和密封的失 From the main performance of metal and glass curtain wall, its requirements are many, this article focuses on the need for adequate waterproof function and considerable anti-ventilation capabilities. We have investigated some curtain wall projects. The owners of these buildings complained that their curtain walls were seriously ventilated and leaked too much water. In fact, some of these walls were tested before they were officially installed, and the design was based on accurately measured performance standards. The walls themselves are also constructed according to the drawings. The reason for the failure is the loss of joints and seals between the wall and the frame.
