The Testing and Analysis for Physical Performances of Building Curtain Walls Under Condition of High-low Temperature Cycles

This article analyses the changing of some performance parameters of modern building curtain walls of some plaza in Chongqing city, by proceeding the tests of air permeability performance, water-tightness performance, wind resistance performance, performance in plane deformation, and high-low temperature cycles. Present and proceed the testing method of high-low temperature cycles for the first time in this testing field.
