Unitized curtain wall system is derived from stick curtain wall system, first designed in Germany. The first time to use this system designed by Chinese company is Project Beijing Textile Building in China in 1997.
This system shortens the building construction schedule on site, can be fixed with the main civil work at the same time, quicker and faster than stick curtain wall system; The quality control work are mainly in the prefabrication factory when assembling unitised panels, project team just guarantees the unitized panels installation quality on site, brackets setting out are correct, brackets connections are correct, the gaps of panels are as designed drawings, much less control points and easier than stick frames system. This system uses male, female mullions at each side of unitized panels, when fixing, always getting male mullion to insert into female mullions, this also determines the installation direction. This system is very mature after more than 20 years developed in China.
In Europe, a new unitized curtain wall system is already in use. It has no male or female mullions, the mullions of it are the same, it use EPDM strip block to replace the male-female flips as vertical sealing lines, connecting with horizontal transoms to guarantee the system sealing properly. This system save the aluminum material, saving energy. This new system also will spread to China in the future as the old one.
