Unitised Curtain Wall
The Unitized curtain wall is the most airtight weather resistant cladding and exterior wall system available. A glass and aluminium curtain wall fabricated in factory and installed as a panel system is reffered to as a unitized curtain wall system. Unitized curtain wall will comprise glass vision panel and spandrel panel mounted in a prefabricated aluminium frame. Most of the system components are assembled in s plant under controlled working conditions. This promotes Quality assembly and allows for fabrication lead-time and rapid closure of the building. the unitized system is assembled on the building as panels. The structural section around the panel is fabricated as half sections instead a whole section which mate at assembly time to form the curtain wall system. The panels are installed in shingle fashion, starting either from the bottom or top of the building and going around each floor until the while building is dressed up. While the unitized system offers many advantages with respect to quality assembly and speed up the site construction time, there is one design concern with respect to installed performance and durability.
