Modern curtain wall system
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.
In a unitized system, there are three joint along every mullion and transom. These include the two glasses to aluminium joints and a third joint at the junction between the half mullions and half rails. Should an air or water leak develop at the third joint there is usually no practical method of accessing the in between panel joint of repair unless the manufacturer has provided a serviceable joint system design 26.
n a unitized system, the manufacturer must rely on qualified installers to ensure that the air seals are properly installed between the split mullions. Nevertheless, the unitized system is the most popular facade system according to one manufacturer and it has performed satisfactorily when installed correctly.
Aluminium composite panel with the widest range of colour in P.V.D.F., P.E. and decorative range.
ACP cladding is a new age need for aesthetic elevations.
