What is stick system curtain wall?
The Stick System is a curtain walling system consisting normally of extruded aluminium transoms (anchored to a slab or sub structure) and mullions known as “sticks” which are cut to length in the factory prior to assembly on site which may compromise of mechanically held fixed or open glazing (single pane or double glazed units), metal insulated panels (aluminium, stainless steel, aluminium, titanium etc.) or stone insulated panels (marble, granite etc.)
The characteristics of this system makes designing flexible whilst permitting complex and irregular 3d surfaces to be built.
Stick curtain wall are processed, manufactured at factory and assembled, installed and completed at site. This kind of curtain wall can be used for all outside surface system types of buildings and especially suitable for sophisticated and multiple joint structure architecture.
