A stick built curtain wall refers to the method of construction by which the curtain wall is assembled on site, piece by piece. The manufacturer delivers each individual component; glass, mullion, spandrel; and glaziers assemble the curtain wall directly on the structure.
The stick built system requires installation by highly skilled laborers on site, increasing the installation cost and causing some quality control issues. However, the on site installation allows for easier detailing of connections and larger tolerances in the building structure.
