Stick & Unitized Curtain wall

Project details

In a general sense, the term “curtain wall” refers to an exterior wall that does not support loads other than its own weight. Curtain walls are therefore non-structural and serve solely to protect the building from the elements. Seismic and wind forces on a curtain wall are transferred to the supporting structure at anchorage points, where the curtain wall frame is attached to the building, generally at floors or columns.

Glazed curtain walls usually consist of a metal frame, often aluminum, with in-fills of vision and spandrel glass. Other materials may be interpolated between glazing units, including brick veneer, precast concrete, metal panels, and thin stone.

Glass curtain walls consist of two basic components: the glass and the frame. How these two elements are manipulated, including the proportion, properties, and anchorage of each, constitutes the essential distinction among individual curtain wall systems.

Composed of steel, aluminum, multi-laminate glass, or other resilient material, the frame is the support grid that holds the glass in place.

  • Stick systems are curtain walls at their most basic, with individual mullions, or framing elements, assembled in the field.
  • Unitized systems apply the same design principles as stick systems, but sections of the curtain wall are as¬sembled in the shop and installed as a unit.
  • Unit mullion systems combine the pre-assembled pan¬els of unitized systems with the multi-story vertical mul¬lions of stick systems. Upright mullions are installed first, with horizontal mullions and glazing installed as a unit.
  • Column cover and spandrel systems articulate the building frame by aligning mullions to structural columns. Pre-assembled or field-assembled infill units of glass or opaque panels are fitted between the column covers.
  • oint-loaded structural glazing systems eliminate visible metal framework by incorporating tension cables, truss¬es, glass mullions, or other custom support structures behind the glass panels. Glazing is anchored by brackets or by proprietary hardware embedded in the glass
