Precast Panel : Cladding or curtain walls

Precast concrete panels do not transfer vertical loads but simply enclose the space. They are only designed to resist wind, seismic forces generated by their own weight, and forces required to transfer the weight of the panel to the support.

Common cladding units include

wall panels
window wall units
spandrels
mullions
column covers

These units can usually be removed individually if necessary.
