Abstract: A curtain wall or paneling system for concealing and beautifying an existing structural wall features a pair of elongated, upper cap and lower sill-forming channel members which are attached in predetermined, vertically spaced relation on the existing wall and which support and hold a plurality of transversely spaced apart, vertically elongated metallic studs or pilasters and decorative wall panels. The length of the studs and wall panels are correlated to the spacing between and depth of the upper cap and lower sill channel members, so that they may be easily lifted into and out of engagement with the cap and sill channel members.
