## Abstract

A prefabricated wall panel includes molds for casting reinforced concrete (RC) elements. The prefabricated wall panel includes foam boards, foam glass panels fixed to the foam boards, fabric mesh fixed to the foam glass panels, wire mesh fixed to the fabric mesh, and an exterior wall finish fixed to the wire mesh. Spaces defined by the foam boards and the foam glass panels form the molds for casting RC columns and beams.

## Claims

### Claim 1

A prefabricated wall panel system, comprising:
full-height prefabricated wall panels;
a less-than-full-height upper prefabricated wall panel fixed between the full-height prefabricated wall panels to define a window or a door opening below the less-than-full-height upper prefabricated wall panel and between the full-height prefabricated wall panels;
wherein at least one of the full-height and the less-than-full-height upper prefabricated wall panel comprises:
one or more foam boards;
foam glass panels fixed to the one or more foam boards;
fabric mesh fixed to the foam glass panels;
wire mesh fixed to the fabric mesh; and
exterior wall finish fixed to the wire mesh.

### Claim 2 (depends on 1)

The system of claim 1, wherein spaces defined by the one or more foam boards and the foam glass panels form molds for casting reinforced concrete elements.

### Claim 3 (depends on 1)

The system of claim 1, wherein each full-height prefabricated wall panels is selected from the group consisting of straight and L-shaped corner prefabricated wall panels.

### Claim 4 (depends on 1)

The system of claim 1, further comprising a less-than-full-height lower prefabricated wall panel fixed between the full-height prefabricated wall panels below the less-than-full-height upper prefabricated wall panel to define the window opening.

### Claim 5 (depends on 4)

The system of claim 4, wherein the less-than-full-height upper and lower prefabricated wall panel are selected from the group consisting of rectilinear and polygonal less-than-full-height upper and lower prefabricated wall panels.
