## Abstract

Structural panels are provided which utilize commercially available components and a cost effective method of fabrication. The structural panels include commercially available trusses, fillers positioned between and aligned with the trusses and sandwiched to form a solid panel core, and commercially available wire mesh substantially covering opposing side surfaces of the panel core and attached to the trusses with wire to hold the panel core together. The trusses include generally parallel rods and wire bent around the rods in a zigzag configuration. The fillers may include a foamed filler such as solid foamed plastic or solid foamed glass. Alternatively, the filler may include a stabilized organic material. A commercially available lathing member may also be imbedded into the structural panel. The structural panels are fabricated by aligning the fillers and trusses in an alternating sequence. The alternating masonry reinforcement trusses and fillers are then pressed to form a panel core. The wire mesh is overlied on opposing side surfaces of the panel core and attached to the trusses by attaching metal ties to connection points of the wire mesh and trusses to hold the panel core together. A durable coating can then be applied to the panel core and attached wire mesh.

## Claims

### Claim 1

A pre-fabricated structural panel, comprising:
a plurality of commercially available trusses having substantially parallel rods of identical width interconnected by wire bent around the rods in a zigzag configuration;
a plurality of solid foamed glass fillers positioned between and aligned with the trusses and sandwiched therebetween under pressure to form a solid panel core;
commercially available wire mesh substantially covering opposing side surfaces of the panel core and attached to the rods of the trusses with commercially available metal ties to hold the panel core together; and
a commercially available lathing member imbedded within the structural panel wherein said lathing member acts as a secure anchor for attachment of at least one finished board.

### Claim 2 (depends on 1)

The structural panel of claim 1, wherein the trusses comprise masonry reinforcement trusses having wire bent around the rods at approximately 30° angles.

### Claim 3 (depends on 1)

The structural panel of claim 1, including a durable coating overlying the panel core and attached wire mesh.

### Claim 4

A pre-fabricated structural panel, comprising:
a plurality of commercially available trusses having substantially parallel rods of identical width interconnected by wire bent around the rods in a zigzag configuration;
a plurality of fillers comprised of stabilized biomass positioned between and aligned with the trusses and sandwiched therebetween to form a panel core;
commercially available wire mesh substantially covering opposing side surfaces of the panel core and attached to the rods of the trusses with commercially available metal ties to hold the panel core together; and
a commercially available lathing member imbedded within the structural panel wherein said lathing member acts as a secure anchor for attachment of at least one finished board.

### Claim 5 (depends on 4)

The structural panel of claim 4, wherein the trusses comprise masonry reinforcement trusses having wire bent around the rods at approximately 30° angles.

### Claim 6 (depends on 4)

The structural panel of claim 4, including a durable coating overlying the panel core and attached wire mesh.
