Composite building and panel systems
A building panel structure is disclosed, in which composite building panels are used to form a structure. A composite building panel is disclosed which includes a core and a coating applied over the core. In some embodiments the core consists of a frame and one or more than one insulating structural block. The insulating structural blocks can be encapsulated polystyrene (EPS) foam blocks. In some embodiments the coating includes an inner scratch layer and an outer main brown layer. The inner scratch layer can be formed of at least two layers. The outer main brown layer can include a fiberglass mesh embedded into the outer main brown layer. A method of forming a building panel structure is disclosed which includes forming a core using a frame and one or more than block, applying an inner scratch layer to the core, and applying an outer main brown layer over the inner scratch layer.
1. A building panel comprising:
a core having a front surface, a rear surface, and side surfaces; and
a coating covering at least a portion of the front or rear surfaces, wherein the coating comprises:
an inner scratch layer, wherein the inner scratch layer consists of at least two layers, the layers comprising:
a first scratch layer A consisting essentially of cement, aggregate, and acrylic bonder; and
a second scratch layer B comprising cement, aggregate, acrylic bonder, fiberglass strands, and fiberglass mesh; and
an outer main brown layer, the outer main brown layer further comprising cement, aggregate, acrylic bonder, fiberglass strands, and fiberglass mesh.
2. The building panel of claim 1 wherein the inner scratch layer comprises a wire mesh.
3. The building panel of claim 1 wherein the outer main brown layer aggregate comprises perlite.
4. The building panel of claim 1 wherein the outer main brown layer aggregate comprises sand.
5. The building panel of claim 1 wherein the core comprises:
a frame; and
one or more than one insulating structural block coupled to the frame.
6. The building panel of claim 5 , wherein the insulating structural block is composed of expanded polystyrene foam.
7. The building panel of claim 5 , wherein the frame is embedded in the one or more than one insulating structural block.
