Abstract:
1. A high impact and load bearing building panel comprises: a first magnesium oxide board; a phenolic resin sheet having a first edge and a second opposing edge, wherein the phenolic resin sheet provides fire resistance and impact absorbance; an expanded polystyrene layer having a first edge and a second opposing edge, and a plurality of spline-receiving grooves traversing into the expanded polystyrene, wherein each spline-receiving groove is positioned at each corner of the expanded polystyrene layer; a second magnesium oxide board; the phenolic resin sheet being adjacently laminated with the expanded polystyrene layer such that the first edge of the phenolic resin sheet is coincident with the first edge of the expanded polystyrene layer, and wherein the second edge of the phenolic resin sheet is extended beyond the second edge of the expanded polystyrene layer to form a seal section; the first magnesium oxide board being adjacently laminated to the phenolic resin sheet opposite from the expanded polystyrene layer; the second magnesium oxide board being adjacently laminated to the expanded polystyrene layer opposite from the phenolic resin sheet; the first magnesium oxide board and the phenolic resin sheet form a non-brittle outer layer; and wherein the first magnesium board, the second magnesium board and the expanded polystyrene layer are coextensive to each other.
