ENCAPSULATED PREFABRICATED PANEL
Example embodiments of the described technology provide a prefabricated building panel. The prefabricated building panel may comprise an insulative core having first and second opposing faces. The prefabricated building panel may also comprise a cementitious layer encapsulating the insulative core. The cementitious layer may increase one or more performance characteristics of the panel.
1 . A prefabricated building panel, the panel comprising:
an insulative core having first and second opposing faces; and
a cementitious layer substantially encapsulating the insulative core.
2 . The panel of claim 1 wherein the cementitious layer increases at least one of fire resistance, structural strength and thermal insulative strength of the panel.
3 . The panel of claim 1 wherein the cementitious layer covers at least five surfaces of the insulative core.
4 . The panel of claim 1 wherein the cementitious layer covers all surfaces of the insulative core.
5 . The panel of claim 1 further comprising at least one wick embedded within the cementitious layer, the at least one wick comprising a material having a higher moisture permeability than the cementitious layer.
6 . The panel of claim 5 wherein the at least one wick is embedded in a portion of the cementitious layer which covers a bottom edge surface of the panel.
7 . The panel of claim 5 further comprising a plurality of wicks.
8 . The panel of claim 7 wherein the first face of the insulative core comprises a plurality of grooves configured to direct moisture, each of the plurality of wicks aligned with an end of one groove of the plurality of grooves.
9 . The panel of claim 1 further comprising a structural frame.
10 . The panel of claim 9 wherein the structural frame surrounds the insulative core.
11 . The panel of claim 9 wherein the cementitious layer encapsulates the structural frame.
12 . The panel of claim 9 wherein the structural frame is closer to the first face of the insulative core than the second face.
13 . The panel of claim 9 wherein the structural frame comprises at least one of structural steel, cementitious material, reinforced cementitious material, structural fiberglass, aluminum and carbon fiber.
14 . The panel of claim 1 further comprising at least one connector for coupling the panel to an adjacent panel or an existing structure.
15 . The panel of claim 14 wherein the cementitious layer at least partially encapsulates the connector.
16 . The panel of claim 1 wherein the insulative core defines an aperture for receiving at least one of a window and a door, the cementitious layer at least partially encapsulating surface edges of the insulative core which define the aperture.
17 . The panel of claim 16 wherein the cementitious layer encapsulates all of the surface edges of the insulative core which define the aperture.
18 . The panel of claim 16 wherein portions of the cementitious layer which encapsulate the surface edges of the insulative core which define the aperture are thicker than remaining portions of the cementitious layer.
19 . The panel of claim 1 wherein portions of the cementitious layer which encapsulate edges of the insulative core which surround the first and second opposing faces are thinner than remaining portions of the cementitious layer.
20 . The panel of claim 19 wherein the portions of the cementitious layer which encapsulate the edges of the insulative core which surround the first and second opposing faces have a thickness between ¼ inch and ½ inch.
21 . A method of fabricating a prefabricated panel, the method comprising:
casting a cementitious material;
placing an insulative core over the cast cementitious material; and
casting the cementitious material over remaining portions of the insulative core, the cementitious material substantially encapsulating the insulative core.
