Composite Construction Panels and Applications Thereof

Abstract

In one aspect, composite construction materials are described herein. In some embodiments, a composite construction panel comprises a substrate layer, a cover layer separated from the substrate layer by one or more spacers, and at least one mat disposed between the substrate layer and the cover layer, wherein the mat comprises at least one phase change material disposed in at least one phase change region.

That which is claimed is: 
     
         1 - 20 . (canceled) 
     
     
         21 . A method of making a composite construction panel, the method comprising:
 adhering a first mat to a top surface of a substrate layer, the first mat comprising at least one first phase change material disposed in at least one first phase change region;   adhering one or more first spacers to the top surface of the substrate layer; and   adhering a cover to the one or more first spacers.   
     
     
         22 . The method of  claim 21 , wherein:
 the cover is separated from the substrate layer by the one or more first spacers; and   the one or more first spacers define one or more first vent spaces, cross vent channels, or both.   
     
     
         23 . The method of  claim 22  further comprising:
 disposing a second mat between the first mat and the cover, the second mat comprising at least one second phase change material disposed in at least one second phase change region; and 
 disposing one or more second spacers between the second mat and the cover. 
 
     
     
         24 . The method of  claim 23 , wherein:
 the first mat and the second mat are vertically separated from one another in a stacked configuration by the one or more second spacers; and   the one or more second spacers define one or more second vent spaces, cross vent channels, or both.   
     
     
         25 . The method of  claim 23 , wherein the first and second phase change materials are differing phase change materials. 
     
     
         26 . The method of  claim 25 , wherein the first phase change material has a transition temperature below 30° C. and the second phase change material has a transition temperature above 30° C. 
     
     
         27 . The method of  claim 21 , wherein one or both of the substrate layer and the cover is formed from a foam. 
     
     
         28 . The method of  claim 27 , wherein the foam comprises polyurethane or polyisocyanurate. 
     
     
         29 . The method of  claim 27 , wherein a fire retardant or extinguisher is disposed in the foam. 
     
     
         30 . The method of  claim 27 , wherein a phase change material is disposed in the foam. 
     
     
         31 . The method of  claim 21 , wherein one or both of the substrate layer and the cover is formed from wood, plywood, particle board, or oriented strand board. 
     
     
         32 . The method of  claim 21 , wherein one or both of the substrate layer and the cover is formed from gypsum board. 
     
     
         33 . The method of  claim 21 , wherein one or both of the substrate layer and the cover is formed from metal. 
     
     
         34 . The method of  claim 24 , wherein at least one spacer is hollow and one or more salt hydrates is disposed in the interior of the hollow spacer. 
     
     
         35 . The method of  claim 24 , wherein the one or more first or second vent spaces, cross vent channels, or both are sealed. 
     
     
         36 . The method of  claim 24 , wherein the panel is coupled to one or more fans operable to ventilate or provide air flow in the one or more first and/or second vent spaces, cross vent channels, or both. 
     
     
         37 . The method of  claim 23 , wherein at least one of the first mat or the second mat comprises a plurality of phase change regions arranged in a plurality of rows, the rows comprising differing phase change materials.
