Claim Text:
1. A method for insulating a building, comprising: (a) affixing one or more rigid brackets to a planar surface of a structural material of the building by one or more mechanical fasteners, wherein each of the one or more rigid brackets includes a platform bearing a planar surface facing substantially away from the planar surface of the structural material, wherein the surface area of the planar surface of each of the one or more rigid brackets is substantially smaller than the surface area of the planar surface of the structural material to which it is affixed, wherein each of the one or more rigid brackets has first and second sides appending from the platform away from the planar surface thereof and a bottom panel extending from the first side to the second side, wherein each of the first and second sides defines a proximal portion and a distal portion therealong, wherein the distal portion of the first side is inwardly directed toward the distal portion of the second side, wherein the bottom panel extends from the distal portion of the first side to the distal portion of the second side, wherein the one or more rigid brackets are formed from a single piece of metal, wherein the one or more rigid brackets are affixed to the planar surface of the structural material at the distal portion of the first side and the distal portion of the second side; and (b) spraying a rigid, closed-cell, spray polyurethane foam contiguous to substantially cover the planar surface of the structural material and fill and surround and/or embed at least a major portion of the one or more rigid brackets.
