Claim Text:
1. An insulating and venting panel assembly, comprising: a. an insulating rigid foam sheet having heat and cold insulating capabilities, the insulating rigid foam sheet comprising a composition selected from the group consisting of expanded polystyrene, extended polystyrene, polyisocyanurate rigid foam and other insulating rigid foam material; b. air spacers comprising non-collapsing columns that are extruded, molded or cut on an upper face of the insulating rigid foam sheet; c. air spaces formed in between the non-collapsing columns, said air spaces having a depth of approximately ¾ to 1½ inches; d. an upper rigid board comprising a composition selected from the group consisting of oriented strand board, plywood or other composition material; e. a radiant barrier low emissivity surface attached to a lower face of the upper rigid board, said radiant barrier lower emissivity surface configured to reradiate a low amount of radiant heat when facing said air spaces; f. each air spacer comprising an air spacer outer end having a width approximately ½ to 1 inch wide, each air spacer outer end facing outward from the upper face of the insulating rigid foam sheet and is attached to the radiant barrier low emissivity surface; g. a lower rigid board comprising a composition selected from the group selected from oriented strand board, plywood or other composition material, wherein the lower rigid board is attached to a lower face of the insulating rigid foam sheet opposite a side of the rigid foam sheet that the upper rigid board is attached thereto; h. wherein the radiant barrier low emissivity surface is attached to the insulating rigid foam sheet; i. wherein, approximately 10 to 15 percent, of the air spacer outer ends are attached to and touching the radiant barrier low emissivity surface, configured to minimize radiant heat radiation from the radiant barrier low emissivity surface; j. wherein heat is transferred by conduction from the radiant barrier low emissivity surface to the air spacer outer ends and/or at least one surface of the air spaces; k. wherein said air spaces can vent air and moisture vapor, including convectively venting heated air generated from the air spacer outer ends and/or the at least one surface of the air spaces heated by conduction, to flow through said air spaces; l. wherein, the insulating and venting panel assembly is placed on, and is configured to be attached to a top surface of roof rafters, in a roofing application, so that said air spacers attached to the radiant barrier lower emissivity surface extends away from the top surface of the roof rafters for adjoining other insulating and venting panel assemblies in the roof application, wherein the air spaces adjoin air spaces of the other insulating and venting panel assemblies, allowing for venting out air and moisture vapor from the roof; and m. wherein compression stability of the non-collapsing columns is configured to allow applied roofing materials including asphalt or fiberglass shingles, tiles, and metal roofing to be attached to the upper rigid board.
