Radiant Barrier Ventilation System

Abstract

This invention relates to a system of ventilating a residential or light commercial structure with lightweight, easy to install radiant barriers that reflect external sunlight heat away from the structure, reflect heat produced within the structure to maintain internal warmth, and contain internal air ventilation space to prevent condensation.

         5 . The insulation ventilation system for the roof structure of  claim 1 , wherein the edges of the plurality of radiant barriers are attached to form overlapping substantially parallel edges. 
     
     
         6 . The insulation ventilation system for the roof structure of  claim 1 , wherein each radiant barrier is expandable from 5 inches to 30 inches. 
     
     
         7 . The insulation ventilation system for the roof structure of  claim 1 , wherein the heat reflective substantially flat material comprises substantially fireproof Mylar sheet. 
     
     
         8 . The insulation ventilation system for the roof structure of  claim 1 , wherein the heat reflective substantially flat material comprises substantially fireproof aluminum sheet. 
     
     
         9 . The insulation ventilation system for the roof structure of  claim 1 , wherein the radiant barriers comprise a foam board core. 
     
     
         10 . An improved insulation ventilation system for a wall structure comprising:
 a load bearing wall frame with a plurality of vertical members;   a plurality of substantially flat radiant barriers, wherein each radiant barrier comprises a substantially rectangular shape, a first surface, a second surface, a top edge, a bottom edge, a first side edge, a second side edge, and a plurality of substantially parallel fold lines, further wherein the fold lines produce an accordion cross-section shape for the barrier with a plurality of adjacent oppositely pointing apexes on the first surface and the second surface;   a plurality of substantially parallel air holes between each of the fold lines;   a heat reflective substantially flat material on the first surface and the second surface;   wherein the plurality of radiant barriers is attached on one of the edges to the plurality of vertical members with the first surface facing outwards and the second surface facing inwards, further wherein the plurality of radiant barriers are attached to each other along the edges to form at least one layer between the plurality of vertical members;   wherein the first surfaces of the attached plurality of radiant barriers substantially reflects radiant heat from external sunlight, and the second surfaces of the attached plurality of radiant barriers substantially reflects radiant heat from internal structure heat; and   the accordion cross-section shape for the barriers produces air space on the first and second surfaces of the attached plurality of radiant barriers.   
     
     
         11 . The insulation ventilation system for the wall structure of  claim 10 , wherein the wall frame is made out of at least one of a group of materials consisting of solid wood, timber materials, engineered wood products, wood composite materials, steel and aluminum. 
     
     
         12 . The insulation ventilation system for the wall structure of  claim 10 , wherein angle of each oppositely pointing apexes comprises an angle of 0 degrees to 180 degrees. 
     
     
         13 . The insulation ventilation system for the wall structure of  claim 10 , wherein the plurality of radiant barriers is attached to form two overlapping substantially parallel layers between the plurality of vertical members. 
     
     
         14 . The insulation ventilation system for the wall structure of  claim 10 , wherein the edges of the plurality of radiant barriers are attached to form overlapping substantially parallel edges.
