Attic baffle radiant barrier ventilation system

Abstract

An attic baffle radiant barrier for use in unvented attics and vented attics. The attic baffle has a baffle substrate with an elongated H-shape, with a cross-span extending between two legs on the left and right, each leg comprising an upper portion and a lower portion. A tab or extension extends from the respective ends of one or both portions of one or both legs of the “H”. A radiant barrier layer is affixed or adhered to one side of the baffle substrate. The tabs or extensions may be used for stapling (i.e., using staples) or otherwise fastening the attic baffle radiant barrier to the bottoms, tops, or sides of rafter studs or trusses or similar frame members when installed.

What is claimed is: 
     
         1 . An attic baffle radiant barrier, comprising:
 a baffle substrate, comprising a cross-span with an upper surface, a lower surface, a first edge, and a second edge, said cross-span extending between a first leg and a second leg, said first edge attached to the first leg and said second edge attached to the second leg;   a first tab extending from an end of the first leg;   a second tab extending from an end of the second leg; and   a radiant barrier layer affixed to the upper surface or lower surface of the cross-span.   
     
     
         2 . The attic baffle radiant barrier of  claim 1 , wherein the radiant barrier layer contiguously extends to and is affixed to an inner surface of the first leg and an inner surface of the second leg. 
     
     
         3 . The attic baffle radiant barrier of  claim 1 , wherein the first edge is integrated with and contiguous with the first leg, and the second edge in integrated with and contiguous with the second leg. 
     
     
         4 . The attic baffle radiant barrier of  claim 1 , wherein the first tab and second tab extend outwardly from the end of the respective leg. 
     
     
         5 . The attic baffle radiant barrier of  claim 4 , wherein the first tab and second tab extend outwardly at an acute angle with respect to the respective leg. 
     
     
         6 . The attic baffle radiant barrier of  claim 1 , wherein the first edge is foldingly or flexibly attached to the first leg, and said second edge is foldingly or flexibly attached to the second leg. 
     
     
         7 . The attic baffle radiant barrier of  claim 1 , wherein the first tab is foldingly or flexibly attached to the first leg, and said second tab is foldingly or flexibly attached to the second leg. 
     
     
         8 . The attic baffle radiant barrier of  claim 1 , wherein the first tab is attached to a lower end of the first leg and the second tab is attached to a lower end of the second leg, and the radiant barrier layer extends across the entirety of the lower surface of the cross-span and down the adjacent faces of the respective legs to the lower end of each respective leg. 
     
     
         9 . The attic baffle radiant barrier of  claim 1 , wherein the radiant barrier layer comprises an aluminum sheet or foil. 
     
     
         10 . The attic baffle radiant barrier of  claim 1 , wherein the radiant barrier layer comprises a copper sheet or foil. 
     
     
         11 . The attic baffle radiant barrier of  claim 1 , wherein the radiant barrier layer comprises a sprayed-on metallic substance. 
     
     
         12 . The attic baffle radiant barrier of  claim 1 , wherein the radiant barrier layer comprises a brushed-on metallic substance. 
     
     
         13 . The attic baffle radiant barrier of  claim 1 , wherein the baffle substrate comprises paperboard. 
     
     
         14 . The attic baffle radiant barrier of  claim 1 , wherein the baffle substrate comprises plastic.
