Ventilated roofing tiles

Abstract

Ventilated roofing tiles along with other multilayered energy saving and/or producing constructions are disclosed. Also disclosed are insulating bonding constructions having enhanced energy saving attributes. The ventilated roofing tiles employ heat transfer means that may include natural and/or forced air convection.

1 . A channel containing ventilated roofing tile for transferring heat along underline pitch roofing surfaces of buildings comprising: 
 a rigid multilayer construction having a top surface and bottom surface;    said top surface of said rigid multilayer construction having light reflective characteristics;    said bottom surface of said rigid multilayer construction having channels and attachment means;    wherein said channels are of suitable geometry for moving air by natural convection within said channels along said underlying pitch roofing surfaces, and wherein said attachment means are suitable for fixedly attaching said bottom surface of said rigid multilayer construction to said underlying pitched roofing surfaces.    
   
   
       2 . A ventilated roofing tile comprising: 
 (a) a tile;    (b) a top surface;    (c) a bottom surface;    (d) said top surface is coated with a material to absorb or reflect sunlight and said bottom surface is formed with a plurality of beads thereby improving said tiles ability to attach to a surface.    
   
   
       3 . The ventilated tile of  claim 2  wherein the bottom surface has numerous channels attached to said bottom surface thereby enhancing natural as well as forced air convection.  
   
   
       4 . The multi-layered ventilated tile comprising: 
 (a) a first tile;    (b) a second tile;    (c) said first tile has a bottom surface and a top surface, said bottom surface has a plurality of beads formed into said bottom surface;    (d) said second tile has a top surface and a bottom surface, said top surface a plurality of channels formed into said second tile said top surface;    (e) said first tile is placed over said second tile whereby said channels form a convection zone facilitating a laminar flow of air between said first and said second tiles.
