         5 . The siding panel unit of  claim 1  wherein said second side comprises at least one ridge adapted to space said second side apart from said wall to enable ventilation between said backing portion and said wall once said panel unit is secured to said wall. 
     
     
         6 . The siding panel unit of  claim 1  wherein said second side comprises at least one channel adapted to facilitate water escape. 
     
     
         7 . The siding panel unit of  claim 1  wherein said second side comprises at least one ridge and at least one channel relative to a primary surface, said at least one ridge and said at least one channel adapted to space said second side apart from said wall once said siding panel unit is secured to said wall. 
     
     
         8 . The siding panel unit of  claim 1  wherein said recess has a width of about 0.05 inch. 
     
     
         9 . The siding panel unit of  claim 1  wherein said recess has a depth of about 2.0 inches. 
     
     
         10 . The siding panel unit of  claim 1  wherein said recess starts about 1.250 inches from a top of said backing portion. 
     
     
         11 . A siding panel unit for a wall of a structure, comprising:
 a facing panel; and   a backing portion secured to said facing panel such that a relief zone is formed along an edge of said panel unit between said facing panel and said backing portion, said relief zone adapted to receive a facing panel of an adjacent panel unit such that said facing panel of said adjacent panel unit is situated between said facing panel and said backing portion of said siding panel unit.   
     
     
         12 . The siding panel unit of  claim 11  wherein said backing portion comprises at least one valley adapted to receive adhesive for securing said backing portion to said facing panel. 
     
     
         13 . The siding panel unit of  claim 11  wherein said backing portion is comprised of foamed plastic. 
     
     
         14 . The siding panel unit of  claim 11  wherein said facing panel is comprised of vinyl. 
     
     
         15 . The siding panel unit of  claim 11  wherein said backing portion comprises at least one ridge adapted to space said backing portion apart from said wall to enable ventilation between said backing portion and said wall once said panel unit is secured to said wall. 
     
     
         16 . The siding panel unit of  claim 11  wherein said backing portion comprises at least one channel adapted to facilitate water escape. 
     
     
         17 . The siding panel unit of  claim 11  wherein said relief zone has a width of about 0.05 inch. 
     
     
         18 . The siding panel unit of  claim 11  wherein said relief zone has a depth of about 2.0 inches. 
     
     
         19 . The siding panel unit of  claim 11  wherein said relief zone starts about 1.250 inches from a top of said backing portion. 
     
     
         20 . A siding panel unit for a wall of a structure, comprising:
 a vinyl panel; and   a foamed plastic backing portion secured to said vinyl panel, said backing portion comprising at least one ridge or at least one channel relative to a primary surface, said at least one ridge or said at least one channel adapted to space said backing portion apart from said wall once said siding panel unit is secured to said wall;   wherein a relief zone is formed along an edge of said panel unit between said vinyl panel and said backing portion, said relief zone adapted to receive a vinyl panel of an adjacent panel unit such that said vinyl panel of said adjacent panel unit is situated between said vinyl panel and said backing portion of said siding panel unit.
