1. A siding panel unit comprising:

  • a vinyl siding panel comprising;

    a first row having a width of at least about 4 inches from one edge to another edge, said first row having a radius curvature between about 63.5 inches and about 300 inches from said one edge to said another edge;

    anda second row having a width of at least about 4 inches from one edge to another edge, said second row connected to said first row by a first seam to define a stepped contour, said second row having a radius curvature between about 31.75 inches and about 215 inches from said one edge to said another edge; and

    a reinforcement panel adjacent to said siding panel, said reinforcement panel having a first portion and a second portion, said first portion adjacent to said first row of said vinyl siding panel and having a radius curvature greater than said radius curvature of said first row of said vinyl siding panel, and said second portion adjacent to said second row of said vinyl siding panel and having a radius curvature greater than said radius curvature of said second row of said vinyl siding panel;

    wherein said radius curvatures of said vinyl siding panel are determined prior to said vinyl siding panel being positioned adjacent to said reinforcement panel such that the radius curvature of said first row is greater than the radius curvature of said second row;

    wherein said vinyl siding panel is secured to said reinforcement panel such that said radius curvatures of said first row and said second row of said vinyl siding panel are increased; and

    wherein said siding panel unit has improved resistance to oil canning relative to a similar siding panel unit that has straight siding panel rows with no radius curvature prior to being secured to a reinforcement panel, such that said siding panel unit simulates the appearance of straight face siding.
