1. A coated article comprising:

  • a coating provided on a glass substrate, said coating comprising;

    a) at least one dielectric layer;

    b) a first contact layer;

    c) a first IR reflecting layer;

    d) a second contact layer, said first IR reflecting layer contacting each of said first and second contact layers;

    e) at least one dielectric layer;

    f) a third contact layer;

    g) a second IR reflecting layer;

    h) a fourth contact layer, said second IR reflecting layer contacting each of said third and fourth contact layers;

    i) at least one dielectric layer;
