1. A method for fabricating a fire retardant, thermally insulative vandalism and damage resistant composite panel that is undercut at an angle at opposing panel edges, for use as a portion of a building exterior, comprising the steps of:

  • a. supplying viscous low density foam material to the interior of a frame in an amount sufficient to cover the area enclosed by the frame but insufficient to fill the frame;

    b. supplying viscous high density foam material to the interior of the frame in an amount sufficient to cover the low density foam material enclosed by the frame but insufficient to fill the frame;

    c. contacting an exposed surface of the high density foam within the frame with a fabric having sufficiently high porosity for migration thereinto of the high density foam material before complete curing of the high density foam material occurs;

    d. supplying an exterior material to the interior of the frame in an amount sufficient to cover the fabric for migration into and through the fabric of a sufficient amount the exterior material to bond with the high density foam material.
