A fire retardant thermally insulative, vandalism and damage resistant panel for the building exteriors includes a relatively low density foam layer having relatively high thermal resistivity, a relatively high density foam layer having relatively high impact strength and resistance to bending facingly contacting the low density foam layer, a porous fabric contacting the high density foam layer at a surface thereof facing oppositely from the low density foam, and a weather resistant, water impermeable exterior layer contacting the fabric at a surface facing in a direction opposite from where the high density foam contacts the fabric, where the high density foam substantially occupies at least parts of some of the pores of the fabric and the exterior layer material substantially occupies at least parts of at least some of the pores of the fabric such that sufficient pores of the fabric are filled with the high density foam, the exterior surface material and chemical reaction products thereof to create a bond between the exterior surface material and the high density foam.
