Abstract:
1. A building comprising a frame of a building and a fire retardant, thermally insulative, vandalism and damage resistant exterior wall, wherein the frame of the building is comprised of a material selected from the group consisting of concrete, wood, brick, stucco, mortar, dry wall, plaster and combinations thereof; a. a relatively low density interior foam layer having relatively high thermal resistivity wherein a face of the low density foam layer is directly coupled to the frame of the building, optionally, by an adhesive layer; b. a relatively high density foam layer having relatively high impact strength and resistance to bending, facingly contacting an exteriorly facing surface of the low density foam layer at a face of the low density foam layer that is opposite to the face coupled to the frame of the building; c. porous fabric contacting the high density foam layer at an exteriorly facing surface thereof that is on the opposite side of the high density foam from the high density foam-low density foam interface; d. a weather resistant, water impermeable exterior layer contacting a surface of the fabric layer facing exteriorly and outwardly oppositely from the surface at which the fabric layer contacts the high density foam layer;
