Claim Text:
1. In a system for mounting wall panels to an existing wall structure, including: a plurality of wall panels with each wall panel formed by a main wall panel having an outer facing surface and at least two bent end sections extending at an angle from different edges of said main wall panel and each bent end section having a wall thickness, and a plurality of main fastening extrusions made of a rigid PVC material, each fastening extrusion having a length much greater than a length of a wall panel, each fastening extrusion including: a cut-out recess at only one of the following: a projection at the other of only one of the following: said projections and cut-out recesses have inclined surfaces which engage each other and which have an inclination angle which permits subsequent removal of said wall panels by a pulling action that results in sliding of said inclined surfaces along each other and which biases at least one said bent end securing wall away from the other bent end securing wall, a method of assembling the wall panels comprising the steps of: mounting a plurality of said main fastening extrusions to the existing wall structure in a predetermined parallel, spaced apart relationship corresponding to dimensions of said wall panels, pressing one said bent end section of a first wall panel having said one of a cut-out recess and a projection, into said second spacing between one said bent end securing wall of one said fastening extrusion and said at least one further wall to cause said one bent end securing wall to be biased away from the at least one further wall until a point where said one bent end securing wall springs back so that said projection engages in a respective said cut-out recess to releasably lock said bent end section in said second spacing and said distal end of the at least one further wall is spaced from the outer facing wall of the first wall panel and such that the inclination of the inclined surfaces which engage each other permits subsequent removal of said first wall panel by a pulling action that results in sliding of said inclined surfaces along each other and which biases said one bent end securing wall away from the at least one further wall, and pressing one said bent end section of a second wall panel having said one of a cut-out recess and a projection, into said second spacing between the other said bent end securing wall of said one fastening extrusion and said at least one further wall to cause said other bent end securing wall to be biased away from the at least one further wall until a point where said other bent end securing wall springs back so that said projection engages in a respective said cut-out recess to releasably lock said bent end section in said second spacing such that the inclination of the inclined surfaces which engage each other permits subsequent removal of said second wall panel by a pulling action that results in sliding of said inclined surfaces along each other and which biases the other said bent end securing wall away from the at least one further wall and such that surfaces of said two bent end sections which face each other are parallel with each other and are out of contact with and spaced apart by a gap equal to at least a width of the at least one further wall from each other entirely along said facing surfaces thereof, and said distal end of the at least one further wall is spaced from the outer facing wall of the second wall panel, and repeating the steps of pressing for additional wall panels.
