Claim:
A system for mounting wall panels to an existing wall structure, comprising: a plurality of wall panels, each wall panel having a main panel section and L-shaped hook walls at edges of the main panel section, with the main panel section and each L-shaped hook wall together defining a U-shaped cross-sectional profile, and with one free wall of each L-shaped hook wall being in parallel spaced relation to the main panel section; a plurality of fastening extrusions, each fastening extrusion including: a fastening extrusion securing section for securing the fastening extrusion to the existing wall structure, and a fastening extrusion connecting section connected with the fastening extrusion securing section, said fastening extrusion connecting section includes first and second female connection sections, each with a recess extending in an outwardly facing direction, with the fastening extrusion securing section including at least one flange extending outwardly with respect to said female connection sections to enable at least two lines of securing elements to secure the fastening extrusion securing section to the existing wall structure; a frame extrusion connected to each hook wall, each frame extrusion including: a frame extrusion securing section for connecting the frame extrusion in a flush relation to said one free wall of a respective said hook wall, a frame extrusion connecting section for engagement with one said fastening extrusion connecting section, said frame extrusion connecting section including first and second inwardly facing male connecting walls for engagement within said recesses of respective said fastening extrusion connecting section, and a spacer wall for connecting said frame extrusion connecting section to said frame extrusion securing section in spaced relation to said hook wall so as to define a gap between said fastening extrusion connecting section and said hook wall when said frame extrusion connecting section is engaged with said one fastening extrusion connecting section; and a cover panel inserted in said gap.
