Kit and assembly for compensating for coefficients of thermal expansion of decorative mounted panels

A wall panel attachment system for use with a vertically supported sub wall, said system comprising:

• a plurality of elongated profiles adapted to being secured to the sub wall, each of said profiles having a pair of laterally extending wing portions;
• first and second panels, each having a thickness separating front and back surfaces and surrounded by four interconnecting sides;
• a first plurality of individual bunches of reclosable fasteners secured to said laterally extending wing portions;
• a second plurality of individual bunches of redo sable fasteners secured to locations along said back surface of each of said panels and aligning with said first plurality of bunches upon arraying said panels in proximate and opposing fashion to a spaced apart pair of said profiles;
• an elongated supporting component positioned over a central extending location of each of said elongated profiles, said elongated component having at least one inner support surface abutting a flat surface of said elongated profile, an exterior of said elongated component further exhibiting profile edges which define contact locations with angled back edges of said panels and upon said panels being attached to said profiles;
• and
• displacement of said panels in at least a lateral direction relative said elongated support component maintaining a constant edge spacing between said panels owing to a floating arrangement of said supporting component between said panels and elongated profile, and accommodated by movement of said inner support surface upon said flat surfaces of said profile.
