Prefabricated construction wall assembly

A prefabricated construction wall assembly, comprising:

• a frame structure having a first thermal expansion coefficient;
• and
• a panel configured for covering at least a majority of a face of the frame structure, said panel having a second thermal expansion coefficient different from the first thermal expansion coefficient, and a solid-surface exterior face exposed to an exterior of the prefabricated construction wall assembly and an interior face connected to the face of the frame structure so as to withstand thermal structural differences between the frame structure and the exterior face;
• a plurality of mechanical adapters for providing said connection of the interior face of the panel to the frame structure in a direct manner, wherein each of said plurality of mechanical adapters comprises:
• a first end configured to be securely introduced into the frame structure;
• a second end facing away from the first end and having a surface for mounting the interior face of the panel to said mechanical adapter;
• and
• a body extending between the first end and the second end;
• wherein said second end having a circumcircle diameter which is greater than a circumcircle diameter of the body;
• a stopper disposed onto said body between the first end and the second end, and having a circumcircle diameter which is greater than a circumcircle diameter of the first end, and configured for maintaining a predetermined distance between the interior face and the frame structure.
