Abstract: Light weight fiber-reinforced polymeric structural building panels and methods; sized, configured for fabrication of non-portable wall structures permanently fixed to natural base. The panel main body, and studs, can be fabricated separately, then assembled to each other to complete panel fabrication. Methods for making the main body are hand lay-up, or pultrusion. Studs are typically pultruded, and subsequently prepared having consistent thickness, flat surface, across the width of the stud end wall which is to be mounted to the main body. Foam blocks are between inner and outer layers of the panel. Foam blocks can be prepared in block clusters before assembly to the main body. In the main body, a fibrous layer is between each pair of next adjacent foam blocks. Intercostals extend “y” and “z” dimensions transverse to the length of the main body. Studs can be mounted to the main body using adhesive, mechanical fasteners, or both.
