FIG. 24 depicts a cross-section view of an exemplary embodiment of a panel-to-panel juncture 148 of FIG. 21 along line G-G. The panel-to-panel juncture 148 exists between modular wall panels 116 set side to side or end to end as along a wall 12. To span the panel-to-panel juncture 148, an H-shaped bracket assembly 150 may be used. The H-shaped bracket assembly 150 may comprise dual metal channels 152 and a pair of spacers 138. The dual metal channels 152 may be constructed from an extrudable metal by known extruding processes and has two pairs of legs 140 where each pair is spaced apart sufficiently to receive in reasonably snug engagement one of the side edges 130 of a modular wall panel 116 with both wrap-around flaps 132 wrapped around and against the outer skins 126. Each pair of legs 140 is connected by web 142 and together the web 142 and legs 140 define a pair of opposing channels 144 into which the side edges 130 of the modular wall panels 116 may be inserted. Again, each spacer 138 may be made from any suitable material (conductive or none conductive) such as wood, an elastomer, or the like. With this configuration, the shielding extends across both modular wall panels 116 and the panel-to-panel juncture 148.
