A pair of splines each in the form of a thin metal strip are inserted into respective grooves or slots adjacent the opposed facings of a pair of structural panels. Each panel further includes an insulating foam core disposed between and attached to the opposed pair of facings. An adhesive applied to the metal splines bonds the splines to each panel and securely connects the two panels along respective abutting edges. In one embodiment, each metal strip is provided with opposed turned-in edges which function as hooks for engaging each panel's foam core and preventing separation of the two panels, particularly during curing of the adhesive. In another embodiment, each spline further includes a foam insulating strip about which the spline's metal strip is substantially wrapped for providing a thermal barrier at the panel juncture. In yet another embodiment, the spline's metal strip is provided with an irregular surface such as grooved or embossed for more uniform application of the adhesive on the metal strip and a stronger bond between the spline and adjacent panels. By bonding the internal splines directly to each panel's outer facing, an inner component in the panel juncture for additional strength is not required and the routing of electrical chases through the panel juncture is simplified.
