DIVIDER PANEL SYSTEMS AND METHODS FOR THEIR MANUFACTURING AND INSTALLATION

In an illustrative embodiment, a panel assembly for partitioning a trailer cargo space is provided including a first insulated panel and a second insulated panel, each insulated panel including a first side vertical edge having a connecting edge, and a second side vertical edge having a connecting edge. One of the insulated panels includes one or more spaced apart vertical cut lines proximate the first side vertical edge, where, when a given cut line is cleaved, the cleaved cut line is configured to form a new second side vertical edge having a connecting edge. A first mating extrusion may secure with a second side vertical edge of the first insulated panel, and a second mating extrusion may secure with a first side vertical edge of the second insulated panel where, upon mating the first and second mating extrusions, an insulated wall is formed.
