The cut edge of a foam panel is where a DIY wall looks DIY. The best edge trim for foam wall panels covers exposed foam at ceilings, door casings, outside corners and the top of half walls, so the brick looks built in rather than stuck on.
Peel-and-stick trims are the natural match for foam because they install the same way and cut with the same knife. We matched each trim to the edge it handles best.

Match the edge to the trim when choosing the best edge trim for foam wall panels.
