Support Panels are made of extruded foam and designed to use as a strong, but lightweight terrain understructure. They are quick and easy to use. Cut easily with a hot wire foam cutter, knife or scissors. Top with flat foam board surface or cover with paper or plaster cloth to form a higher level of scenic terrain.
