Cork sheet (thin).
Cork sheeting is a very useful model making material. In architectural model making, cork can be used in the making of topographical stratified models. It can also be used as a base to lay train tracks on model railway layouts.
Cork has a fine, closed cell structure and low density, provides good insulation for heat and sound and is also difficult to set on fire. All of these positive attributes have led to its being very often used as a natural insulating material. Because cork does not absorb liquids or take on dust or dirt, it is hygienic as well.
