The sheets may also be used to underlay roads and other structures to protect them from soil movements due to freeze-thaw cycles.

As a packing material, Styrofoam sheets come in 1-inch, 3/4-inch and 2-inch thicknesses to provide cushion and insulation to fragile, valuable or heavy items without increasing the weight and cost of shipping.
