Insulation is a product used to protect objects from damage during shipping.
Insulation helps reduce the amount of heat coming into an object, but some of the materials used are not well suited for use in that task.
It is used in many industries, including furniture, insulation for solar panels, and in many types of roofing.
However, it is not the most commonly used insulation in most homes, according to the U.S. Department of Agriculture.
Insulated shipping containers are insulated by insulation, duct insulation, and/or insulation for outdoor air circulation.
