Styrofoam Packing Peanuts As Insulation

Styrofoam is the white foam used in inexpensive ice chests and packing peanuts.

Styrofoam packing peanuts as insulation.

Packing peanuts are made from styrofoam which is one of the reasons why they are such. The flow of heat energy. In a wall cavity they would offer little resistance to air movement so they would be of limited r value. Hold it in and then the van walls.

Heat energy gets lost as it goes from a hot object into a colder one in three different ways. I m not looking for super insulation just sound dampening and some insulating effects. Another problem is that newer environmentally friendly cornstarch peanuts dissolve when wet. I m curious would styrofoam packing peanuts work as insulation for the transit van.

Insulation with styrofoam. Seems it would be easy. The insulating properties are excellent and elevated temperature tolerance is good. The very reason why plastic peanuts work well as packing makes them a bad choice for wall insulation.

Plastic peanuts hold air that helps cushion whatever is being shipped. It is an excellent insulator but cannot tolerate elevated temperatures.
