Why is styrofoam a better insulator than plastic? – WisdomAnswer

Witryna9 paź 2024 · A real insulator like expanded polystyrene has coefficient of heat conductivity of about 0.03 - 0.04 W/mK. You need nearly 50 times more dimension in the walls for sand to work effectively. This means the exterior dimensions of your house could be several times bigger than the interior dimensions. WitrynaMost plastics are not good conductors of heat. Making "foam" from plastic can also improve its properties as a thermal insulator. Styrofoam, for example, is an excellent thermal insulator because it contains a great deal of air trapped by the polystyrene.
