- Styrofoam insulation has an exclusive closed-cell structure and is very resistant towards moisture and water vapors. ...
Is polystyrene foam a good insulator?
Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them. This makes them very good insulators because heat energy can’t flow through them. This stops the movement of air in the space between the two layers of glass and reduces heat loss from the window.
Can I use any polystyrene as insulation?
