A small insight on how EPS rigid foam insulation manages moisture
Expanded Polystyrene (EPS) is a thermoplastic foam material that is rigid and has closed cells. It is made of solid polystyrene beads that are dissolved in an expansion gas called pentane. Polystyrene is polymerized from styrene monomer. Little pockets of gas within each solid polystyrene bead expand when heat is provided in the form of steam,…
