Molded Expanded Polystyrene (MEPS) / Extruded Expanded Polystyrene (XEPS) Foam Board

Polystyrene pellets are mixed with various chemicals to liquefy them. A blowing agent is then injected into the mixture, forming gas bubbles, which produce a closed-cell material that are then molded into large sheets. Commonly known as beadboard, it has an R-value of about 4 per inch of thickness.

(XEPS) Foam Board Extruded expanded polystyrene insulation is similar to MEPS, but the foaming, thick liquid is forced through a shaping die.
