As both are types of polystyrene insulation, extruded polystyrene (XPS) and expanded polystyrene (EPS) are often seen as very similar. They tend to be viewed as more direct competition to one another than other types of rigid insulation like PIR and phenolic foam. While there are similarities in the applications for which XPS and EPS … Read more

INSULATING BASEMENTS WITH EXTRUDED POLYSTYRENE (XPS)
