OWENS CORNING Foamular Metric Exturded Polystyrene




FOAMULAR-METRIC is a rigid polystyrene foam insulation extruded into boards which develops continuous skin surfaces and closed-cell cores. The cells have interconnecting walls of consistent thickness with no voids. This gives FOAMUALR-METRIC high insulating values, superior moisture resistance and high compressive strength.
