Propink Sheathing

PROPINK® reinforced insulating sheathing is an extruded polystyrene (XPS) insulation board with a reinforced skin laminated on both sides for extra damage control on the job-site. The product is ideal for either wood or metal framing construction, and suits a variety of exterior fi nishes. It is designed to withstand job-site damage with a reinforced fi lm laminate which provides an increased level of bend-but-don’t-break strength, fl exibility and puncture resistance. It is highly resistant to moisture and retains its long term R-value year after year—even after prolonged exposure to moisture and freeze/thaw cycling.

Owens Corning’s FOAMULAR® extruded polystyrene insulation is an ENERGY STAR® qualified product.
