FOAMULAR® Insulating Sheathing

ASTM C578 Type X, 1.3 pcf density

Foamular Insulation Sheathing

FOAMULAR® extruded polystyrene Insulating Sheathing (IS), is ideal for either wood or metal framing construction, and suits a variety of exterior finishes. These strong, lightweight, rigid foam panels with a film face provide the durability and damage resistance necessary to meet the rigorous demands of site built construction. In addition, Owens Corning’s patented Hydrovac® process technology makes FOAMULAR® extruded polystyrene insulation highly resistant to moisture. This permits the product to retain its long term R-value, year after year–even after prolonged exposure to water leakage, humidity, condensation and freeze/thaw cycling. FOAMULAR® extruded polystyrene insulation products offer these benefits:

  • High R-value (R-5 per inch of product thickness) is better than wood fiber, plywood or ½ ” gypsum panels.
  • Readily combines with blanket type insulation for greater R-value.
  • Used in fire-rated exterior wall assemblies for application in office buildings, schools, shopping centers and more.
  • Available with tough film facers for added damage-resistance.
  • Easy to handle, cut and install without the difficulties of foil facing.
  • Available in 4’ x 8’ or 4’ x 9’ sizes for faster installation and less labor.
  • Effectively impedes mildew, corrosion and rot.
  • Meets building codes and standards.

Sheathing is a component of Owens Corning’s PINK THERMAL WALL system.

Used as sheathing over all exterior walls in wood or metal framing construction, FOAMULAR® extruded polystyrene Insulating Sheathing creates an effective insulating envelope over the entire structure.

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