ASTM C578 Type X, 15 psi, 1.3 pcf density

All-purpose foam panel insulation for masonry and other applications. Owens Corning FOAMULAR® 150 extruded polystyrene insulation is ideal for wall furring, perimeter/foundation, cavity wall, crawlspace, pre-cast concrete, under slab, sheathing and other applications (Not approved for roofing). Owens Corning’s patented Hydrovac® process technology makes the unique closed-cell structure of FOAMULAR® extruded polystyrene insulation highly resistant to moisture, retaining its long term R-value year after year – even following prolonged exposure to water leakage, humidity, condensation, groundwater and freeze/thaw cycling.

High-performance FOAMULAR® 150 extruded polystyrene insulation works to:

  • Retard the transmission of water vapor and moisture in masonry walls, helping prevent structural damage.
  • Provide insulation in a metal or wood furring system used for masonry or concrete walls.
  • Perform below grade in perimeter and foundation applications to complement the insulating sheathing envelope around the building framing.

Resistant to common soils and decay, Owens Corning FOAMULAR® extruded polystyrene insulation retains its insulating performance characteristics even after prolonged exposure to moisture.

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