Dow Rigid Foam Insulation
Extruded Polystyrene XPS
Dow STYROFOAM™ Brand Residential Sheathing is an extruded polystyrene board with plastic film facers on both sides to reduce job site damage to the insulation boards. In new construction and residing applications, it provides a level, even surface for the exterior sheathing and for new siding material. Plus, Dow STYROFOAM™ Brand Residential Sheathing helps enhance energy efficiency, reduce condensation and create an attractive, long-lasting home exterior.
Polyisocyanurate Boards (ISO)
Polyisocyanurate boards are typically a layer of polyisocyanurate foam between two sheets of aluminum foil. Polyisocyanurate sheathing generally provides the greatest R-value per thickness.
- BlueLinx provides Dow polyisocyanurate boards nationwide east of the Rockies.
- BlueLinx provides RMax polyisocyanurate boards on the West Coast.
Dow OX Structural Insulated Sheating (SIS)
Dow OX Structural Insulated Sheathing combines structural lateral bracing and transverse load, insulation and water-resistive barrier properties. It is designed for use as braced wall panels attached next to other rigid insulated sheathing. It can also serve as continuous structural insulated sheathing over the entire structural insulated wall line.

Cellofoam Rigid Foam Insulation
Rigid Foam Expanded Polystyrene EPS
Cellofoam EPS insulation performs. Its R-value is stable and predictable; it won't drift down as the years pass. Plus Cellofoam has the compressive strength and the inherent moisture resistance to withstand forces that can destroy other insulation products.
Cellofoam EPS is easily trimmed with hand tools to fit your specific application, yet it has the strength to absorb normal job site abuse.
