When continuous, rigid insulation is not an option or is not enough because a secondary water-resistive barrier is desired, housewrap solutions from Dow are the best choice.dow_002

Create a protective, continuous membrane to cover non-insulating sheathings like OSB or cracks and gaps between exterior sheathing and seams of rigid foam insulation with WEATHERMATE™ Housewrap and WEATHERMATE™ Plus Housewrap that is polyolefin-based and provides:

  • Moisture resistance
  • A durable and highly tear-resistant air barrier


Insulated Sheathing

A continuous layer of rigid insulation is the preferred wall solution for providing the ultimate above-grade wall protection because of its high insulating value. Eliminate air dow_003leaks and energy loss through wall studs by surrounding the home with STYROFOAM™ Brand Extruded Polystyrene Insulation, STYROFOAM™ Residential Sheathing or STYROFOAM™ Tongue and Groove from Dow that feature:

  • High, long-term R-value
