Insulated Sheathing

EnergyShield Wall Insulation - Insulated Sheathing

Atlas EnergyShield® rigid wall insulation is a closed cell polyisocyanurate (polyiso) foam core, faced with a reflective foil facer on the front and a non-reflective, red acrylic-coated facer on the back. EnergyShield® wall insulation combines high R-value, durable foil facers, and water resistive attributes in a high performance rigid insulation board. EnergyShield® is suitable for a variety of continuous insulation (CI) applications.

Panel sizes are 4' by 8' or 4' by 9'. Panels can be supplied in nominal 16" or 24" widths for use in cavity wall applications. Custom sizes are also available.

EnergyShield® Wall Insulation Applications

EnergyShield® wall insulation is recommended for use in residential applications as well as Type V light commercial construction.

Common applications include: 

  • Exterior or interior insulated sheathing for walls framed with wood or steel studs (with a thermal barrier)
  • Exterior cavity walls
  • Exterior or interior CI (with a thermal barrier) for cmu/block/concrete wall systems
  • Exterior CI for installation over wood or gypsum sheathings
  • Use over existing cladding to improve energy efficiency and provide a level surface prior to installing a new cladding
  • Approved for use in attics and crawlspaces without requiring the use of a thermal barrier (ICC-ES A12, Appendix B)

    Exterior Sheathing

    The current International Residential Code calls for continuous insulation or insulating sheathing in certain zone climate zones. These requirements will likely be increased and or extended to other climate zones. The next IRC will require the installation of a layer of continuous insulation over the entire exterior of walls of many one and two family dwellings. This requirement will provide for a “thermal break” and added R-value to the structure - making the building much more airtight and energy efficient, as compared to current and past required construction. Atlas can help you meet these needs with our versatile line of wall insulation products.

    Water Resistive Barrier System

    The use of EnergyShield® can be considered a WRB and potentially part of an air barrier assembly. In these types of installations it is required to tape or seal all joints between boards and at penetrations and openings. Atlas recommends sealing into rough opening flashing and to other portions of the building, including the roof and below grade. Atlas EnergyShield® foil facers are compatible with most standard joint fillers, sealants and adhesives. Consult the product manufacturer for specific compatibility. WRB Tapes and System

    Precautions/Limitations

    • This product will burn and may contribute to flames and smoke spreading.
    • Design use of this product must always follow local codes, especially with regards to WRB, Air Barrier and Vapor Retarder. Atlas highly recommends the use of a dew point calculation of the proposed wall assembly to determine the types and locations of weather resistive barriers as well as needed insulation thickness/R-value to mitigate any condensation potential.
    • EnergyShield® is not a structural product, local codes must be followed for bracing requirements.
    • Storage: Boards should be stored indoors. If left outdoors for any length of time, keep dry by covering completely with a waterproof tarpaulin. Store on flat pallets elevated at least 4" above the floor or ground and standing water.
    • Follow the cladding manufacturer’s recommendation for attachment of the cladding.
    • EnergyShield® is not intended to be exposed in excess of 60 days. Atlas recommends that all of the wall cladding material be installed within 60 days of installing the product.
