Perform Guard EPS Sheathing creates a stable R-Value energy barrier needed on all frametype construction. Perform Guard EPS Exterior Sheathing lessens thermal breaks caused by studs, headers, and rim joists. Code compliant exterior weather barriers, such as wood, metal, vinyl, hardboards and face brick are all acceptable sidings over Perform Guard EPS Sheathing.

Features:

  • Breathable material and facings
  • No CFC, HCFC, or HFC
  • Resistant to termites

    Advantages:
  • Can be used in new and rehab construction
  • Reduces air movements in wall
  • Stops dew point/moisture condensation in wall
  • Blocks air infiltration.
  • Construction handling durability.
  • Levels new and old substrates
  • Can use wood, metal, vinyl, hardboard, brick and other sidings
  • Available with foil facing, unfaced, and special order plastic laminate

    Specifications

    Perform Guard EPS Exterior Sheating will be installed tightly where shown on drawings. Provide ASTM type, size, and thickness as stated in drawings or as part of this specification. Install in compliance with applicable building codes.

    Apply material with large headed staples or fasteners, spacing not to exceed 12" o.c. vertically on studs. Regional requirements may dictate increased fastener frequency. Take care to protect material during installation. Install corner bracing as required by code. Apply code acceptable exterior weather barrier per siding manufacturer's recommendations over insulation sheathing.

    Design Consideration: System R-Values can be increased approximately 2.5 with the use of a bright foil laminate. A minimum 1/2" air space on the reflective foil surface of the sheathing is required to achieve this additional R-Value. (Reference: ASHRAE Handbook Fundamentals.)
