  • Compatible with NFPA 285 designs for multi-story assemblies
  • Water- and moisture-repellent
  • Vapor permeable to support wall drying
  • Durable, inorganic composition that does not promote mold, mildew, or decay
  • Dimensionally stable, maintaining performance over time

RigiBoard™

PowerWood RigiBoard

PowerWood RigiBoardRigiBoard™ 80 is a continuous, non-structural and noncombustible rigid mineral wool insulation.

Designed for exterior continuous insulation applications, RigiBoard™ delivers reliable performance in demanding assemblies while supporting moisture management, energy efficiency, and occupant comfort. Its rigidity and compressive strength make it well-suited for mechanically fastened cladding systems and layered wall assemblies.

PowerWool™ RigiBoard™ helps create safer, quieter, and more resilient buildings by resisting fire, repelling moisture, and maintaining stable thermal performance over time. It is intended for use in a wide range of above- and below-grade applications where consistent performance matters.

CurtainBoard™

PowerWool CurtainBoard

PowerBoard CurtainBoardPowerWool™ CurtainBoard™ is a rigid mineral wool insulation board designed for perimeter fire containment applications in spandrel panels and mullion covers. Engineered for high-rise and commercial curtain wall systems, CurtainBoard™ provides noncombustible fire resistance, moisture resilience, and long-term dimensional stability.

Key Performance Benefits

  • Noncombustible and fire resistant
  • Moisture repellent, maintaining long-term thermal performance

ROK-ON™ Structural Insulated Sheathing Board

ROK-ON™ Structural Insulated Sheathing is a structural board applied to the exterior of a thermal barrier. ROK-ON™ eliminates layers of protection traditional systems require and exceeds code requirements for energy and fire performance. The structural insulated sheathing boards allow for simple, direct application of finishes or cladding without expensive attachment systems.

ROK-ON™ is made by bonding a proprietary fiberglass reinforced ceramic cement sheathing (FRCC) to expanded polystyrene foam in a thin structural panel. The EPS core is surrounded by a 6mm sheet next to the framing and a 12mm sheet to the exterior. The result is a 2 ¾” all-in-one structural sheathing that has superior performance compared to common substrates available today.

ROK-ON™ is non-combustible, impact-resistant, fire-resistant, mold-resistant, termite resistant, and water-resistant.  It is the ideal configuration for a continuous insulation substrate.

  • ROK-ON™ products have undergone extensive performance testing in over 63 ASTM tests with outstanding results.

  • ROK-ON™  boards attach like common sheathing.

  • ROK-ON™ boards can accept and hold fasteners for cladding attachment without the need for expensive rail systems.
  • ROK-ON™ exceeds energy code requirements for continuous insulation.

  • 1-hour and 2-hour fire-rated assemblies.

  • The structural strength of ROK-ON™ can help reduce stud size and/or gauge in certain applications.
  • Construction adhesives, caulks, mortars, etc. bond exceptionally well.

  • ROK-ON™ is fully code compliant.
