Strengthen your building envelope with PowerWool™ RigiBoard™, a rigid mineral wool insulation board engineered for durability, fire safety, and long-term thermal performance.

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.

Key Performance Benefits

• Noncombustible and fire resistant
• Water- and moisture-repellent
• Vapor permeable, supporting outward drying of wall assemblies
• Excellent acoustic absorption for quieter interior environments
• High compressive strength for dimensional stability
• Inorganic composition that does not promote mold or mildew growth
• Stable long-term R-value that does not degrade over time

Why Choose Mineral Wool Rigid Insulation

• Mineral wool insulation offers a unique combination of fire safety, moisture resilience, and thermal stability that makes it ideal for high-performance building envelopes.
• Noncombustible by nature, mineral wool helps contain fire and limit flame spread.
• Vapor permeability allows assemblies to dry effectively, reducing the risk of trapped moisture and condensation.
• Maintains consistent thermal performance over the life of the building.
• Provides compressive strength compatible with screw-through cladding and furring systems.
• Reduces thermal bridging when used as continuous exterior insulation.
• Delivers superior sound control, improving occupant comfort in residential and commercial buildings.
