PowerWool Mineral Wool Insulation
Non-combustible mineral wool insulation, rated zero flame spread and zero smoke developed, for maximum safety in demanding environments.
CavityBoard™
PowerWool™ CavityBoard™ is a semi-rigid mineral wool insulation board engineered for exterior cavity wall and rainscreen applications. Designed for high-performance building envelopes, CavityBoard™ provides long-term durability, fire safety, and moisture resilience.
Its consistent thermal performance and dimensional stability make it ideal for continuous insulation in ventilated and open-joint cladding systems. For added convenience and aesthetic integration.
Key Performance Benefits
- Noncombustible and fire resistant
- 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™
RigiBoard™ 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™ 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
- Dimensional stability, resistant to expansion or contraction due to temperature changes
- Durable, inorganic material that does not support mold, mildew, or decay
- Available unfaced or with reinforced foil facing (RFF) for system compatibility
