PowerWool Insulation is a high-performance mineral wool insulation manufacturer delivering advanced, non-combustible building envelope solutions for commercial, institutional, and residential construction across North America. Built for architects, engineers, contractors, and distributors working in increasingly demanding code environments, PowerWool focuses on systems that combine fire safety, thermal efficiency, moisture resilience, and long-term durability.

At the core of the PowerWool platform is a portfolio of engineered mineral wool products designed for both continuous insulation and cavity applications. These solutions are developed to meet modern energy codes while maintaining compatibility with tested wall and roof assemblies used in high-performance construction.

The exterior insulation line includes RigiBoard™, a continuous insulation board engineered for use over steel studs, concrete, and masonry substrates. RigiBoard™ provides high compressive strength, dimensional stability, and consistent thermal performance, making it ideal for rainscreen façades and exterior wall systems. CavityBoard™ is optimized for framed wall assemblies, offering dependable thermal resistance, sound attenuation, and straightforward installation. For commercial façade systems, CurtainBoard™ delivers targeted performance in curtain wall applications where fire resistance, air movement control, and insulation continuity are critical.

Expanding beyond wall systems, PowerWool has introduced its newest innovation: PowerWool Apex 12.5lb Roofing Board. Apex is a high-density mineral wool roofing board engineered specifically for low-slope roof assemblies where fire performance, compressive strength, and long-term thermal stability are essential. Designed for use beneath single-ply membranes, modified bitumen, and protected membrane systems, Apex provides a non-combustible insulation layer that enhances rooftop fire safety while maintaining dimensional integrity under load. Its vapor-permeable structure supports drying potential within roof assemblies, helping reduce trapped moisture risks over time.

Across all products, PowerWool insulation is inherently non-combustible, meaning it does not burn or contribute fuel in a fire event. This makes it a preferred solution for assemblies requiring compliance with stringent fire standards such as NFPA 285 and ASTM-tested wall and roof systems. In addition to fire safety, PowerWool products are hydrophobic yet vapor-permeable, allowing assemblies to resist bulk water while still drying effectively—an important balance for long-term building durability.

Thermally, PowerWool mineral wool delivers stable R-values that remain consistent across temperature fluctuations, while its fibrous structure also provides strong acoustic performance in multifamily, healthcare, education, and commercial environments. Sustainability is embedded in the product line, with mineral wool manufactured from abundant raw materials, incorporating recycled content, and remaining fully recyclable at end of life.

Together, the PowerWool system approach—now extending from exterior walls to low-slope roofing—provides a unified insulation platform designed for modern high-performance buildings. At tradeshows, PowerWool represents a clear message: safer assemblies, stronger envelopes, and smarter building science through engineered mineral wool innovation.
