About Comfortboard®

Enhance your building envelope with ROCKWOOL Comfortboard®, a rigid stone wool insulation board that provides exceptional fire protection, energy efficiency, and versatility.

Available in two product options to support specific structural requirements for your next project, Comfortboard 80 and Comfortboard 110 products are used with screws through strapping and insulation cladding support systems.

Comfortboard enables the creation of safer, more comfortable buildings that resist moisture and reduce energy costs. It's engineered for use as exterior continuous insulation in both above- and below-grade exterior walls, under-slab, exterior-insulated stucco assemblies, and in pitched roofs.

Why use stone wool insulation

• Noncombustible and fire resistant, stone wool works to contain a fire and prevent its spread.
• Vapor permeable enabling wall systems to have superior drying potential, minimizing the risk of condensation and water accumulation.
• Stable long-term R-values for superior thermal performance.
• Superior compressive resistance and compatible with screw-through mechanically-supported cladding systems.
• Reduces thermal bridging through wood framing, leading to a higher-performing building envelope.
• Stone wool provides excellent noise reduction and sound absorption to help you create quieter, more productive environments.

Applications

• Installed in above-grade walls as continuous exterior insulation (ci).
• Below-grade exterior-insulated foundation walls and basements.
• Under flat concrete slabs.
• One-coat and three-coat insulated stucco cladding.
• Wood-framed cathedral ceilings.
