ROCKWOOL COMFORTBOARD® 80

ROCKWOOL Comfortboard® 80 thermal insulated sheathing is a rigid stone wool insulation board that has the added benefit of allowing fast outward drying. The insulation also reduces thermal loss resulting in improved long-term thermal performance.

Comfortboard 80 does not produce smoke or propagate flames, providing a critical line of defense that keeps occupants safe and reduces property damage in the event of a fire. The product has been certified by the California State Fire Marshall’s Building Materials Listing Program (BML).
Comfortboard 80 has ICC-ES (CCMC) validated product acceptance in accordance to IRC and IBC for the following:

  • Non-structural thermal insulation in non-fire-resistive rated dwellings
  • Exterior perimeter insulation around foundation
    Under flat concrete slab
  • A component of residential wood-framed cathedral ceilings
  • In areas where probability of termite infestation is ‘very heavy’
  • Exterior Wall Insulation: Thermal Insulated Sheathing
  • Designed for use as an exterior continuous insulation in residential and commercial construction
  • Fire resistant stone wool can withstand temperatures of approximately 2,150°F (1177°C).
  • Vapor permeable enabling wall systems to have superior drying potential, minimizing the risk of condensation and water accumulation.
  • 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.
