Comfortboard® 110 is a rigid, high-density, non-combustible, stone wool insulation board

Comfortboard® 110 is designed for use as an exterior continuous insulation in residential and commercial applications when enhanced compressive strength is required.

Comfortboard® 110 is a thermally efficient, moisture-resistant, vapor permeable board and takes the place of other exterior continuous insulation materials to create high-performance wall assemblies. These assemblies are effective against fire, moisture and thermal bridging, and allow for superior drying potential.

Properties:

  • Vapor Permeable
  • Fire-resistant, non-combustible product with a melting point of approximately 2150°F (1177°C)
  • Environmentally Sustainable
  • Moisture-resistant
  • Stable long-term R-value
  • Dimensionally stable
  • UV-resistant
  • Sound absorbent
  • ROCKWOOL™ can contribute to earning LEED® points
