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 commercial applications.

Comfortboard® 110 is a thermally efficient, moisture-resistant, vapor permeable board and takes the place of other external sheathing insulations 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
