COMFORTBOARD™ 110 is a rigid, high-density, non-combustible, stone wool insulation board, and 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.
