ROXUL has launched an innovative continuous insulation sheathing board. The COMFORTBOARD™ CIS (Commercial Insulated Sheathing) is a rigid, high-density, non-combustible stone wool insulation board specifically designed for use as an exterior continuous insulation in commercial rainscreen wall systems. Thermally efficient and vapor permeable, COMFORTBOARD CIS provides the rigidity and durability needed for many exterior cladding assemblies, such as lightweight metal and composite panel systems. Its thermal properties improve energy efficiency. Stone wool is also water repellent, providing a tertiary drainage plane for bulk water that may migrate into the wall cavity, yet allows the breathability necessary for outward drying and effective moisture control.
