NEW PRODUCT FLASH: COMFORTBOARD CIS by ROXUL
As a rigid, high density, non-combustible stone wool insulation board, ROXUL COMFORTBOARD CIS (Commercial Insulated Sheathing) is 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 water repellent, providing a tertiary drainage plane for bulk water which may migrate into the wall cavity; yet allows the breathability necessary for outward drying and effective moisture control.
COMFORTBOARD CIS is available in 1″, 1.25″, 2″, 2.5″, and 3″ thicknesses, with R-Values of R4, R5, R8, R10, and R12, respectively.
