ROXUL® 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 which may migrate into the wall cavity; yet allows the breathability necessary for outward drying and effective moisture control.
“New energy codes are driving the need for high performance wall systems and COMFORTBOARD CIS provides a true continuous insulation solution for more energy-efficient wall systems,” said Brian LeVoguer, Vice President, Building Envelope & Specification Sales, ROXUL. “COMFORTBOARD CIS is also highly vapor permeable and sound absorbent, two qualities that are ideally suited to this application.”
ROXUL COMFORTBOARD CIS is available in 1”, 1.25”, 2”, 2.5” and 3” thicknesses, with R-Values of R4, 5, 8, 10 and 12, respectively.
