Berkshire Hathaway’s Johns Manville has announced the launch of JM CladStone™ Water & Fire Block Insulation, a noncombustible continuous insulation mineral wool product designed to provide water drainage from an exterior wall cavity system alongside thermal efficiency, fire resistance and acoustical performance.
The CladStone Water & Fire Block is designed specifically for use in cavity wall and rain screen applications. Its high-fiber density, low shot content mineral wool is composed of basalt, which is naturally non-combustible, moisture repellent, non-deteriorating, and mildew- and corrosion-proof. It can be installed with a wide variety of exterior cladding systems, including strapping, brick ties, and girts and purlins, and supports impaling pins, screws and washers, insulation fasteners, and plastic cap nails as mechanical fasteners.
“We are committed to providing our customers with an array of products to meet the needs of any project, and that’s why we’re introducing JM CladStone Water & Fire Block Insulation, a noncombustible product designed to aid in managing moisture in continuous insulation systems,” says Tommy Knappich, Vice President and General Manager of Building Insulation at Johns Manville. “We aim to provide the highest level of service to customers and constantly look for opportunities to enhance the versatility of our high-performance insulation product line to meet the needs of today’s increasingly demanding project requirements.”
JM CladStone™ Water & Fire Block is now available across the United States and Canada. www.jm.com
