Johns Manville (JM), a Berkshire Hathaway company and leading building products manufacturer announced the launch of JM CladStone™ 110 and JM CladStone™ 80. With this release, JM now offers a full line of product densities on its exterior commercial mineral wool insulation, JM CladStone™ Water & Fire Block. The insulation is offered in densities ranging from 4.5 pcf to 11.0 pcf, making it ideal for use in a variety of exterior cavity wall, rainscreen, and continuous insulation applications.

Johns Manville’s Commercial Mineral Wool Product Manager Eric Dake explained that the varying densities of JM CladStone™ are a crucial component for many installers. “JM CladStone™ mineral wool is a great material for insulating commercial buildings,” Dake said.

“Given the array of installation applications, from the exterior cavity wall to continuous insulation, installers need insulation in a variety of densities so that it can meet the unique demands of the application and installation. With JM CladStone™, installers can choose from four different densities, 4.5 pcf, 6.0 pcf, 8.0 pcf, or 11.0 pcf, that work with a variety of exterior cladding systems,” he said.

The latest release of JM CladStone™ 80 (8.0 pcf) and JM CladStone™ 110 (11.0 pcf) rounds out the JM CladStone™ portfolio, offering a variety of densities for diverse and varied applications and installations. Each of the insulations in the CladStone™ portfolio is ideal for continuous insulation applications and exterior wall assemblies. As part of a continuous insulation assembly, CladStone™ helps improve a building’s energy efficiency and temperature control by decreasing or preventing thermal bridging. This can be a key component to meeting many of the newer energy code requirements for building insulation.

JM CladStone™ is non-combustible, making it an exceptional solution for fire-resistant applications. Additionally, JM CladStone™ is water-resistant and allows for effective water drainage from an exterior cavity wall assembly.

As codes evolve to incorporate more and more stringent requirements for insulating materials, insulations like JM CladStone™ that offer thermal control, acoustical performance, fire-resistance, and water-resistance will prove to be robust solutions for ever more challenging applications. JM CladStone™ Water & Fire Block is available to customers in the United States and Canada. For more information about the JM CladStone™ Insulation portfolio, visit www.jm.com/cladstone
