JM’s new product is made from volcanic rock for a variety of benefits

JM CladStone Water & Fire Block Insulation

Johns Manville launched JM CladStone Water & Fire Block Insulation, a noncombustible continuous insulation mineral wool product.

Described as a “premium mineral wool product,” insulation allows for the effective drainage of water from an exterior wall cavity system, while offering exceptional thermal efficiency, fire resistance and acoustical performance. With the launch, the company says it is providing the market a rain screen product that works with a variety of exterior cladding systems.

Made from basalt, a volcanic rock, JM CladStone Water & Fire Block is naturally noncombustible, moisture repellent, non-deteriorating, and will not mildew or support corrosion, the company claims.

“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,” said Tommy Knappich, VP and general manager of building insulation at Johns Manville.

Knappich added that “increasingly demanding project requirements” at the job site demand this type of innovation.

JM CladStone can be installed with a variety of exterior cladding systems. It’s available in the U.S. and Canada.

Interesting that they're finally doing what Roxul has been doing for years. I'm going to have to check out the price comparison & see if it's as good. I like that you can take Roxul out of a flood (thinking of poor Houston!), let it dry out, & reinsert it & it's just as good as before. I hope that Manville's is just as good!
