Johns Manville (JM), a Berkshire Hathaway company and leading building products manufacturer, today announced the launch of JM Spider® Plus blow-in insulation, a re-engineered blow-in system and the latest addition to the industry’s most complete line of insulation products. JM Spider Plus replaces JM Spider® spray-in fiber glass insulation and is ideal for residential, commercial and manufactured buildings.

JM Spider Plus is designed for installation by professionals using a blowing wool machine and features “Interlocking Fiber Technology,” JM’s latest building science innovation. Interlocking Fiber Technology allows the insulation fibers to spring and lock into cavities with no adhesive or netting. JM Spider Plus achieves an R-value of 15 in a 2x4 cavity and an R-23 in 2x6 walls.

Additional performance advantages include:

Smart engineering: Interlocking Fiber Technology expands into wall and overhead cavities, filling gaps and voids, and creating a shield against elements to achieve Grade 1 installation
Flexible installation: Installs and dries quickly for same-day drywall installation – saving time and money
Clean: Minimal dust and easy clean up on jobsites compared to other spray-in systems

“We re-engineered JM Spider — one of our signature products — to meet the evolving needs of our customers,” said Todd Bridgeford, product manager for Johns Manville. “Professional insulation installers want products that offer cost- and time-effective solutions, and our new Interlocking Fiber Technology delivers the performance enhancements and ease of installation needed for today’s increasingly demanding project requirements.”

“We’ve been installing JM Spider blow-in insulation since 2005, and it’s become a favorite product of ours,” said Ron Novak, owner of Advanced Insulation Systems, Inc., in Traverse City, Mich. “JM Spider Plus held together in wall cavities and in overhead applications, and we’re excited to incorporate it into our product portfolio moving forward.”

JM Spider Plus is available to customers in North America immediately. To learn more, visit JM.com or talk to a product manager.
