Johns Manville Introduces Formaldehyde-free™ Cavity-SHIELD™ Insulation

New product for passive fire protection between floors in multifamily
projects

DENVER–(BUSINESS WIRE)–Johns Manville, a Berkshire Hathaway company and leading building
products manufacturer, announced today the launch of JM
Formaldehyde-free™ Cavity-SHIELD™, a NFPA 13 compliant1,
fiberglass batt insulation for use in the concealed spaces of
multifamily buildings. Cavity-SHIELD provides an alternative solution to
sprinklers in the interstitial space and further increases the breadth
of JM’s full line of insulation products.

Cavity-SHIELD fiberglass batts are a noncombustible insulation product
made up of long, resilient glass fibers bonded with thermosetting resin.
The batts are designed for use in concealed spaces between floors,
serving as a passive fire solution for limiting potential flame spread
between and through floors.

When installed per the NFPA 131, Cavity-SHIELD eliminates the
need for sprinkler systems within concealed floor spaces, saving
construction time and money and eliminating long-term maintenance and
water leaks.

Additional product advantages include:

  • Simple installation: Batts are friction-fit into cavities,
    without the need for special equipment, reducing the time and
    resources required for installers to complete the job
  • Smart engineering: Available in a wide range of thicknesses,
    Cavity-SHIELD can be easily cut with a standard utility knife to fit
    in any cavity size
  • Cost-effective alternative: Cavity-SHIELD is another option for
    construction professionals looking for passive fire protection and a
    cost-effective alternative to blow-in or sprinklers in the
    interstitial space
  • Durability: Fiberglass has proven to withstand the life of the
    project and will not rot, mildew or deteriorate
  • Formaldehyde-free™: JM Formaldehyde-free™ insulation products
    promote higher indoor air quality and environments, while also
    limiting exposure to harmful volatile organic compounds, which could
    cause health problems
  • Sound control: Cavity-SHIELD offers the same acoustical
    reduction benefits between floors when compared to other JM insulation
    products

“Johns Manville is committed to ensuring customers have the product
options available matched to their specific needs, and we recognized an
opportunity to create an alternative fire protection product for
customers with Cavity-SHIELD insulation batts,” said Mandy Schweitzer,
Senior Product Manager at Johns Manville. “Offering a batt product that
combines passive fire protection with the high-quality standards
customers expect from Johns Manville, allows for flexibility in project
options, ultimately saving both time and resources.”
