Johns Manville has announced the launch of JM Formaldehyde-free™ Cavity-SHIELD™, a NFPA 13 compliant, 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.
Batts are friction-fit into cavities, without the need for special equipment, reducing the time and resources required for installers to complete the job. Available in a wide range of thicknesses, Cavity-SHIELD can be easily cut with a standard utility knife to fit in any cavity size. 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. Fiberglass has been proven to withstand the life of the project and will not rot, mildew, or deteriorate. 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. Cavity-SHIELD offers the same acoustical reduction benefits between floors when compared to other JM insulation products.
