The JM Formaldehyde-free Cavity-SHIELD fiberglass batt, one of Johns Manville’s newest fiberglass insulation products, is specifically designed for insulating and fireproofing the spaces between floors in multifamily projects. When installed according to NFPA 13 guidelines, the batts obviate the need for sprinkler systems within concealed floor spaces, says the firm, saving time and money during construction and reducing the risk of leaks.

The noncombustible batts are made of long glass fibers bonded with thermosetting resin, which won't rot, mildew, or deteriorate over the life of the project, according to the manufacturer. Because the insulation contains no formaldehyde, it limits inhabitants’ VOC exposure and promotes healthier indoor air quality.

Each batt is designed to "friction-fit" into its cavity and requires no additional equipment to install. The product is available in many thicknesses and can be cut to fit with a utility knife.

“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,” says 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.”
