JM IC (Johns Manville Ignition Coating), also known as Fireshell® IC is a singlecomponent, water-based intumescent coating designed for application as an ignition barrier over JM open- and closed-cell spray foam products in attics and crawlspaces. JM IC is formulated for application over polyurethane foam to reduce heat transfer and surface burning in the event of a fire.
JM IC is formulated to adhere to polyurethane foam and a variety of other substrates. JM IC, when installed properly, will serve in lieu of an otherwise code-prescribed ignition barrier.
