JM TC (Johns Manville Thermal Coating), also known as Fireshell® TC intumescent coating, is a single-component, water-based intumescent coating designed for application as a thermal barrier over JM open- and closed-cell spray foam products. JM TC is formulated for application over polyurethane foam to reduce heat transfer and surface burning in the event of a fire.

JM TC is formulated to adhere to polyurethane foam and a variety of other substrates. JM TC, when installed properly, will serve as a thermal barrier equivalent in lieu of an otherwise code-prescribed thermal barrier, such as 2" gypsum.
