FS IBTM (Ignition Barrier)

Introduction

FS-IB™ Ignition Barrier is a single component, water-based latex coating for use as an ignition barrier over interior Spray Polyurethane Foam (SPF) insulation. FS-IB™ uses intumescent technology to protect SPF from flame source impingement. FS-IB™ is designed specifically as a protective coating over spray foam insulation in non-occupied areas, such as crawl spaces and uninhabited attics in both residential and commercial structures. The product has been tested successfully under the AC 377, Appendix X test method. FS-IB™ is fast drying and easy to use with standard commercial airless spray equipment Where spray foam system is installed within attics or crawl spaces where entry is made only for service of utilities, an ignition barrier must be installed in accordance with IBC Section 2603.4.1.6 and IRC Section R314.5.4, as applicable. The ignition barrier must be installed in a manner so that the foam plastic insulation is not exposed.
