FS-IBTM: Ignition Barrier Coating

Introduction

FS-IB Ignition Barrier Coating is a single-component, water-based latex treatment 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 in both residential and commercial structures. This ignition barrier coating 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. 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. Flame Seal IB is available in Standard White, Platinum Gray, or Black.

Application

The standard recommended application method for FS-IB Ignition Barrier Coating is an airless spray equipment. Small jobs or touchups may be performed by roller, or brush. FS-IB must be applied to surfaces free of dirt, grease, loose particles, and any foreign matter. Thorough mixing is required prior to application. Coverage rates may vary depending on SPF density, brand, and testing results. Please seek proper application coverage specs from either the SPF manufacture or a Flame Seal Testing Matrix.
