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.

When To Spray An Ignition Barrier?

If a home has spray foam insulation in an attic or crawl space, the building code requires using materials or assemblies that offer some fire resistance but not as much as is required for a thermal barrier. If you have spray foam insulation in an attic, for example, it’s probably already separated from the living space by a thermal barrier. Most ceilings are made of 1/2″ drywall. But the spray foam is still exposed to the attic and needs an ignition barrier.
