FireShell® IB4 Interior Ignition Barrier Coating – Premium Fire Protection Solution
FireShell® IB4 is a high-performance, water-based, 1-part intumescent ignition barrier coating designed for interior fire protection and compliant with AC 377 ICC ES for building code requirements. It delivers exceptional passive fire safety by expanding up to 2000% when exposed to heat, starving flames of oxygen and slowing fire spread to structural materials.
This coating is non-flammable, non-toxic, low-odor, and no-fuming, making it safe and straightforward to use while providing reliable fire resistance. Its low viscosity ensures smooth application across a wide range of substrates.
