3M Fire Barrier Electrical Box Inserts are a flexible, one-piece fire-rated intumescent insert used to protect electrical boxes by adhering to the inside the box. When exposed to fire, the insert expands to fill up the box preventing the spread of fire and limiting temperature rise.

  • Protection of membrane penetrations for listed metallic boxes
  • Tested in accordance with ASTM E814 (UL 1479) (Certified as a Wall Opening Protective Material, UL Category CLIV).
  • STC rating of 62 when tested in a STC 62 rated wall assembly
  • Flexible
  • Convenient slits for access to wiring
  • Great for new construction and retro fit applications

```html 3M Fire Barrier Electrical Box Insert (EBI)

The 3M Fire Barrier Electrical Box Insert represents a specialized fire protection solution engineered to maintain the integrity of rated fire-resistance assemblies. This innovative product is specifically formulated to address a common vulnerability in building construction: the potential compromise of fire-rated gypsum wall systems when metallic electrical boxes penetrate through them during a one-hour or two-hour fire rating scenario.

The product operates through an advanced intumescent mechanism that activates when exposed to elevated temperatures during a fire event. Upon exposure to heat, the material undergoes a controlled expansion process that effectively seals the internal cavity of the electrical box, preventing flames, hot gases, and smoke from traveling through this pathway. Simultaneously, the material develops a protective char layer that serves as an additional barrier, substantially reducing the material's combustibility and hindering further fire propagation across the wall assembly.

Key Features and Benefits
  • Designed for use in one-hour and two-hour rated gypsum wall assemblies
  • Specifically engineered for penetrations containing metallic electrical boxes
  • Intumescent material expands when exposed to heat sources
  • Creates a protective char barrier to resist fire spread
  • Helps maintain compartmentalization during fire events
  • Supports building code compliance for fire-rated assemblies
