Our 3M™ Interam™ Endothermic Mat E-5A-4 is an easy-to-install heat-absorbing wrap system that provides excellent fire resistance for structural steel components, critical electrical components and wall opening membranes. When exposed to intense heat, the mat releases chemically-bound water to cool its outer surfaces. Installers can easily cut the material to fit even complex installations.

  • Provides protection against intense fires including hydrocarbon pool fires
  • Endothermic design releases cooling chemical-bound water when exposed to extreme heat
  • Versatile – rated for structural steel, electrical circuits, wall opening membranes
  • Flexible – easy to cut and configure for installation on complex shapes and around corners
  • Non-corrosive and requires no maintenance when properly installed
