Advanced Insulation’s ContraBlast® Blast & Fire Wall Protection provides a robust lightweight solution for passive fire protection, thermal and blast protection.

ContraBlast® panels are manufactured using Advanced Insulation’s award winning MS400 lightweight syntactic phenolic foam as the core material reinforced with a laminate matrix. A purpose designed multi layer laminate skin is used as a weather proof outer cover. A vacuum resin transfer (VRT) process is used to infuse the components with phenolic resin ensuring a robust bonded integral panel formed without the need for adhesives.

The ContraBlast® system offers over a 50% weight saving against the conventional steel blast wall and the system comes with either a H120 or JF120 fire rating. The system provides resistance to blast pressures of up to 1.5 Bar with the added benefit of space saving in excess of 60%. The panel system is fitted as a dry/cold construction with no welding or extra coatings required and is modular making it easy to incorporate into new design applications or for retrofit to existing projects.


Different ContraBlast® systems are available depending on your specific requirement but the typical applications are the following:

  • Packaged LERs (local equipment rooms)
  • E-houses (electrical houses)
  • Data Rooms
  • Escape Tunnels on topsides structures to provide H60/60 protection
  • Stair towers
  • Stand-alone Fire Walls
  • Stand-alone Blast Walls
  • Retrofit installations offshore


  • Integrated passive fire protection (PFP) and insulation up to H120 & J120
  • Blast rating up to 1.5bar
  • Nominal weight 54 kg/m2 for 1.5 bar application
  • Dry fit installation
  • Space saving
  • Can be designed for Bi-directional blasts
  • Zero welding and therefore no compromise to corrosion coating
  • Zero degradation of PFP after blast event
  • Rigorously tested system for use in an offshore environment
  • 30+ year design life
