Fire and blast resistant


Fire and blast resistant walls for any project

InterDam has a large variety of fire and/or blast fire walls, including our G21 panel and our welded wall systems.
All systems range from A0 to H120 fire rating. Jet fire resistance is also available. Blast walls have been tested up to 2.5 bar overpressure. Our G21 panels are also Fire-Post-Blast certified, having the proven ability to withstand a H120 fire after a 0.25 bar blast.

Our G21 Fire Panel is a revolutionary sandwiching fire wall that brings significant advantages over traditional wall systems:

  • Increased cost-efficiency
  • Quick installation (no hot-work required)
  • Minimum weight
  • Easy post-installation of penetrations
  • Equipment of 30 kg may be attached to the panels without compromising the fire rating
