Installation with MOABAI insertion device
Sample application



• Galvanized steel S250GD with zinc coating thickness of 20 microns
• Sylodyn®: Polyurethane Syloer SR220



  • Load capacity in all directions
  • Saving time and cost to build, because there is no need for additional sound insulation
  • Reduces sound transmission
  • More living space because of additional sound insulation
  • A positive impact on the indoor environment, greater wind resistance, due to isolation SYLODYN along the outer walls
