Steel-to-concrete thermal break Egcobox® FB

Structural thermal break for steel-to-concrete connection

When connection is made between a steel structure and a reinforced concrete supporting structure, it is important to minimise thermal bridges. Due to the high thermal conductivity of steel, heat losses can occur where connections are uninsulated. This is not economical where heating costs, a healthy indoor climate and environmental protection are concerned.

The Egcobox® FB steel-to-concrete thermal break offers the optimal solution for the thermal separation of steel elements and reinforced concrete structures while reliably transferring high loads. Together, with the service provided by MAX FRANK, Egcobox® simplifies balcony design and speeds up construction.


  • Minimises thermal bridges and heat loss
  • High performance and corrosion resistance
  • Certified system
  • Insulation material: rockwool (or polystyrene)
  • Rockwool A1 non-combustible insulation as standard
  • Reliable service – from specification, through to design and on-site support
