Thermal break design with 3D view

Simplify balcony design with the free Egcobox® thermal break software in 3D view.

The MAX FRANK software for the design of Egcobox® cantilever connector enables fast and convenient design of thermally insulating cantilever slab connections with intuitive operation.

Compared to other programs available for the design of cantilever connections, user-defined balcony geometry, as well as the support situation and loads, are possible with the Egcobox® software. Additional unique features include allowance for recesses in the balcony slab and area loads applied to the balcony slab and 3D view of the input parameters.


  • Graphic 3D view of the input parameters.
  • User-defined input of the balcony geometry as well as the support condition and loads.
  • Accounting for upstands or recesses in the balcony slab.
  • Free input and positioning of handrail, area, linear and point loads.
  • Calculation and 3D visualisation of the support loads, deflection and Egcobox® cantilever connectors by means of the finite element method.

The results can be produced in various formats - depending on your requirements. The outputs can be a short or long report, a unit order list and a 3D DXF export of the required Egcobox® units as an installation plan.
