Hygric and Thermal Simulation

Schöck Isokorb® Tool

The HTflux ISOKORB® tool allows you to easily perform calculations and analysis of thermal bridging optimization using the famous ISOKORB® elements of Schöck. The following example will briefly demonstrate the use of this new feature.

Like with all thermal simulations in HTflux you can either start from scratch, drawing your geometry entirely using the HTflux drawing functions, or you can import an existing CAD drawing. After assigning the appropriate materials your model is ready for the simulation:


If you run the thermal simulation you will see that this detail would involve strong thermal bridging causing significant loss of energy as well as low inner surface temperatures. For this reason you will use an ISOKORB® element to prevent thermal bridging.
To add this element in your simulation just push the ISOKORB®-Tool button in the main menu of HTflux. The feature provides a well-structured way to browse through the more than 10.000*) models available .

Start by choosing the basic type that is appropriate for your application:


In the next step you can refine your selection by providing the desired insulation thickness, fire resistance, element-height and shear-force. Finally you can choose the model fulfilling your structural requirements best. (For more information on the products visit the Schöck website.)


Lastly you will be able to choose the reference (anchor) point most appropriate for your detail. This will help you to insert the element smoothly into your geometry.


Insert the ISOKORB® into your detail with just one mouse-click.


You can now use the automatic measurements tools of HTflux to determine the internal minimum surface temperature (or temperature factor f*Rsi). If you apply the ISOKORB correctly you will see that the minimum surface temperature will rise significantly above the levels relevant for mold-formation or condensation (dew-point temperature).


To assess the energetic impact of the thermal bridging (or to prove its elimination now), you can use the automatic PSI-measurement feature of HTflux. This will allow you to easily calculate the so-called PSI-value (or linear thermal transmittance) necessary to calculate the building energy efficiency.


Finally you can use the image export feature or the HTflux PDF-report function to create a comprehensive report of the detail.
