Open component in de U-waarde-calculator


Is it possible to fix certain parts, for example sandwich panels, with self-drilling screws.
And calculate their influence on the global U value of the wall?

Thank you very much

you mean to calculate just the influence of the screws?
I don't think it's possible nor helpful?
For which purpose?

In the epb declaration (energy performance and indoor climate of a building), the penetration of the insulation through anchors, self-drilling screws ... must be taken into account. Otherwise, fines are imposed.
It is therefore very useful to be able to determine its influence on the U value (or R value) of an outer wall.
It is impossible to enter sandwich panels in the software that is available to make your declaration.
In essence it comes down to providing a possibility of splitting a material into two parts, as you can do it with 'balken/sparren einfugen' but any material that is a percentage of the surface.
I hope that a solution is found for this.
Kind regards.
