Hi Manfred, Thanks for the response. The insulated steel studs will typically form the internal part of the wall and would be filled with mineral wool. In this case I believe the thermal impact is large, but the vapour resistance will be dominated by the mineral wool properties. I understand that a ...

I am trying to model a typical UK lightweight metal wall (SFS) supporting a rail based brick slip system. I have modelled the rails as a continuous perforated metal sheet. When I run the model, I am getting nearly 1500 convergence errors and my balances are far apart (4.68 and -158.39). I attach det...

Hi, I am wondering what is the best way to model a wall which comprises metal or timber studs with insulation (mineral wool or rigid foam) between each stud? So far I have effectively averaged the thermal conductivity and vapour resistance using an area weighted average, but is this the correct appr...
