Set interior wall as airwall

Hi all,

I know it may be a silly question, but I have to set a single wall of a HB room as airwall, and I don’t precisely how to do it. I’m using LBT1.6.

Thanks everybody

Hi @mich.dimart you can override the standard generated innerwalls with the "HB properties by guid surface component.

You could also use, depending on your zone setup, Solveadjacency:
