I am wondering if anyone out there has built new lath and plaster walls? I have a wall framed and wool batts installed, the issue is I know the plaster will touch the insulation and that seems like it would be a bad thing. Let me know if anyone has run into this, thanks!

I dont thinl plaster touching the insulation will be a problem, because the work of insulating takes place within the wool itself.
Lathe and plaster seems over the top when sheets are available now?

Hey Maggie.
I don’t think that lime plaster touching the wool (mineral wool or what type is it?) should be a problem either.
And also I think you could have an easier (and cheaper) solution by attaching (split) bamboo rolls or willow rolls (the ones used for shade etc) to the studs. We usually space them 20-30” apart and then plaster over them. First layer of plaster quite liquid in consistency so it penetrates between the bamboo or willow.
Best wishes and keep us updated!
