Double Wall Construction
Guys I’m curious your thoughts on my building envelope on my home I’m about to build.
Building in cold climate MAINE
ICF foundation with 4″ of insulation under the slab.
Double Wall construction with 12″ wall, blown in dense pack cellulose.
I’m using Zip sheathing for the outside which allows me not to have to put up a vapior barrier on the outside as this will serve the same purpose. And covering with Hardi Plank siding.
Here is where I’m unsure, do I need a vapor barrier on the outside of the interior wall or just sheetrock it ?
Look forward to you reply, we are beginning construction next month.
