Passed the city insulation inspection. What, you’ve never heard of that you say? Neither did I until the inspector’s last visit when he told me when to call him back.
Adding the vapor barrier was a ton of work. Up and down a ladder many many times and the poly film would rip out from under the staples its own weight if I wasn’t careful. I found it easiest to temporarily hang it with ~15 staples which I would rip out as I flattened the wrinkles while positioning the poly film.
