insulating basement with cellulose
Basement waterproofed on the exterior. Interior is framed out and cellulose is sprayed in. Originally I was told that there would be a vapor barrier against the poured concrete wall but then when they came out to spray the cellulose, the insulating guy said that it isnt needed if properly waterproofed.
Is that correct? I am second guessing now after things are completed. No drywall in the basement yet. Should I add a vapor barrier on the interior?
