Dense pack cellulose in 2×6 exterior wall…how long does it take to dry?
My exterior walls were insulated with damp, dense pack cullulose in July of this year. This week I drilled a 3″ hole through the wall from the interior for a mechanical entry and discoverd the last inch (against the plywood) of the cellulose still somewhat damp with the plywood damp. There was no mold or discoloration as the cellulose had completely filled the cavity…but it was disconcerting to feel the moisture inside my wall cavity (exterior sheathing plywood, typar, cement board, paint).
– how long will it take to dry?
– besides the usual concern for mold and mildew, are there any other concerns with this slow rate of diffusion (interior 1/2 drywall, vapor barrier paint)?
