Cellulose vs. stabilized cellulose?
Most of the cellulose going into walls here is stabilized cellulose. We had a new insulation contractor tell us this week that he will only put in loose cellulose in walls. (by loose I mean no glue). He said he nets the stud cavities and blows it in at 3.5#/inch, so there will be no settling over time.
He also briefly mentioned that ‘they’ were starting to find serious issues with the stabilized cellulose product, but we didn’t get into that.
Any issues with this method? How do I know the density really is 3.5#? Is there any way to check it?
Will it not settle over time?
