Fixing a wet cellulose attic made me question if it's truly eco-friendly.
When cellulose gets damp, it can mold and lose R-value, hurting its green image.

I had a similar leak in my attic that ruined the cellulose. Installing a vapor barrier and boosting airflow fixed it for me, @susan_brown80. Now the insulation stays dry and works like it should.

Ever dealt with a damp cellulose attic? I was totally on board with it being eco-friendly before. Then my own attic got soaked and it was a mess. The mold issues and loss of insulation made me see the downside. It's not so green if it can't handle moisture. That's why your post really hits home for me.

Actually, @susan_brown80, your story points out a gap in how we sell eco stuff. Cellulose is only as good as the house it's in, and lots of old homes weren't built for it. If the roof leaks or there's no air moving up there, any insulation turns into a sponge. The green idea falls apart when we don't fix the building first. It's not just the material, it's making sure the whole attic can stay dry. That step gets ignored too often for the sake of calling something green.
