Blown Insulation

Can also be wet-sprayed (applied with a water-based adhesive).


Cellulose is made with up to 80% recycled material (shredded newspaper, mostly), it uses less energy than fiberglass to manufacture, it’s non-toxic, inexpensive, more effective than batts at sealing air leaks as well as nooks and crannies, flows around wall studs to increase the R-value of the entire wall, and it’s highly flame-retardant. It’s also easy to retrofit walls with dry-fill cellulose by cutting a small hole (which is later patched) in between each stud at the top of the wall and blowing in the insulation. You’ll also want to remove a piece of drywall at the bottom of the wall to make sure the cellulose has made its way all the way down. Cellulose is also good for retrofitting attics; if it’s distributed evenly you can be sure there are no gaps in the thermal barrier.


May absorb moisture, and can settle over time if not installed properly, both of which reduce its R-value. It’s heavier than fiberglass, so it may cause some ceilings to sag.
