Cellulose blown in ceiling insulation is a good choice for diyers. Many green builders aim for a ceiling rated at r 60 r 70 or even r 100. It is applied with a very small amount of water to activate an adhesive of some kind. Blown in cellulose has a higher r rating and is less expensive than either blown insulation like fiberglass attic insulation or fiberglass batts.

This reduces settling and decreases the amount of cellulose needed. When it comes installing cellulose the usual advice is to pile it on.

This can prove advantageous at reducing the overall weight of the product on the ceiling drywall helping prevent possible sag.
