What cellulose insulation means
Cellulose is loose fill insulation made mostly from recycled paper treated with fire retardant. It is blown into attics or dense packed into closed walls.
Where it matters on a insulation job
It needs a blowing machine and a hose crew. Quote attics by the bags needed for the target R-value from the bag chart, not by eye. Dense pack walls take more skill and more bags than an open attic.
