What is Cellulose Insulation?
Cellulose insulation is a type of wood- or paper-based product. It insulates empty spaces in the structural part of a house to slow down the transmission of heat or cold. Cellulose insulation is thick, dense, and clumpy, with a consistency much like down feathers. The chief value of this shape and size is that the insulation can fit in enclosed areas (such as walls) and can conform around obstructions such as wires and ducts (found both in walls and in attics).
