The Physics of Cellulose Insulation
Cellulose insulation is a renewable material made from plant fiber; mainly wood, but can also be made from cotton, straw, sawdust, hemp, and corncob.
Modern cellulose insulation is made from recycled newspaper by grinding it, removing any dust, and treating it with a fire retardant.
It is actually one of the oldest types of insulation, but has become exceedingly popular in recent years due to several studies that have found it to be much safer in a fire situation and superior in R value to other types of insulation on the market.
It is used in roughly 10 - 15 % of North American homes
Cellulose insulation is made from recycled material
Decreases CO2 released into the atmosphere
It is safer than Fiberglass due to its manufacturing
It has much less embodied energy than fiberglass or polyurethane
Cellulose can be used in retrofits to enhance existing insulation with minimal cost
It can be made locally, and recycled locally
It is actually a really good thermal insulator (extremely high R value).
